1 Nieuwsbrief Sanitary Engineering Uitgave: TU-Delft Faculteit CiTG sectie Sanitary Engineering Redactie: Mieke Hubert Luuk Rietveld Bouke Kooreman Contact: Postbus GA Delft Internet: Nummer: 12 e jaargang nummer 3 Juni 2012 Redactie Ik zit aan mijn tafel op de dag dat het Nederlands voetbalelftal de alles beslissende wedstrijd tegen Portugal moet spelen. Wat leuk is, is dat je iedereen succes kunt wensen, er is geen concurrentie, we zijn allemaal voor hetzelfde. Wat ook leuk is, is dat iedereen een mening heeft: Huntelaar er in of niet, Robben links, Van Bommel eruit, etc. Zelf ben ik een hockeyer en vind ik voetbal hopeloos ouderwets. Om te beginnen dat je niet continu mag doorwisselen, dat buitenspel nog bestaat, dat je geen gebruik kunt maken van de videoscheidsrechter. Dit zou voetbal een stuk eerlijker en aantrekkelijker maken. Verder vind ik voetbal veel te traag. Het feit dat professionals niet eens 90 minuten lang er voor kunnen gaan vind ik vreemd. Dan moeten ze gewoon harder trainen in plaats van alleen maar die eeuwige rondootjes oefenen. Maar het aller stuitendst vind ik het gebrek aan inzicht van de coach. Een moderne coach (zoals in het hockey) kijkt naar het materiaal dat hij heeft en smeedt daaruit een elftal. In dit geval dus gewoon een systeem. Bert van Marwijk houdt echter vast aan een (verouderd) systeem en zoekt daar mensen bij die uit vorm zijn. Het is verder al lang bekend dat hoekschoppen er maar in 3% van de gevallen in gaan en als je deze spelhervatting indirect doet dat je het rendement verdubbelt. Wat doen wij. Altijd maar weer die ballen voor de pot slingeren. Verzin eens iets anders zou ik zeggen. Bij strafschoppen hetzelfde verhaal. Als je ze hoog in de kruising jast, dan zitten ze altijd. Wat doen wij we proberen met een geplaatst laag schot de keeper te verschalken. Een beetje hockeycoach (en coaches van elke andere willekeurige sport) houdt ook bij hoeveel procent van de tijd de bal zich waar op het veld bevindt, turft ook de aantallen goede en foute acties van een speler en past zijn tactiek en wisselbeleid daarop aan. Ik betrap daar onze Bert nooit op. Tot slot houden we vast aan de uitspraak van Cruyff: Wie de bal niet heeft, kan niet scoren. Het Nederlands elftal is al jaren lang wereldkampioenschap balbezit, maar daar krijgen we geen beker voor. Tegen Duitsland hadden we ook 61% van de tijd de bal, maar winnen ho maar. Kortom, voetbal moet veel professioneler: werken voor je geld. Of moet het toch maar zo blijven zodat ik (en velen met mij) mij er over op kan winden. Wat dit allemaal met water te maken heeft weet ik niet, want tijdens de wedstrijd zullen we het ook niet veel drinken. Oh ja, toch, er kunnen weer leuke vraagvoorspellingsgrafiekjes gemaakt worden tijdens de wedstrijd. Voor de rest, allemaal veel SUCCES toegewenst vanavond en lees vanaf morgen maar weer onze uiterst interessante nieuwsbrief. Luuk Rietveld

3 Afstudeer verslagen Anaerobic digestion of the residual fraction from fine sieved sewage: Biodegradability and reactor design criteria Nikolaas van Balkom Introduction Every person uses more than 10 kg toilet paper per year. As a result, almost half of the suspended solids in the sewage consists out of cellulose. To completely degrade cellulose inside the sewage treatment plant (STP), long retention times are required. Fine sieves are able to remove suspended solids and cellulose fibers from toilet paper, directly from raw sewage. This significantly reduces the oxygen requirement in the aeration tank of a sewage treatment plant. Waternet researches this application at STP Blaricum already since 2008 (See STOWA report 2010/19 and 2012/07). A significant part of that research is dedicated to the handling of the residual fraction (RF) produced by the fine sieves. One of the options is to anaerobically digest the RF to produce renewable energy at a decentralized location. This option could also be implemented within the sewer mining concept which is a decentralized approach to obtain high quality water directly from the sewer without the need of a centralized energy source. Residual fraction from fine sieved sewage From literature and lab experiments it was found that the RF has a high solid content: ± 20% dry solids where 80% of the solid content consists out of cellulose fibers. Important is that the RF has bad flow characteristics and a very high organic content: ± 90% of dry solids. It was therefore necessary to consider different digestion techniques as currently applied at Dutch STP s. Reactor configurations from the field of OFMSW (Organic Fraction of Municipal Solid Waste) digestion where therefore considered. For the digestion of OFMSW, often thermophilic plug-flow reactors at high (> 20 %) solid content are applied. The plug-flow configuration enhances mixing and inoculation and the thermophilic conditions benefits the flow properties inside the reactor and can increases metabolic rates. Biodegradability of the residual fraction With help of a number of biomethane potential tests (BMP) the anaerobic biodegradability was investigated. BMP is the maximal methane volume that is produced per mass degraded organic material. First the material is compared with similar substrates (toilet paper, crystalline cellulose and primary sludge). Secondly, the biodegradability at mesophilic and thermophilic temperatures were compared. And thirdly the influence of inoculation on conversion rates was tested. During the MSc project I worked on the assignment to research the anaerobic digestibility of the RF with a reactor design as an end goal. From the results it became clear that the RF has similar BMP compared to toilet paper and cellulose at thermophilic temperatures. At mesophilic temperature the anaerobic degradation of the RF was lower, 3

4 however metabolic rates where comparable. The influence of inoculation on the conversion rates was not significant, however higher inoculation resulted in shorter lag times. Mathematical modeling to obtain design criteria From the lab results, kinetic parameters (the hydrolysis constant and specific methanogenic activity) were obtained by applying (non-)linear regression models. These parameters were input parameters for a twostep anaerobic digestion model. This model contains a hydrolysis step and a methanogenic step. The model is first calibrated with the lab results and results from a completely mixed lab reactor. After this, the model is used to predict the volume, hydraulic retention time and recirculation rate for a anaerobic plug-flow reactor. The 23th of august I will elaborate further on the anaerobic biodegradability and reactor design criteria for anaerobic digestion of the RF. I am available for questions at nikolaas.van.balkom@gmail.com A Probabilistic Decision Making Framework for Sanitation Systems in Low-income Countries The low-sighted leading the clueless, with a map that keeps changing Shirin Malekpour Sanitation, as described by the World Health Organization (WHO), refers to the provisions of facilities and services for the safe disposal of human urine and feces. Countries ( ), followed by declaration of the 1980s as the International Drinking Water Supply and Sanitation Decade by the member countries of the United Nations, led to a global realization about the alternative sanitation options. It was revealed that the required investments in conventional sewage systems exceed the available financial resources in low-income countries and these sanitation options are not likely to reach the huge poor populations in those regions. In the 21st century, lack of access to sanitation facilities by 40% of the world s population sounds like an international scandal. This means that about 2.6 billion of the world s citizens, majorly in developing countries, still rely on a bucket, a bush or a back street for excretion. For years, it was an inheritance of the colonial period to put emphasis on copying the western sanitary achievements by providing sewage coverage in developing countries. The results from a World Bank 2-year research project on Appropriate Technologies for Water Supply and Sanitation in Developing 4

5 In frustration of the failure of the centralized solutions, alternative solutions of small-scale and decentralized systems were proposed for developing countries, but did not remain protected from criticisms. While the centralized versus decentralized sanitation options debate is ongoing, decision makers and planners in developing regions of low-income countries face the dilemma of which path to choose. As various technologies that are required to address the global sanitation crisis are already available, the challenge remains in selection and implementation of appropriate technologies in a way that the desirable outcomes would be resulted. Low-income countries, due to their vast socio-economic inhomogeneity, are more complex target locations for selection of appropriate sanitation options. The dynamic situation in these regions with the rapidly growing populations (specially in the urban settings) and the changing socio-economic structures makes decision making a more fragile process. In the existing sanitation decision making support tools, evaluation of the sanitation options is mostly performed based on predicting the outcomes that best represent a sanitation practice. This kind of representativeness is often used to feed the intuitive judgment with little regard to the uncertainties that lie in these predictions. In these cases the illusion of validity dominates the evaluations, meaning that predictions are done by selecting the outcomes that are most representative of a system, with no or little regard to the factors that limit the predictive accuracy. This thesis recognizes the need for decision making support frameworks to assist the planners and decision makers (specially in low-income countries) in selecting sanitation systems that are more likely to be the appropriate options within their local context. Unlike its predecessor, it takes into account the uncertainties that lie in the decisions to be made, and keeps its distance from making the uncertain certain! For every assessment criterion, the collective judgments that exist among people and even experts with regard to different sanitation options is pinpointed and through real examples from around the world, it is indicated that the expected outcomes are not always achieved in practice. In contrast, this work tries to develop a probabilistic approach in which the evaluation of sanitation systems is done NOT based on intuitive judgments, but with respect to the probabilities that hide in each and every assessment, i.e. the probabilities that the expected outcomes of selecting a sanitation facility occur in practice. To quantify the occurrence probabilities of various outcomes of sanitation facilities, some methods are developed and presented in this thesis. Nonetheless, these methods may not be the only ways of quantifying the assessments. They are rather developed in order to show that, unlike the first impressions that one (and many experts) might get, it is not impossible to quantify such assessments; an impression that have been the major drive for turning into qualitative judgments by over simplifying the reality. s.malekpour@student.tudelft.nl 5

6 Verslagen projecten Report about the workshop Pools 12 Marjolein Peters At the 3rd and 4th of May Maarten Keuten (TU Delft) and Marjolein Peters (TU Delft) organized the first international workshop on swimming pool research, Pool s 12. During this workshop different PhD students and their supervisors joined to give to discuss their work. of you have seen the set-up and therefore you can imagine they found it impressive. We ended the day with some drinks at our department and a diner in De Prinsenkelder. We were happy that at that point the last expected participant joined our workshop. During the diner, we tried to talk about the The workshop was given in the Faculty room of the TU Delft Science Centre. We started the workshop with a tour through the Science Centre, which is more like a shop window of Delft University. In the Science Centre, the equipment of different successful science projects from different faculties of TU Delft is shown. After the lunch professor Ernest Blatchley (US) gave an opening speech via Skype about swimming pool research. Next Maarten showed his findings of initial and continuous bathing load. Were after a discussion was held about the composition of swimmers dirt, alias Body Fluid Analogue (BFA). A little later Marjolein gave weather, but as eager as we were, we also talked a lot about swimming pool research topics. Friday the presentations related to Disinfection By-Products (DBPs) were scheduled. During the first part, the formation under different conditions like ph was discussed by Amer Kanan (Palestine) and Kamilla Hansen (Denmark). Professor Luuk Rietveld led the discussion. her presentations about the microbiology in swimming pools. The intellectual content of the first day was ended with a tour through the civil engineering water lab and the experimental setup of Maarten and Marjolein. Most In the second and third part the removal of DBPs was discussed. Stephan Uhlig (Germany) gave a presentation about the model he developed to predict the formation and the removal of DBPs. Yasmina Bennani (TU Delft) discussed the principle of using photoelctrocatalysis to remove DPBs. This principle was also investigated by use of UV-light by Kamilla Hansen and Mehrnaz Afifi (US, via Skype). Also the quality of water and air was discussed by ShihChi Weng (US, via Skype). Professor Peter Appel gave a presentation about the chemical engineering view on swimming pools. This addition was rather an eye opener about the treatment and as well as the view of the reactor was interesting. 6

7 At the end of the workshop we had a discussion about the needs for further (joined) research and possible topics for a joined publication. There was also a strong wish to continue these kind of meetings on a more regular basis. After the closure of the workshop we all had some drinks in our botanical garden. All with all, the workshop was a big success. To whom it might concern, all presentations were recorded via Collegerama. If you are interested please contact Marjolein Peters and ask for the link. m.n.f.m.peters@tudelft.nl RainGain project Marie-claire ten Veldhuis on methods and experiences in fine-scale rainfall estimation. The experts present at the workshop recommended innovative methods for radar rainfall The RainGain project organized on 16 April 2012 an international workshop on fine-scale rainfall estimation. The workshop brought together about 35 radar meteorologists and urban hydrologists, to bridge the gap between these two disciplines. They discussed the use of new radar technology for measuring the estimation that are to be implemented in the RainGain project in four pilot sites: London, Paris, Rotterdam and Leuven. The implementation of rainfall radars in urban water operational and strategic management will allow urban citizens to be better protected and prepared against risks induced by extreme rain storms. intensity of heavy rain showers over urban areas. Such measurements are required to enable urban floods to be predicted at street or house level. As a result of the workshop, a review document will be prepared j.a.e.tenveldhuis@tudelft.nl 7

8 Kick-off Delft Urban Water, Tuesday, May 29th 2012 Marie-claire ten Veldhuis The kick-off of Delft Urban Water Centre was held on 29 May 2012 in the Library building of TU Delft. Mr van Haersma Buma, Dijkgraaf of Hoogheemraadschap Delfland welcomed the participants and emphasised the importance of research and innovation in the urban water sector to face problems of water scarcity, pollution and flooding worldwide. He stated Delft is the appropriate location for this initiative, given its strong tradition in water research and engineering. Additionally, the city of Delft and its surroundings form a lively example of the challenges of water management in a highly urbanised environment. The dijkgraaf officially opened the kickoff by starting the opening ceremony, launching the Delft Urban Water logo and website: The core part of the afternoon was dedicated to a scientific program consisting of presentations on selected themes of the Delft Urban Water Centre: key note lectures by invited speakers and flash presentations by PhD researchers. The presentations gave a colorful overview of the broad scope of expertise available within the Delft Urban Water Centre, on water quality as well water quantity related topics. Prof Herman Russchenberg presented research challenges under the theme Urban water and weather, followed by three flash presentations by PhD students on disdrometers, roof retention and multifunctional flood defences. Dr Merle de Kreuk highlighted recent achievements and upcoming research themes related to Closing water, nutrient and energy cycles, followed by flash presentations on cold Annamox, smart water reuse, seawater for toilet flushing and zero discharge solutions. Prof Zoran Vojinovic addressed a range of research challenges to find socially-just and ecologically sustainable solutions for Water in megacities. His presentation was followed by flash presentations on the SWITCH project and urban growth modelling. The scientific program was followed by a plenary discussion on challenges for the Delft Urban Water Centre. The discussion was initiated by propositions from representatives of the 4 research institutes involved in Delft Urban Water: TU Delft, UNESCO- IHE, Deltares and KWR. Main topics in the discussion were how to enhance the visibility of Delft Urban Water through the website and other means and how to identify and take advantage of upcoming opportunities for cooperation in project proposals. There was a strong support for Delft Urban Water among the participants and a shared feeling of readiness to get cooperation started. More information about Delft Urban Water can be found on the website: where keynote and flash presentations of the kickoff will be available soon.

9 Visit students ITB Bandung, Indonesia Merle de Kreuk At the 4th, 5th and 6th of June, the section sanitary engineering was visited by 14 MSc. students from Institut Teknologi Bandung (ITB) and their two supervisors Professor Prayatni and Dr. Ir. Marisa. After a touristic tour at our campus, they arrived at CiTG and were welcomed by Jasper Verberk and Bas Heijman and visited the laboratory with the above and Guido Kooijman. After some confusion in the canteen about the Dutch lunches, a full afternoon with presentations was organised. After an inspiring lecture by Anke Grefte about presenting your results, the MSc students presented their thesis work. It was nice to see that they immidiatly tried to apply Ankes tips and tricks and that they recognised when the sheets contained too much information. After their presentations, 4 of our own PhD students gave a flash presentation to give some examples of the waste- and drinkingwater research at sanitary engineering. After this exiting afternoon, they headed to Wateringse Veld by bus, to have a barbeque at Merle de Kreuk house. Due to the bad weather a buffet was served, but it still was a fun night with the students and it is always interesting to see foreigners photographing items in the neighbourhood that are completely unnoted to the inhabitants. The next day, an excursion at WWTP Harnaschpolder was organised by Sigrid Scherrenberg and Merle de Kreuk and the students learned all about Dutch wastewater treatment and water re-use. After a photosession, they left by us to visit Neeltje Jans. On Wednesday Jasper Verberk showed them around the drinking water plant Berenplaat which they combined with a visit to Kinderdijk. It was a nice visit with a lot of information exchange, as the cooperation project with ITB intended. After my week of lecturing in Bandung in April, it was also really nice to meet the same students in Delft again, a good way to establish closer contact. m.k.dekreuk@tudelft.nl Opening week of the first Dutch full scale Nereda sewage treatment plant in Epe Merle de Kreuk After many years of hard work, laboratory scale disasters and pilot scale frustrations, the crowning moment of glory for the Nereda-team arrived at the 8th of May, when the first Dutch full scale aerobic granular sludge treatment plant was officially opened. Excited as a small child in a candy store I drove to Epe in the morning, ready to meet Z.K.H. Prins van Oranje, although that was scheduled very accurately for the afternoon. The atmosphere at WWTP Epe was warm and enthousiastic. During the day al speakers referred to the golden triangle of industry, government and university that has been crucial in the development of the aerobic 9

10 granular sludge technology. I totally agree, without the commitment of TU Delft, DHV, STOWA (or the Waterboards) and STW the Nereda could not have been developed, but I also think it was the enthousiasm in the Nereda team, in which each worked with so much pleasure and drive. It rained heavilly when the Prince arrived, but during the opening ceremony itself, the sun was peaking through the clouds and by starting a mini-installation the installation was officially opened. The other days of the week also other activities were planned, among others with a Benelux Young Water Professionals workshop with the theme Technology Development was organised. 40 (mainly) PhD s from Belgium and The Netherlands discussed the pittlfalls, the ingredients for success and the setbacks of a new develepment. Mark van Loosdrecht started the day with a presentation about the origin of the idea to start the granular sludge development. I was lucky to tell everybody what happened with me during my PhD and post-doc, during the development of the technology and Ruud van Dalen (waterboard Veluwe) discussed the results of the full scale installation up till now and the guts it took to be launching costumer as a Dutch waterboard. After the tour along the treatmentplant and the lunch, we discussed the other succesfull technology Anammox, with Mari Winkler (TU Delft, EBT), who performed a cross over research, incorporating anammox in the aerobic granules, Siegfried Vleaminck (LabMET, Ghent University) discussing the chances in anammox research and Tomasso Lotti (TU Delft, EBT), who told a bit more about the new cold anammox technology (or anammox for the B-stage of an A/B System). In the late afternoon we were tickled by the presentations from Cora Uijterlinde on how to develop a research agenda (WWTP 2030), Jos Paques about technology development in general and the experiences at Paques BV and the thay was closed by Helle van der Roest (DHV) who introduced the fourth P in the people-profit-planet technology development, namely the Passion. Passion could be seen as well on Friday, when many persons working with the aerobic granules during the past 15 years gathered for a barbeque and on saturday, when almost the whole team was present again to explain to the pubblic about this new installation that has been build in their village. I was able to show my invention to my family that day, which I wish for each researcher to experience once: this is the joy to work in applied science! m.k.dekreuk@tudelft.nl 10

11 MSc Watermanagement straks online en op afstand? Peter de Moel Donderdag 14 juni zijn we officieel van start gegaan met het project Online afstandsonderwijs. In dit project gaan we proberen om over 2 jaar onze hele MSc opleiding in te richten dat het mogelijk wordt om op afstand de gehele MSc te doen. Op afstand varieert hierbij van een balkon in Nieuw-Zeeland tot een studentenkamer in Delft. Het project komt voort uit onze MSc in deeltijd waarin medewerkers van waterbedrijven hun MSc opleiding bij ons doen naast hun werkzaamheden in hun bedrijf, en ons Double Degree programma met Singapore, waarin studenten in 2 jaar tijd steeds een half jaar in Delft en een half jaar in Singapore zijn. Daarnaast hebben we inmiddels diverse samenwerkingen met buitenlandse universiteiten, zoals ondermeer IT Bandung, Mozambique, Suriname, Antillen, Australië en Braunschweig. Kortom ons onderwijs is steeds minder gebonden aan de gebouwen in Delft. krijgen. Met deze certificaten zal het mogelijk worden om stapsgewijs het MSc diploma van de specialisaties Gezondheidstechniek te verkrijgen. Hierbij kunnen studenten zich per vak inschrijven en is het niet meer noodzakelijk om voor de gehele opleiding in te schrijven. Voor deeltijders en voor buitenlandse studenten blijkt dit namelijk een hoge drempel om aan een MSc opleiding te beginnen, nog afgezien van de afstand tussen Delft en hun woonplaats. We zullen in het komende studiejaar beginnen met diverse vakken die al op proef online gevolgd kunnen worden. Hierover zullen we in de komende Nieuwsbrief verder verslag van gaan doen. Dit project wordt voor ons gefinancieerd door de TU Delft zelf (CvB via O&S). Het project is een logisch vervolg op onze OpenCourseWare activiteiten, waarmee de afdeling Watermanagement toonaangevend is binnen TU Delft, en ook binnen Nederland. Naast Watermanagement zullen ook de Faculteiten Lucht- & Ruimtevaart en Techniek, Bestuur & Management meedoen, op minder ambitieuze schaal. In dit project gaan we 26 vakken uit de MSc Watermanagement zodanig inrichten dat ze afzonderlijk op afstand gedaan kunnen worden, waarbij studenten een certificaat per vak kunnen Geheel volgens Jasper Verberk s gouden regels start een project met taart. p.j.demoel@tudelft.nl 11

13 Runner-up at the European Inventor Award 2012 Merle de Kreuk In February this year Mark van Loosdrecht, Sef Heijnen and me (Merle de Kreuk) were nominated by the European Patent Office (EPO) for the European inventor award 2012, category research, for the development of the aerobic granular sludge technology Nereda (patents from 1998 and 2004), which has been developed with DHV and the Dutch Waterboards. Very special that our patents were chosen from the 200 entries and the thousands of patents granted each year (already 62,115 granted patents at EPO in 2011). In Kopenhagen we met Boudewijn Zuurdeeg, who was the kind patent officer who came across our invention and thought it would be nice to send it to the contest. The innovation was described as a cuttingedge sewage purification system which uses aerobic granular biomass; bridging biotechnology and civil engineering lead to a solution that drastically improves the quality if waste-water going back into the water cycle, without relying on addition on extra chemicals. It can also make water treatment much more efficient and cost effective ( With this nice description of the aerobic granular sludge technology we could go to Copenhagen for the ceremony on the 13th and 14th of June. Before the EPO would welcome us, we had to do something on our PR, so we were filmed and photographed for 2 full days: in the laboratory, in the office, lecture room, botanical garden, on a boat on the canals of Leiden and even in Madurodam. This lead to two wonderful movies ( finalists/2012/loosdrecht.html and com/watch?v=xzikwephh8g&feature=g-upl) At the 13th of June we were invited to a dinner prior to the award ceremony, were I felt like a true VIP with all the attention of press, especially when it was discovered that I was the only female nominee. On the 14th the award ceremony took place in the presence of the Danish Crown Prince and Princess and the category research was first. Our opponents were Gilles Gosselin, the inventor of a new drug for hepatitis B treatment and Jason Chin and Oliver Rackham, who found a way to incorporate unnatural amino acids into proteins, enabling to understand and control the functions of proteins in cells. Dr. Gosselin won the competition and can call himself European inventor of the year. As Runner up, we were still pretty proud and honored and at least we had a great two days in Copenhagen, among all these great inventors. m.k.dekreuk@tudelft.nl 13

16 Symposium 20 juni 2012 Nieuwegein Energie- en watersector slaan handen ineen Hoe zorgen we voor een duurzame energie- en watervoorziening in de toekomst? Hoe centraal of decentraal zijn we in 2040? Belangrijke vragen, waarbij de energie- en watersector elkaar kunnen helpen. Beide sectoren zijn al volop bezig met besparing, en duurzaam en efficiënt gebruik van bronnen. Met het oog op de toekomst willen de sectoren nog meer leren van elkaars ervaringen en plannen. Om deze kennisuitwisseling vorm te geven, organiseren Deltares, TU Delft en KWR Watercycle Research Institute i.s.m. Stichting Warmtenetwerk op 20 juni 2012 het symposium Energie en Water schrijven toekomst in Nieuwegein. Een visie op de toekomst, met aandacht voor de praktijk van vandaag en morgen. Dat is het uitgangspunt van het symposium Energie en Water schrijven toekomst. De bijeenkomst start met de gezamenlijke toekomst van de energie- en watersector. Ad van Wijk en Jan Peter van der Hoek van TU Delft blikken vooruit naar de energievoorziening en watervoorziening in Hoe (de)centraal, duurzaam en intelligent zijn we dan? Vervolgens gaan sprekers van Stichting Warmtenetwerk, STOWA en KWR achtereenvolgens in op warmte- en koudenetten, de rol van de afvalwatersector en de rol van de drinkwaterwatersector. Thermische energiesystemen De middag behandelt onderzoek en praktijk van thermische energiesystemen.waternet onderzoekt de mogelijkheden van het benutten van energie uit drinkwaterleidingen.

17 Nieuwe medewerkers Başak Savun Hekimoglu I was born in Istanbul, Turkey I received my bachelor s degree in Environmental Engineering in 2008 from Trakya University. I continued to pursue my academic career by enrolling in 2008 into the Environmental Technology MSc. program at the Institute of Environmental Sciences at Bogazici University, Istanbul, Turkey. My MSc. thesis was on the pretreatment of municipal waste activated sludge by advanced oxidation processes. As part of my MSc. thesis, I conducted some complementary laboratory work at Hamburg University of Technology (TUHH) at the Institute of Wastewater Management and Water Protection, Germany. I completed my MSc. degree in 2011 with 3.72/4 GPA. During this time, I also worked as a teaching and research assistant at the Institute of Environmental Sciences, which is a highly competitive position. In April 2012, I have joined the TU delft, Sanitary Engineering Section as a guest researcher and I am currently doing research on brine treatment. b.savun-14@tudelft.nl Mostafa Zahmatkesh My name is Mostafa, born in 1982 in Tehran, capital and most populated city of Iran, very different from delft! So I have a lot to adapt with. I studied chemical Engineering and got my master degree in Chemical- Biotechnology engineering in Sahand University of technology. Our university was in Tabriz, a city in North West of Iran and it was literally on a mountain, so I actually have lived on a mountain for a period of my life. I was working in Tehran institute of biotechnology which belongs to Academic center of Education, Culture & research in Tehran university, as the head of Bioprocess eng. group for 3 years that I learnt about a position in TU Delft, and it was funny because lately I was feeling like developing my knowledge and experience in an advanced university just like TU Delft to get more out of my potential, so I applied for the position and now I am here. Since May 2012, I assigned as a PhD candidate in Civil eng. Department and my project is on design of bioreactors and of course bioprocesses for biodegradation of lignin in effluents using fungi to produce biogass. My two and half years of experience as a journalist, helps me to connect ideas, data and facts together to satisfy my curiosity. One of the best fields to use it is in science and that is my approach. I have a black belt in taekwondo and I am an amateur climber, that s how I practiced to be hard and I m going to use it to nail this project. It s not long since I ve got here, but I already found this city lovely, friendly and peaceful. With these lovely people in our section; Sanitary engineering, I think every thing is ready for a passionate and joyful ride. looking forward to meet all of you. m.zahmatkesh@tudelft.nl 17

18 DP Mainali This is me DP Mainali, originally from Chirang, Bhutan, a small Himalayans country in South East Asia. I am married and since 2005 I have been living in Zuigerstraat, Den Haag with my wife Tulsa Mainali and 3 months baby boy Pranish Mainali. At present I am doing M.Sc. LST- Track Biochemical Engineering at the Faculty of Applied Science at Delft University of Technology. Besides study, I am working as the Chairman of Bhutanese Community in The Netherlands (BCN). BCN is the welfare form for Bhutanese in the Netherlands. It is a non-for profit organisation established to assist on the successful integration of Bhutanese in the Netherlands. Now I am in my final year of University study. In order to complete University study, one of the requirement is to carry our independent research with in TU Delft. This is one of the requirements for completing study at any other University in The Netherlands I supposed. In order to fulfil the above requirements, I choose to do research at the faculty of Civil Engineering and Geoscience, Department of Water management. The project I am working on is Dutch Innovative Pool Project (DIPool) and the topic of my master thesis is Biofilm Development under Swimming Pool Conditions. I am working under the direct supervision of PhD. student Marjoein Peters.My faculty my supervisor is Prof.dr.ir. Mark van Loosdrecht. Swimming pools are a make crossroad of sports, education and entertainment of today s society. Therefore, hygiene and safe pool water is very important in public swimming pools. Nowadays, in all types of traditional swimming pools, hygiene is maintained by the addition of a chemical for disinfection. However, the addition of chemicals has some disadvantages like the formation of disinfectants byproducts (DBPs). Within the DIPool project, a new treatment concept for public swimming pools will be developed, based on advanced UV-treatment. This innovative concept will not use a residual disinfectant like chlorine. Since there is no disinfectant directly in the swimming water, it is likely that on the wall a biofilm will be developed in time. So, during my research, I will investigate how this biofilm will grow and can be limited or removed. Some of the mail research question that will be answered during my research are: 1. How to control the biofilm growth? 2. How fast does the biofilm develop? 3. Different parameters that are influencing the development of a biofilm etc. 18

19 Dispuut Watermanagement Nieuws Dispuut Watermanagement De afgelopen twee maanden heeft het Dispuut Watermanagement veel activiteiten georganiseerd. Het symposium, de bestuurswissel, het zeilweekend. Symposium Het symposium met het thema Water = Energie is bezocht door een groot aantal mensen. Studenten, Phders, professoren en mensen uit het bedrijfsleven waren allemaal van de partij. Met een grote variëteit aan onderwerpen van de productie van biobrandstof door algen tot energy opwekking uit het concentratie verschil tussen zoet en zout water zijn behandeld. Al met al een geslaagde dag. Studiereis op 10 juli 20 studenten en 3 stafleden van de afdeling voor 3 weken naar Mozambique, Zimbabwe en Malawi vertrekken voor de studiereis. Er zullen een groot aantal drinkwater en water beheer gerelateerde projecten bezocht worden. Daarnaast is er natuurlijk ook genoeg tijd voor de toeristische bezienswaardigheden. Naast deze grote activiteiten is er nog een lunch lecture van BAM infra geweest over de BoxBarrier en is Oasen bezocht door Marleen Heidekamp om een presentatie te geven over haar project in Zuid Africa. Als afsluiting van het jaar is er a.s. donderdag 21 juni de eindejaar BBQ. Daarna is het al weer tijd voor vakantie. Zeilweekend Het zeilweekend was een groot succes. We zijn met 22 studenten en staf leden afgereisd naar Bruinisse om te zeilen op het Grevelingen meer. Met een mix van Nederlandse en internationale studenten is er zaterdag gezeild. Er waren zelfs mensen die hun angst overwonnen hebben en zonder te kunnen zwemmen in een zeilboot zijn gaan zitten. dispuut-wm-citg@tudelft.nl Website Dispuut: Website Symposium 2012: Website Studietour 2012: 19
