Case Study

Outline of the Facility: 
A washing company in Shanghai of a total area of 1800 ㎡ with a 600 ³/ D treatment capacity, which was equipped with a total of 3 groups of PE150-200-2S membrane modules ,had been put into operation in 2018.

The influent COD concentration of the biochemical tank is about 400mg/l, the suspended solids SS is about 250mg/l, the sludge concentration of the membrane tank is stable at about 8000mg/l, and the effluent COD  is less than 50mg/l. Cleaning and maintenance are carried out every 3 months with a stable membrane operation.
