Ultra Low Pressure RO Element

Ultra Low Pressure RO Element is developed for treatment of surface water and underground water. Its operation pressure is about 2/3 of low pressure membrane, and the rejection rate can reach 99.5%.Thus it can reduce the investment cost of related pumps, pipelines, containers and other equipment and the operation cost of RO system, improve economic benefits.Ultra Low Pressure RO Element has low operating pressure, large water production, high desalination and desiliconization rates, saving system operating costs and equipment investment, and has good chemical stability.

SKU: N/A Category:
