DF (Dalton Filtration) series nanofiltration membrane elements are divided into DF30 ultra-low pressure and DF90 low pressure high desalination products. DF30 is used to remove total organic carbon (TOC) and trace organic pollutants, especially has a high removal rate for emerging pollutants (PCPs, EDCs, POPs), and has high permeability to dissolved inorganic salts, featuring high organic retention and low energy consumption. DF90 can remove hardness, heavy metals, sulfate, nitrate, chloride, fluoride, effectively remove trace organic pollutants such as PCPs and EDCs as well as microorganisms such as bacteria and viruses. It has the advantages of low operating pressure, high water production and high recovery rate. DF series nanofiltration membrane products are major landmark achievements of the National "Twelfth Five-Year Plan" Water Special Project, selected into the "National Catalog of Major Environmental Protection Technology Equipment Encouraged for Development" and "Zhongguancun National Independent Innovation Demonstration Zone First Set of Major Technical Equipment Demonstration Project", and have won scientific and technological honors such as "Beijing New Technology and New Product" as well as awards such as "National Science and Technology Progress Second Prize" and "Ministry of Education Science and Technology Progress First Prize".
