Energy-Efficient Low Pressure RO Membranes for Reliable Water Purification
JRW series low-pressure reverse osmosis membrane elements are divided into high desalination and high flux series. JRW series membrane elements are suitable for desalination treatment of surface water, groundwater, and some low-pollution water sources with feed water salinity below 1500ppm. They are mainly used for low-salinity applications such as municipal landscaping and agricultural irrigation , drinking water supply, drainage, and greywater treatment ; pharmaceutical pure water and secondary treatment in reverse osmosis systems; commercial pure water machines, hospital and laboratory pure water systems, and integrated water purifiers. Operating under ultra-low pressure, they feature high flux and low energy consumption. In particular, the JRW-4040-HF membrane element, under normal feed water conditions, can achieve the same water output (1 ton of water/h) with 3 JOZZON membranes as other manufacturers’ 4 membranes. This significantly reduces the system’s footprint and energy consumption, lowering the economic cost for users while maintaining performance.
