Diffusion Dialysis (DD) Membrane Stacks, developed by Shanghai Sanji New Material Technology Co., Ltd. (Brand: Smax), are core components designed exclusively for global manufacturing enterprises including aluminum profile, titanium dioxide, and stainless steel producers to achieve efficient industrial waste acid recovery. This product addresses critical market pain points such as high waste acid disposal costs, excessive fresh acid consumption, and large volumes of salt waste from neutralization. Its key differentiators include a domestically exclusive phosphoric acid recovery membrane and processing efficiency twice that of domestic peers. To date, Smax has served hundreds of clients across China and Southeast Asia (including Malaysia), helping users achieve an 80%-90% acid recovery rate, over 95% metal ion retention, and annual cost savings of approximately $24,600 per enterprise. Certified as a high-tech enterprise and compliant with ISO9001 and ISO45001 standards, Smax’s DD membrane stacks are recognized as a benchmark in industrial waste treatment.
