FR Series and PURO Series: Fouling Resistant RO Element

 

Brief Introduction

FR series of fouling resistant aromatic polyamide composite membrane element is developed by VONTRON for complex water quality. FR series element with special membrane preparation process, it improved the hydrophilicity, charge characteristic and roughness, can effectively reduce the breeding of biofouling and adsorption of pollutants in the membrane surface. The element is applied a special 34 mil spacer design, which effectively reduced fouling and pressure drop, with more durable on cleaning can extent the service life.

 

PURO series is upgraded fouling resistant RO element. On the basis of FR series, it increased the degree of polymerization of aromatic polyamides and the thickness of separation layer. Meanwhile, a special 34 mil channel design is adopted, which further increased the rejection rate, reduces the pressure drop and enhances the firmness of element during cleaning.

 

PURO-LE is an energy-saving fouling resistant RO element. Under the same conditions, the operating pressure can be reduced by more than 25% to achieve energy saving.

Scope of Application

FR series and PURO Series of fouling resistant membranes normally suitable for treatment of complex water source with TDS less than 10000 ppm. It is mainly used for purification of surface water, mining waste water, municipal reclaimed water, industrial waste water, RO brackish water, etc.
