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.

Performance：
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.

Some Case Studies Offered：

● Kairui Project (Hotel) of 2000m³/d in Shanghai（2018）

● Wuhan Project of 600m3/d in Hubei Province（2021）

● Shicao Project（Hospital）of P.I 600m3/d，P.II 400m3/d in Shanghai（2017）

● Longyan Project (Hotel) of 200m3/d in Fujian Province（2019）

● Jieyi Project of 1000m3/d in Shanghai（2019）

● Xinchuangfu Project of 300m3/d in Xinjiang Autonomous Region （2019）

● Changzhou Project of 350m3/d in Jiangsu Province（2020）

● Baojiete Project of 800m3/d in Beijing（2021）
