DA-FR400-PRO


Product Introduction

Daltonen Membrane FR series reverse osmosis membrane components use special composite membrane preparation technology to change the charge and smoothness of the membrane surface, enhance the hydrophilicity of the membrane surface, reduce the adhesion of pollutants on the surface, and have strong anti scaling and anti pollution performance. The use of a short membrane structure to increase the number of membrane pages greatly improves the efficiency of membrane use. The FR anti pollution series membrane components come in two sizes: 8-inch and 4-inch, mainly used for treating water sources with high organic and biological pollution, such as smelting wastewater, printing and dyeing wastewater, and industrial wastewater from thermal power plants.

 

Product advantages

· Has strong anti pollution performance and long service life

· Suitable for membrane treatment systems with poor inlet water quality

· 35mil special inlet channel, more resistant to pollution
