WwTP Simpelveld 2017

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.

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

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
