CM Ultra Extreme Low Pressure (XLE) Series RO Membrane Elements
Product Features
XLE series membrane module is a reverse osmosis membrane product for TDS≤500mg/L water quality purification, with a high salt rejection rate and water flux under extremely low operating pressure, which can save a lot of energy, so that the user's water equipment investment cost and operating costs are greatly reduced. The product can be applied to the purification of municipal tap water, rainwater, surface water of rivers and lakes and other similar water sources.
