Breakthrough in monolithic bipolar membrane technology

Sinochem News Beijing Tingrun Membrane Technology Development Co.

Huang Quansen, the chairman of the company, introduced that in the traditional zero discharge of wastewater and resource utilization, there are problems such as high operating costs, large investment, and solid waste such as crystalline salt during the treatment process

To this end, after years of research and development, Tingrun adopted a patented technology impregnation method, using polyethylene membrane as the raw material membrane, and grafting anion exchange groups and cation exchange groups on both sides of the base membrane through chemical reactions, and developed a monolithic type.

According to Huang Quansen, the bipolar membrane technology simplifies the process and can convert low or worthless salts into reusable chemical raw materials

"Under the same processing conditions, the equipment cost of Tingrun bipolar membrane is about 60% of the imported membrane, and the operating cost is about 80% of the imported membrane.

According to statistics from the China Membrane Industry Association, by the end of the 13th Five-Year Plan period, the output value of membranes and related industries was over 250 billion yuan, of which the proportion of the core bipolar membrane output value has been increasing in recent years
