2540 800GPD Reverse Osmosis Membrane

2540 800GPD Reverse Osmosis Membrane


SKU: N/A Category:


It operates under approximately two thirds of the operating pressure of regular low-pressure composite membranes, and achieves a salt rejection rate up to 99.5%, which can decrease the investment costs for such relevant facilities as pumps, pipelines, and containers, etc. and the operating cost for the RO system, thus increasing the economic efficiency.

Being suitable for the desalting treatment of those water sources with salt concentration lower than 2000 ppm, such as surface water, underground water, tap water and municipal water, membrane elements are mainly applicable to numerous applications of various scales, such as pure water, boiler water replenishment, foodstuff processing, and pharmaceutical production.
