·A pharmaceutical company in Ningxia adopted the double membrane process to reuse the reclaimed water for cooling water and reduce part of the wastewater.

[Project Introduction]

A pharmaceutical company limited in Ningxia is a large biological fermentation pharmaceutical company. The company produces a large amount of biological fermentation wastewater every day. The wastewater is discharged after biochemical treatment by the company. In order to save water and realize wastewater reuse, the company uses ultrafiltration/reverse osmosis (UF/RO) dual membrane system for wastewater reuse. The project was started in December 2012 and put into use in March 2013. So far, it is in good operation condition and the quality of reused wastewater meets the cooling water quality standard.
