Cooling Blowdown and RO Concentrate Reuse Project
A ceramic membrane and reverse-osmosis treatment route for circulating cooling blowdown and RO concentrate at a chemical plant in Dezhou.
Reuse treatment for high-salinity, high-hardness industrial water
The supplied project case identifies circulating cooling blowdown and reverse-osmosis concentrate as the feed. The treatment route combines reaction, clarification, ceramic membrane separation and RO to produce reusable water.
Process route
- Equalization tank
- Integrated high-rate reaction tank
- Clear-water tank
- Ceramic membrane unit
- RO system and product-water reuse
Results reported in the supplied technical file
System recovery
The supplied case table reports an overall recovery of 80%.
Dissolved solids
TDS is listed at approximately 6,000 mg/L in the feed and at or below 500 mg/L in the treated water.
Hardness
Hardness is listed at approximately 2,000 mg/L in the feed and at or below 5 mg/L in the treated water.
Figures on this page are reproduced from the customer-supplied project document. Final performance for a new project depends on its verified design basis and operating conditions.
