1. Dow Jones index

Dow is one of the earliest companies to develop reverse osmosis membranes, with numerous patents and comprehensive product lines. After the merger of 20 15 and DuPont, the reverse osmosis membrane businesses of DuPont and Dow were integrated, all under the brand of FILMTEC, and its company became the second largest chemical plant in the world. However, at present, the supply to China is limited, and it is rare to buy real goods in China, and the price is also expensive.

2. Toray, Japan

Toray was founded in 1926 and was one of the earliest companies to develop reverse osmosis membranes. After decades of precipitation, its product lines are numerous. At present, Han Shi also belongs to Dongli Group!

3。 Korean CSM Han Shi

The membrane produced in Han Shi has the characteristics of high stability, high temperature resistance and acid and alkali corrosion resistance. The reverse osmosis membrane of the World Bank has high degree of automation, simple operation, convenient maintenance and safe and stable operation. There is no need to add any chemical additives in sewage filtration treatment to avoid secondary pollution of water body. The membrane flux is large, especially in urban drinking water treatment, and the application efficiency is high. In addition to reverse osmosis, it also involves ultrafiltration, household water purifier, water treatment engineering and other businesses. Han Shi is also an earlier imported membrane brand in China. 1993, Han Shi established a branch in China, East Aike Membrane Technology (Tianjin) Co., Ltd.

In 20 17 years, major brands are still in the era of 1: 1. Han Shi took the lead in developing the patented pure water protective film 3: 1 micro-wastewater system with the patent number of 20 1720443824.5. At that time, there was no first-class water efficiency standard, and Han Shi had taken the lead in entering the era of micro-wastewater without sacrificing membrane. Up to now, the reverse osmosis membrane of the first batch of users for 5 years is still in use!

20 18 reverse osmosis membrane element won the first batch of A+ water-saving certification products from cclc, and the 2065 438+09 GWPS global water purification market summit won the outstanding core award!

4. American Hyde Energy Company

Hyde Energy USA was founded in 1963, and was acquired by NEC in 1987, becoming a member of Nitto Global Membrane Division (GMD). Hyde energy water treatment membrane elements are very comprehensive, involving reverse osmosis, nanofiltration, ultrafiltration and microfiltration.

5。 Time Wharton

Time Wharton is a domestic reverse osmosis membrane enterprise with good quality. Has been committed to the research and manufacture of reverse osmosis membrane, ultrafiltration membrane, nanofiltration membrane and other products. Have independent core intellectual property rights.
