Company Orders Turnkey Zero Discharge System
USFilter has been awarded a contract to provide a multi-million dollar turnkey zero liquid discharge (ZLD) water treatment facility
USFilter has been awarded a contract to provide a multi-million dollar turnkey zero liquid discharge (ZLD) water treatment facility for Calpine Corporation's new 600-MW Rocky Mountain Energy Center (RMEC) near Hudson, CO.
The water treatment system will soften 4,000 gallons per minute (gpm) of raw water for use as make-up to the cooling towers, and will concentrate 390 gpm of cooling tower blowdown with mechanical vapor compression brine evaporators to reduce the volume to the on-site evaporation ponds. The raw water pretreatment system will include two Contraflo® Clarifiers, a thickener, belt filter and chemical feed systems.
USFilter is also supplying the plant's demineralization equipment, which will provide 400 gpm of purified water. This equipment includes multimedia filtration, reverse osmosis and mixed-bed service deionization.
Scheduled for start-up in December 2003, the turnkey system will include all controls, instrumentation, process piping and a programmable logic controller (PLC).
