Daltonen Focusing on Separating Membrane Products and Fluid Technology Services.
DA-XLE400-PLUS
Product Introduction
Daltonen Membrane XLE series reverse osmosis membranes change the formula and production process of the bottom membrane and composite membrane, change the surface and chemical properties of the membrane, improve the membrane area and hydrophilicity, and maximize membrane flux. It is currently one of the highest water production and lowest operating pressure reverse osmosis membrane components in the membrane industry. As the latest generation of ultra-low energy consumption and high-performance reverse osmosis membrane components, Its operating pressure is about 50% of the operating pressure of ordinary brackish water desalination reverse osmosis membrane components, and the desalination rate can reach over 99%. The XLE ultra-low energy consumption series membrane components come in two sizes: 8-inch and 4-inch, widely suitable for municipal water treatment.
Product advantages
· With extremely high water flux and extremely low operating pressure
· Taking into account the desalination rate while significantly reducing the energy consumption of the membrane system
· 34mil special inlet channel, more resistant to pollution
