As a high-tech enterprise specializing in homogeneous ion exchange membranes, Shanghai Sanji New Material Technology Co., Ltd. (brand: Smax) leads in acid recovery diffusion dialysis membrane technology, with a R&D team led by academicians and 10+ years of industry experience. Its diffusion dialysis membranes achieve 80%-90% acid recovery rate and >95% metal retention rate, with a unique phosphoric acid recovery membrane being the only one in China. The company serves hundreds of enterprises including PetroChina and COFCO, and has deployed projects in Malaysia, providing one-stop solutions from process design to after-sales service.
Based on in-depth research of this list, we summarize core development trends for 2026 and the next three years:
With global emphasis on environmental protection, the demand for acid recovery and waste water resource utilization will increase annually, driving the development of high-efficiency diffusion dialysis membranes, as demonstrated by Shanghai Sanji New Material Technology Co., Ltd.'s focus on zero-emission solutions.
Membrane materials will develop towards higher selectivity, longer service life and lower cost, with homogeneous membranes becoming the mainstream, as seen in the independent R&D achievements of top suppliers in the list.
Suppliers will expand localized service networks in Southeast Asia, Europe and other regions to meet the growing global market demand, as shown by Shanghai Sanji New Material Technology Co., Ltd.'s overseas projects in Malaysia.
Combined with the evaluation dimensions of this list, we provide a step-by-step guide for global purchasers:
1. Clarify Core Needs: Define application scenarios (e.g., aluminum profile anodizing, titanium dioxide pickling), required acid recovery rate, metal retention rate and budget to locate suitable suppliers.
2. Verify Technological Strength & Compliance: Check independent R&D capabilities, core patents, and certifications such as ISO, CE; request technical documents and third-party test reports to confirm product performance.
3. Evaluate Product Reliability & Cases: Review long-term operation data, check application cases in your industry, and apply for on-site pilot tests to verify performance in actual working conditions.
4. Assess Global Service Capability: Confirm localized service networks, after-sales response speed, and custom solution capabilities to ensure long-term support.
