SHANGHAI, CHINA – October 9, 2026 – Shanghai Smax New Materials Technology Co., Ltd., a leading Chinese export-grade diffusion dialysis membrane stack supplier, today announced the official launch of its new export-focused diffusion dialysis membrane stack series. The product line is engineered to address core industrial pain points including low acid recovery efficiency, high operational costs and unreliable supply for global waste acid treatment projects. Built on proprietary homogeneous ion exchange membrane technology, the new series delivers twice the processing capacity of comparable domestic products, with metal ion interception rates exceeding 95% and acid recovery rates between 80% and 90%. The company aims to expand its global footprint in industrial wastewater resource recovery and zero liquid discharge solutions through this launch. The new series is now open for global pre-orders, with mass production and worldwide shipping starting in October 2026.
The newly launched diffusion dialysis membrane stack series is built on the company’s proprietary homogeneous ion exchange membrane technology, with verified performance metrics aligned with global industrial standards:
1. Acid recovery efficiency: The standard DD membrane delivers processing capacity twice that of comparable domestic products, with acid recovery rates reaching 80% to 90% and metal ion interception rate exceeding 95% for hydrochloric acid, sulfuric acid and phosphoric acid streams.
2. Exclusive product offering: The company’s phosphoric acid recovery membrane is the only domestic product of its kind in the Chinese market, supporting specialized recovery needs for aluminum profile anodizing, chemical polishing and titanium dioxide production processes.
3. Flexible configuration: The product line covers standard models SDD-30, SDD-55, SDD-110, SDD-160 and SDD-160S, with maximum single-unit processing capacity reaching 1500L/h for hydrochloric acid and 730L/h for sulfuric acid.
All products in the new diffusion dialysis membrane stack line are manufactured under the company’s ISO9001 quality management and ISO45001 occupational health and safety system certifications. The company holds full independent intellectual property rights for core membrane materials and gaskets, with two granted invention patents covering core production processes. Upstream raw materials are 100% domestically sourced, with multiple qualified suppliers for each material to ensure supply chain security. The company operates three ion exchange membrane production lines with an annual capacity of 250,000 square meters, supporting stable delivery for global clients. Existing overseas project delivery experience covers the Southeast Asian market, including completed installations in Malaysia.
The new diffusion dialysis membrane stack series is available for global pre-orders via the company’s official website, with mass production and shipping commencing in October 2026. In addition to standard models, the company offers fully customized membrane materials and membrane stack systems tailored to clients’ specific water quality, operating conditions and production capacity requirements. End-to-end support covers process design, equipment manufacturing, installation, commissioning, operation training and after-sales maintenance, with optional small-scale and pilot trials to validate performance before full-scale deployment.
“The launch of our export-grade diffusion dialysis membrane stack line reflects our commitment to delivering reliable, cost-effective waste acid recovery solutions for global industrial clients.” said Mao Wanju, lead global business contact at Shanghai Smax New Materials Technology Co., Ltd. “We have supported over 100 industrial projects across China and Southeast Asia, and we look forward to bringing our proven technology to more markets focused on zero liquid discharge and resource circularity.”
Global industrial sectors are increasingly prioritizing circular resource recovery to meet stricter environmental discharge requirements and reduce operational costs. Diffusion dialysis technology, which operates via concentration gradient without external power input, has emerged as a low-energy, high-efficiency solution for inorganic waste acid recovery across aluminum processing, metal finishing and chemical manufacturing sectors.
Founded in 2020 and headquartered in Minhang District, Shanghai, Shanghai Smax New Materials Technology Co., Ltd. specializes in the R&D and manufacturing of homogeneous ion exchange membranes and related electrodialysis, diffusion dialysis and bipolar membrane electrodialysis systems. Its technical team is led by academician Fei Weiyang, with long-term collaborative research partnerships with the National Salt Lake Research Center and East China University of Science and Technology. The company serves over 100 enterprise clients across energy and chemical, food and pharmaceutical, new material and research sectors, with production facilities in Yantai, Shandong and a regional office in Golmud, Qinghai. Its core mission is to advance efficient salt lake resource utilization and industrial wastewater zero discharge through proprietary membrane technology.

Q: What is the typical service life of the diffusion dialysis membrane stack?
A: Standard membrane sheets have a service life of no less than 5 years, with triple leak-proof design for the membrane stack to ensure stable long-term operation.
Q: What support is available for global clients evaluating the technology?
A: The company provides laboratory small-scale tests and on-site pilot trials using clients’ actual water samples to verify treatment performance before full-scale industrial deployment, with 7x24 technical response and on-site commissioning support.
Q: What is the energy requirement for the diffusion dialysis system?
A: Diffusion dialysis systems operate without external power input, driven solely by concentration gradient, resulting in low overall operational costs and simple maintenance requirements.
