SW Series -Seawater Desalination RO Membranes UC SW-8040-400HR

UltraClean SW series are high-end RO membranes featuring a supporting layer with high compression resistance, thick and dense flawless thin film layer. It has good wear and chemical degradation resistance. 

Product Description

 The membrane element does not need postprocessing during the manufacturing. It tolerates a wide range of pH, which enables more efficient and rougher cleaning using regular acid and base, therefore it has high cleaning efficiency. The membrane system can operate in long term under lower pressure due to thorough cleaning, therefore the membrane performs better during its service life. It can significantly reduce operation costs, and bring the best long-term economy to the seawater desalination system.

Membrane Features

Advanced membrane technology with innovative thin layer composite membrane design.

More consistent performance with less fouling requiring less frequent cleaning and change-outs.

100% dry-stored membrane maximizing shelf life.

Products Highlight

High rejection rate of salts

High compression and fouling resistance and high cleaning efficiency

Cost-saving of seawater desalination system

General Information

The first full tank of permeate should be discarded, DO NOT use this initial permeate for drinking water or food preparation.

Keep membrane moist at all times after initial wetting.

To stop growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution.
