Homeuse RO Reverse Osmosis Membrane
Domestic reverse osmosis membrane, 1812 series and 2012 series residential membrane elements are mainly applicable to various small sized systems, such as household water purifier and other water purifying devices in hospital and laboratory. Membranes can work under ultra low pressure to reach as high permeate flow and salt rejection as regular low pressure compo--site membrane, and achieves a salt rejection rate of up to at least 97%, which can decrease the investment costs for such relevant facilities as pump, piping, and container etc., and operating cost for the RO system, thus increasing the economic efficiency.
