Beijing OriginWater Membrane Technology Co., Ltd. was founded in 2001 and is a part of CCCC Group. The company is located in Huairou Science Park, Beijing. Integrated with top-ranking R&D team, cutting-edge experimental instruments, advanced automatic production equipment, the company is dedicated in R&D, production and sales of reverse osmosis, nanofiltration membrane products and membrane manufacturing systems and providing overall solutions for "remediation of the water environment, development of new water sources, protection of drinking water safety and urban ecological environment construction" through membrane technology.
Now, Beijing OriginWater Membrane is equiped with 70 lines for hollow fiber membranes (MF & UF), 2 lines for corrugated membranes (MF), 8 casting & coating lines of nanofiltration and reverse osmosis (NF/RO). We also do the automatic rolling of domestic and industrial spiral wound membrane elements, assembly hollow fiber modules and units, water treatment systems and domestic and commercial water purifiers.
We started our business in MBR and take about 70% of Chinese market. The first big scale MBR in China lauched in 2006 was done by Beijing OriginWater, and there are thousands of projects scattered in China ever since. Now we are more dedicated than before in the development of overseas market.
