MBR system is used to ensure that its water yield meets the inlet water quality requirements of RO system. In addition, MBR system can improve the treatment effect of biochemical system and improve the quality of effluent. After the RO system treatment, the whole system can make the water quality better. The total emission reduction is realized in a short process, and the operation of environmental capacity replacement is easy to be realized.

"UF+NF+RO+ED" multi-membrane combination combined with concentrated water evaporation and crystallization process was adopted to realize total waste water recovery and recycling of the main salts in the waste water. Zero-emission technologies can both help companies meet stringent emission regulations and save a lot of water. 

 The MBR system is used to ensure that the water produced meets the inlet water quality requirements of NF system. In addition, THE MBR system can improve the biochemical effect and improve the effluent water quality. After the TREATMENT of NF system, polyvalent ions and most of the organic compounds are removed to improve the water quality of the whole system. More than four types of surface emission standards are easy to achieve.

UF system was used to remove suspended solids and colloids from wastewater, and THEN NF system was used to remove more than 98% of polyvalent ions and harmful organic substances, thus improving the water quality standard of tap water.
