The specific process is as follows:High ammonia nitrogen wastewater containing heavy metals→PH value adjustment→Sedimentation tank→Mechanical filter→50μm bag filter→middle water tank→Ultrafiltration system→middle water tank→First stage ammonia nitrogen separation membrane system→Second stage ammonia nitrogen separation membrane system→PH regulation→Up to standard discharge

The traditional extraction methods of Stevia need flocculation, precipitation, decolorization of activated carbon, adsorption of macroporous resin and ion exchange. It not only increases the pressure of wastewater treatment, but also greatly reduces the yield of stevioside.

The project is located in a printing and dyeing factory in Jiaojiang, Taizhou, Commissioning time: November 2016. Treatment process:Printing and dyeing wastewater after biochemical treatment→Submerged ultrafiltration tank→Water tank→RO→Water production.

The project is for the treatment of severe polluted river water in urban area. Commissioning time: July 2016. Treatment process: Polluted river water precision →150μm coarse filter→Kaijie X50 elastic anti fouling ultrafiltration→water production.

This project is located in Tianjin Binhai Lake Tourism Resort,the design flux is 1900T/D,there are 2 MBR pools, 4 sets of MBR membranes are placed in each MBR pool,and there are 34 pieces membrane modules in a group MBR frame,there are 136 picecs in two MBR pools,the model of membrane module is KJDF3290A. Project commissioning in May 28, 2016.

In February-April 2016, The transformation of instant tea equipment to increase production for two largest manufacturer f instant tea in Zhejiang province:
