Product Introduction

The Daltonen Membrane XFR series reverse osmosis membranes are manufactured using the latest membrane preparation technology, utilizing different reaction conditions and post-treatment to change the charge and smoothness of the membrane surface, increase the hydrophilicity of the membrane surface, reduce the adhesion of pollutants and microorganisms on the membrane surface, and have stronger anti scaling performance, thereby extending its service life. The raw water that can effectively purify biological and organic pollutants provides excellent products for the difficult water treatment industry. The XFR ultra anti pollution series membrane components come in two sizes: 8-inch and 4-inch.


Product advantages

· Has strong anti pollution performance and long service life

· High durability

· High removal rate and high water yield

· 35mil special inlet channel, more resistant to pollution
