Zero Discharge System in Shanghai



   Here we provide a 600L/h “zero discharge” wastewater treat and reuse system.

   This system perform to a hydraulic mechanical parts production enterprises of coating line sewage reuse, sewage containing degreasing wastewater, electrophoretic wastewater and wash paint waste water. Except a little sludge entrust disposal, all the treated water feedback to the production line for reuse.

Treatment process introduction:
   Flotation— Sedimentation tank –Ultrafiltration(UF) –Nanofiltration(NF) --Reverse osmosis(RO) –Permeate water reuse
   Concentrated water –Flashing –Nanofiltration(NF)(when dense sludge entrust disposal)

System capacity: 5m3/d,reuse rate≥90%,discharge value≤0.5m3/d

Permeate water quality: PH 6~8, conductivity≤400µS/cm,COD≤40mg/L,SS≤5mg/L,SDI≤2
