Fact Sheet
MUNI RO LE Series
Membrane Elements for Municipal Drinking Water Plants
Engineered to treat municipal potable water at low-
er pressures, the MUNI RO LE series enables drink-
ing water processes to achieve reduced operating
costs. Low-pressure operations also reduce mem-
brane compaction, which increases the efficiency of
the RO system.
Description and Use
The MUNI RO LE series offers the unique solution-
oriented option of a 400 sq. ft. Full-Fit* membrane
element. The creative Full-Fit design forms a close
fit within the pressure vessel walls, thus eliminating
dead spaces prone to bacterial growth and adhe-
sion, and allowing for quick and complete cleaning.
In addition to this sanitizing feature, pressure drop
across the elements using Full-Fit design is signifi-
cantly less than standard FRP construction (Figure
1), which may lead to substantial energy savings.
The MUNI RO LE membrane elements are tested
and certified by NSF international against NSF/ANSI
Standard 61 for material requirements only.
The MUNI RO LE membrane is a low energy element
following a 100% Wet Test Quality Assurance.
