Product Introduction

Product Description:

Membrane Material: Polypiperazine

Outer Wrapping Type: Fiberglass Reinforced Plastic (FRP) Wrapping

Flow Channel Type: Parallel Flow Channel 34mil/46mil, customizable to other sizes

Membrane Welding Method: Multi-page/Short-page Welding, Lower Salt Permeation Rate

Application Scenarios: Leachate Decolorization, Dye Decolorization, Chlor-Alkali Denitration, Wastewater Salt Separation, etc.

Product Advantages:

Utilizes imported membrane sheets combined with proprietary modification patents to eliminate microscopic surface defects, enhancing anti-fouling performance and balancing flux/desalination rate;

Employs parallel flow channel design, which eliminates dead zones, offering more thorough cleaning compared to diamond-shaped flow channels, reducing crystal adhesion and providing excellent performance recovery;

Uses multi-page/short-page welding to increase the utilization rate of effective membrane area, reduce dead zones, and enhance water production flux;

Incorporates special sealing adhesive to reduce salt permeation at the seal under high-pressure conditions, improving overall saltwater rejection performance.
