Diffusion Dialysis (DD) Acid Recovery Membranes, developed by Shanghai Sanji New Material Technology Co., Ltd., are specialized membranes designed for aluminum profile, titanium dioxide, stainless steel, electronic etching, aluminum foil, and surface treatment enterprises. These membranes address critical industry pain points including high waste acid treatment costs, excessive fresh acid consumption, and large volumes of neutralization waste salt. Key differentiators include a domestically exclusive phosphoric acid recovery membrane and processing efficiency twice that of domestic peers. To date, the product has served hundreds of enterprises across China and Southeast Asia (Malaysia), helping users achieve an 80%-90% acid recovery rate and over 95% metal ion rejection rate. Certified with ISO9001, ISO45001, and high-tech enterprise qualifications, it complies with global environmental standards and is recognized as a benchmark in waste acid resource recovery.
