Case Study

Outline of the Facility: 
A hospital in Xinxiang of a total area of 1800 ㎡ in Henan with a 600 ³/ D treatment capacity, which was equipped with a total of 8 groups of PE150-150 membrane modules ,had been put into operation on June 2015 , and then replaced its membrane elements on March 2021.

The influent COD concentration of the biochemical tank is about 380 mg/l, the sludge concentration of the membrane tank is stable at about 11000mg/l , the effluent COD is about 35mg/l, the number of fecal coliforms is less than 100 pcs /l, and the ammonia nitrogen is 5mg/l.  Cleaning and maintenance are carried out every 3 months with a stable membrane operation.
