Chlorine tolerant RO membrane: Proven Durability for Diverse Water Sources

Chlorine tolerant RO membrane：Proven Durability for Diverse Water Sources

Chlorine tolerant RO membrane is an advanced separation material engineered to withstand high concentrations of residual chlorine without significant degradation.

Product Overview

A Chlorine tolerant RO membrane is an advanced separation material engineered to withstand high concentrations of residual chlorine without significant degradation. Unlike standard polyamide membranes that deteriorate rapidly when exposed to oxidants, these specialized membranes utilize unique polymer chemistry to maintain structural integrity.At the heart of this technology lies a robust active layer that resists chlorine attack. This innovation allows the membrane to operate effectively in water streams containing free chlorine, eliminating the need for extensive pretreatment to remove oxidants. The result is a more resilient, cost-effective solution for various industrial and municipal applications.

Working Principle

The Chlorine tolerant RO membrane operates on the principle of size exclusion and solution-diffusion, similar to conventional RO membranes. However, its chemical structure differs significantly. The membrane surface features chlorine-resistant functional groups that do not undergo the hydrolysis or chain scission commonly seen in standard membranes.When pressurized feed water passes through the membrane, water molecules permeate through the semi-permeable barrier while rejecting dissolved salts, organics, and microorganisms. The chlorine tolerance is achieved through cross-linked polymers that maintain their integrity even in oxidative environments, ensuring consistent performance over extended periods.
