MUNI RO LE Series
Membrane Elements for Municipal Drinking Water Plants
Engineered to treat municipal potable water at lower pressures, the MUNI RO LE series enables drinking water processes to achieve reduced operating
costs. Low-pressure operations also reduce membrane compaction, which increases the efficiency of
the RO system.
Description and Use
The MUNI RO LE series offers the unique solutionoriented 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 adhesion, and allowing for quick and complete cleaning.
In addition to this sanitizing feature, pressure drop
across the elements using Full-Fit design is significantly less than standard FRP construction (Figure
1), which may lead to substantial energy savings.

Table 1: Element Specification
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.

The element diameter (dimension C) is designed for optimum performance in GE
pressure vessels. Others pressure vessel dimension and tolerance may result in
excessive bypass and loss of capacity.
