Models

 Reverse osmosis (RO) and nanofiltration (NF) membrane elements can be divided into "industrial", "commercial", "residential" 3 series according to the application field.

 RO membrane has brackish water (BW), ultra-low pressure (ULP), extreme low pressure (XLP), fouling resistant (FR), sea water desalination model (SW) etc. according to its performance.

 NF membrane has high flux (NF2), high rejection (NF1), material separation model(NF-F) etc. according to its performance.

 Flat sheet membrane types：brackish water (BW), high rejection(ULP-HR)
