Fact Sheet
MUNI RO HR LE Series
Reverse Osmosis High Rejection Low Energy Membrane
Elements for Municipal Drinking Water Plants
Engineered to treat municipal potable water at low-
er pressures, the MUNI RO HR LE series enables
drinking water processes to achieve reduced oper-
ating costs while maintaining a high level of salt
rejection.
MUNI RO HR LE series membrane elements are the
solution for purification of drinking water that pro-
vide the benefits of both high rejection and low en-
ergy consumption.
MUNI RO HR LE elements feature a FRP outer wrap
and female end connections and are tested and
certified by NSF international against NSF/ANSI
Standard 61 for material requirements only.
