4 inch Low Pressure Reverse Osmosis Membranes
Low Energy (LE type) and Low Pressure (LP) membrane elements are recommended for low-moderate salinity applications or/and in applications where low energy consumption is an important consideration.
The LE and LP elements are designed with a highly efficient polyamide membrane barrier layer, providing high flow productivity combined with excellent salt rejection.
Lanxess LE and Vontron ULP membrane elements are based on 10.3 bar (150 PSI) test pressure.
Lanxess ULP and Vontron XLP membrane elements are based around 7 bar (100-110 PSI) test pressure.
