Daltonen Focusing on Separating Membrane Products and Fluid Technology Services.
DA-LE400-PLUS
Product Introduction
The Daltonen Membrane LE series reverse osmosis membrane components change the density and surface characteristics of the membrane by changing the formula and production process of the bottom membrane and composite membrane. Compared with traditional brackish water membrane components, it provides a desalination rate of over 99.3% while reducing operating pressure by about 33%. The LE low-power series membrane components come in two sizes, 8-inch and 4-inch, and are widely used in surface water and tap water sources.
Product advantages
· Can effectively reduce the operating pressure and energy consumption of the membrane system
· Has stable desalination rate and water yield
· The membrane system operates economically well
· 34mil special inlet channel, more resistant to pollution
