Product Features

LP membrane module is a reverse osmosis membrane product designed for influent TDS≤2000mg/L groundwater and lightly polluted industrial wastewater advanced treatment and other application scenarios, with a wide range of water quality adaptation and operating pressure application, and still maintain a very high water flux performance under the condition of high salt rejection rate. Products can be used in municipal water desalination, electronic ultrapure water preparation, boiler make-up water treatment and reclaimed water regeneration and other fields.
