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 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 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, 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.
