With the primary purpose of clean production and sustainable development process of waste water recycling promoted by the country, and in response to the national environmental protection policy, the membrane integrated technology based on bipolar membrane electrodialysis technology researched and developed by the company has been applied to the process improvement of the chemical industry, and the test of waste water recycling has achieved fruitful results, It has become an engineering R&D and application unit of membrane technology that popularized and applied the bipolar membrane electrodialysis process to industrial production earlier in China. So far, it has accumulated many years of technical experience, and has gained good reputation through the application and practice of many projects. It has been rapidly promoted and applied in industrial special separation, material concentration, water resource purification and reclaimed water reuse, and has made certain achievements in the improvement of wastewater treatment process in pharmaceutical, chemical, biological products, food and other industries.
