Industrial Water Equipment RO membrane elements include high desalination series and high flow series. RW series are suitable for desalination of surface water, underground water and low pollution water source with TDS＜1500ppm. RW series are mainly applied for municipal landscape and agricultural irrigation, drinking water treatment, municipal water supply, dewatering and reclaimed water treatment, water purification system in pharmaceuticals industry, business water purifier, water purifier system in hospital and laboratory and integrated water purifier with the advantages of lower operation pressure, higher flow and lower energy consumption.
