WwTP Simpelveld - performance Per 2016 : strengere normen voor P en N Jaargemiddelde N = 11 mg/l, P = 0,5 mg/l Zomerstreefwaarde: N = 7 mg/l, P = 0,3 mg/l Zandfilters gebruiken voor extra P verwijdering chemisch indien nodig Belangrijk dat de zandfilters goed en continu hun werk doen en inzetbaar zijn op het juiste moment. 5
RFID Technology Data management important to fulfill higher performance Inspired Brightwork to look at the RFID technology RFID known by electronic cat lids, wildlife tracking and monitoring livestock Water sector Sand-Cycle first application Many more possibilities revealing the unknown black box of processes 6
Linking drivers and tools Economic and environmental drivers Asset management is key Performance targets are stretched Operator attendance is reduced Operator tasks are intensified Experiences Site surveys reveal anomalies Refurbishment activities Long term off-the-radar faulty operations Internals design optimization. 7
Standard cloud solution Sand filter(s) with reader datalogger Access to dashboard using browsers Decoder(s) in series On site Cellular transfer Web and database server Internet connection Off site 8
