2017year11month3day，US joint venture in Hebei Kang Yi Long Membrane Technology Co., Ltd. signing ceremony was held at the Baoding Power Valley。Hebei Delong Environmental Engineering Co., Ltd. (hereinafter referred to as“Delong environment”) And the United StatesEconoPure Water System LLC(Hereinafter referred to as“EPthe company”），Combine their industry、Technical advantages，Create a joint venture company Kang Yi Long membrane technology，Applications to expand the low-pollution technologies Nanofiltration，China has taken a beachhead、Nanofiltration outside the key step in the production of market。Deputy director of the National Management Committee Baoding high open area Baiji Wei、Deputy director of the Baoding Development and Reform Commission Maosu Yu、CMC director of China Merchants National Baoding high open area Sun Jing、President of China International Environmental Foundation、CPPCC invited overseas on behalf of Dr. Ping He、United StatesEPPresidentDaniel Bertram、Delong environment chairman Huangde Xi and other leaders and guests invited to attend and speeches。

Low pollution nanofiltration membrane technology，It used not only for separation between the different molecular weight organics，It can also be used for desalination、Softening process，Very suitable for the current management of water pollution、Zero emissions。At present, the main control technology in the United States and Western countries，China has not mature professional manufacturer。Delong Environment and the United StatesEPThe company is a cooperative project on the basis of existing applications with domestic and international research on membrane technology system，For domestic water pollution and water shortage status quo，Especially for the conditions under strategic development of Beijing, Tianjin and integration，Pollution Situation of Water Resources Beijing, Tianjin and generally face，International patent technology，Joint development in the country to produce a low pollution、Easy operation、Low operating costs of the new nanofiltration membrane separation system。

Project to develop the nanofiltration technology products will have the following characteristics：First, strong anti-pollution film、Long-life membrane，Therefore reducing the maintenance cost of replacing the membrane element；Second, low NF newly developed low-pollution system operating pressure、Low energy consumption，Cleaning Frequency Low，Thereby reducing the overall membrane system operation and maintenance costs。The technology in the industry、Municipal and other applications on a wide range of，Especially in the current domestic sewage treatment DiBiao transformation、Zero discharge of industrial wastewater、Construction and other aspects of drinking water has a very large market prospects。The Delong environmental introduce internationally advanced technology in the construction of low-pollution Baoding nanofiltration membrane and the entire system integrated manufacturing base，Domestic water environment is bound to play an important role in governance，Make a new contribution to the blue sky of the motherland。
