Shanghai SINAP Membrane Technology Co., Ltd. is a global leader of membrane material innovation and premium manufacturer of submerged MBR flat sheet membrane elements and modules for municipal and industrial wastewater treatment applications. Shanghai SINAP was established in 2008, originally part of the Shanghai Institute of Applied Physics of Chinese Academy of Science.
We are a membrane technology pioneer in the world with 45 years UF membrane research experience and 30 patents. Shanghai SINAP produces the PVDF 0.1 µm membrane material with our own propriety technology, which has a unique asymmetric membrane structure and selective filtering mechanism. The membrane elements made of this incomparable membrane material deliver better clogging resistance, lower flux reduction rate, and longer operation stability during wastewater treatment application.
For over 20 years, the Shanghai SINAP premium flat sheet membrane elements and modules have been used in 60 countries across North America, Europe, and Asia. Together with our business partners around the world, we have successfully completed over 400 wastewater treatment projects, both in municipal and industrial applications, and earned credibility and reputation in the MBR wastewater treatment industry. We are proud to be one of the contributors in the wastewater treatment industry and continue to provide the submerged flat sheet membrane MBR solution to the global water scarcity and sustainability concerns.
Flat sheet membrane elements are made formed by membrane, support layer, guide panel, and a nozzle set on the top of guide panel. It is the core component of the MBR. See typical type and size below, other specifications available per request.

SINAP makes mini modules, small modules, double deck modules, and large modules. Other specifications available per request.
With 45 years’ R&D experience, SINAP makes membranes of different polymer material and pore size for MBR wastewater treatment, water treatment, and other applications. Shanghai SINAP produces the PVDF 0.1 µm membrane materials with own propriety technology. The SINAP membrane has a unique asymmetric membrane structure, creating a selective filtering mechanism and allowing small size particles to easily pass through but blocking the larger size particles on the membrane surface. The flat sheet membrane elements made of this membrane deliver better clogging resistance, lower flux reduction rate, and longer operation stability in MBR wastewater treatment applications.
