INTRODUCTION
Residential reverse osmosis membrane elements are rolled with ultra-low pressure aromatic polyamide composite reverse osmosis membrane flat sheets.
The membranes are suitable for treatment of raw water with salinity less than 1000mg/L. It has the characteristics of high rejection rate and low operating pressure. It is mainly used in small direct drinking water devices at home or office. The product meets the water efficiency requirements of grade 2 and above in the "Restricted Value and Water Efficiency Grade of Reverse Osmosis Water Purifiers" in GB34914-2021.
