【Product Overview】

Acid/Alkali Concentration Membranes are a class of high-performance ion exchange membranes specifically engineered for the concentration of acidic and alkaline solutions. This product line is divided into two specialized types: Alkali-Concentrating Membranes and Acid-Concentrating Membranes, which achieve high-efficiency concentration through electrodialysis technology.
