Nanjing ruijiete Membrane Separation Technology Co., Ltd., established in 2010, focuses on the research and manufacturing of core modules of membrane bioreactor (MBR). It is the first environmental protection technology company in the industry to practice the "environmental protection + Internet" model. Its business includes "ruijiete MBR membrane products" and "environmental protection hydrosphere".

Ruijiete MBR membrane products are used to provide scientific membrane water treatment solutions for environmental protection engineering companies. In 2010, the first double stacked flat membrane was at the international leading level, and multi-channel flat membrane and high-density flat membrane were developed at the same time; In particular, the MBR membrane tank put into development in 2018 has led the transformation of integrated and integrated environmental protection equipment to standardization, and 33 patents have been applied for (including 7 invention patents).

By the end of 2018, the market share of flat membrane products has reached 20%, ranking in the forefront of the industry. There are about 1000 successful projects in 30 regions across the country, covering more than 20 industries, including slaughtering wastewater, aquaculture wastewater, black and smelly river sewage, upgrading and reconstruction of urban sewage treatment plants, high concentration and refractory industrial wastewater, landfill leachate and slightly polluted water, including more than 400 in Jiangsu Province.
