Chengdu Nainuo MembraneTechnology Co., Ltd.
About
Hangzhou Nainuo Membrane Environmental Technology Co., Ltd. is a Chinese high-tech enterprise and the exclusive authorized distributor of the UK NANO-SEPMER brand in China, specializing in the research, development, and manufacturing of advanced separation membrane elements and integrated treatment systems. Operating from its 4,800-square-meter production facility in Hangzhou's Qiantang district with a phase-one investment of 30 million RMB, the company holds over 40 invention and utility model patents and has completed more than 200 field engineering applications. The product portfolio is organized across six membrane technology platforms: high-temperature resistant membranes including HT-RO, HT-NF, and HT-UF elements plus heat-disinfection RO membranes for pharmaceutical and food applications; acid-resistant high-pressure membranes including acid-resistant RO and NF elements for acid waste recovery; DTRO disc-tube reverse osmosis and STRO screen-type reverse osmosis membrane elements and integrated systems for landfill leachate treatment and zero-liquid-discharge applications; PTFE-MBR submerged ultrafiltration membranes and tubular UF membranes for biological wastewater treatment and high-solids streams; solvent-resistant membranes for chemical and pharmaceutical solvent recovery; and specialty membranes including anti-fouling RO, high-desalination RO, sanitary RO and NF for food-grade and pharmaceutical-grade water production, and electrophoretic paint UF membranes for paint recovery. Integrated system offerings include DTRO and STRO membrane systems, seawater desalination systems, NF drinking water systems, food-grade ultrapure water systems, hospital pure water systems, and containerized RO systems for mobile deployment. The company operates two subsidiaries: Haining Jingsipu Technology for PTFE-MBR production and Qidou Water Treatment Foshan for public water purification equipment R&D. Application fields span municipal water upgrade, industrial and park water reuse, landfill leachate full-quantity treatment, near-zero liquid discharge, sulfuric and phosphoric acid recovery, electrophoretic paint recovery, and biopharmaceutical separation and concentration processes.
