On August 30, the Research and Application of Anti-fouling Reverse Osmosis Membrane Components, a project developed by CHN Energy, successfully passed the scientific and technological achievement appraisal organized by the China Membrane Industry Association. Experts of the assessment group agreed that the main performance indicators of the anti-fouling reverse osmosis membrane components have reached an internationally leading level.

This technological breakthrough addresses problems such as membrane performance decline, complex maintenance, and short lifespan caused by reverse osmosis membrane fouling. Through the optimized design of structures like the brine spacer, freshwater channel, permeate tube, and membrane element end caps, CHN Energy developed anti-fouling reverse osmosis membrane components, reducing membrane fouling during operation. Third-party professional testing showed that, under pollution conditions over a six-month period, the product’s salt rejection rate only decreased by 0.4%, and water flux by just 10.9%, demonstrating strong anti-fouling capabilities.

The anti-fouling reverse osmosis membrane components feature innovations in structural design and intelligent manufacturing, with five patent applications filed, one patent granted, and one standard compiled. The product has already been applied in more than 30 companies across CHN Energy’s power, coal, and chemical sectors, reducing reverse osmosis membrane procurement costs by about 30%. Those companies have all given positive feedback on its performance, and its application has created significant economic and social benefits.
