Title: Shanghai Sanji Releases China’s First Domestic Phosphoric Acid Recovery Diffusion Dialysis Membrane

Shanghai, China, 16th Jul 2026 - Shanghai Sanji New Material Technology Co., Ltd.has officially launched China’s first domestically produced phosphoric acid recovery membrane, alongside a full lineup of diffusion dialysis membrane solutions for industrial waste acid treatment. The self-developed membrane series features zero electricity consumption, 80–90% free acid recovery efficiency, and over 95% metal ion rejection performance. Engineered for aluminum anodizing, titanium dioxide pigment production and stainless steel pickling industries, the new products address rising zero-liquid-discharge compliance demands for China’s low-carbon industrial transformation. The localized membrane portfolio fills a long-standing domestic supply chain gap that previously relied entirely on imported phosphoric acid recovery membranes, offering cost-effective, maintenance-free industrial wastewater recycling alternatives.Core Product Series and Technical PerformanceShanghai Sanji’s 3 major diffusion dialysis membrane series adopt homogeneous ion exchange membrane technology, featuring uniform surface functional group distribution and low membrane resistance to ensure stable, long-term separation performance in harsh industrial acid waste environments.DD Series – General Acid Recovery MembraneThe DD series targets hydrochloric acid and sulfuric acid wastewater, the most common waste acid types in metal processing industries. With a membrane thickness of 90–120 μm, membrane resistance of 0.8–1.3 Ω·cm² and ion exchange capacity of 1.5–2.3 meq/g, the series maintains 80–90% free acid recovery and over 95% metal ion rejection. Driven solely by solution concentration differentials, the zero-power membrane system supports stable continuous operation for more than 8,000 hours annually. A singl...
