DA-FRLE400-ADD


Product Introduction

Daltonen Membrane FRLE series reverse osmosis membrane components have strong anti pollution performance and low energy consumption performance, and are developed for treating highly biologically or organically polluted water sources. Its operating pressure is about 30% lower than that of ordinary reverse osmosis membrane components for desalination of brackish water, and the stable desalination rate can reach over 99.3%. The FRLE anti pollution and low energy consumption series membrane components come in two sizes: 8-inch and 4-inch, suitable for municipal water treatment.

 

Product advantages

· It can effectively reduce the energy consumption of membrane system operation and improve the economic efficiency of system operation

· Good pollution resistance and high pollution influent water quality

· 35mil special inlet channel, more resistant to pollution
