Veolia Water Solutions & Technologies, through its subsidiary VWS Rossmark, has installed the compact ActiflocTM plant in order to supply the entire power facility with process water.
The ActiflocTM plant consists of four identical lines capable of producing in total up to 1,280 m3 /h of high quality process water. With the raw water (brackish water) coming directly from the harbour of Rotterdam, the ActiflocTM plant significantly reduces the turbidity of the water and removes any oily pollutants.
After treatment in the ActiflocTM plant, the water has a superior quality and can be used as cooling water directly whereas the water used as boiler water undergoes further treatment consisting of microfiltration by Cartridge filters 5 µm and Clarify filters for oil absorption, reverse osmosis and CDI (continuous de-ionisation).
The ActiflocTM plant combined the proven clarification technology, ActifloTM and a gravity media filter in one prefabricated, fully automatic unit.
The water is initially screened before it is chemically treated and filtered in the ActiflocTM plant. The chemical treatment is based on coagulation using iron chloride and enhanced flocculation using polymer and microsand.
