Nanofiltration (NF) Systems NFL Series

Nanofiltration is a speciality membrane process which rejects particles in the approximate size range of 1 nanometer. It reliably remove color and total organic carbon (TOC) from surface water, hardness or radium from well water, overall reduce total dissolved solids (TDS).

NFL series nanofltration systems are pre-engineered and pre-assembled units to produce clean, purified water with 8” nanofltration membranes for fresh groundwater and surface water. The multiple volumes can help meet your a variety of industrial such as drinking water treatment. They are designed for remove a high percentage of TOC and THM precursors while having a medium to high salt passage; medium hardness passage.

Multi-Layer Media Filter (Anthracite & Sand) for Iron & Sediment Removal

Multi-Media Filter (MMF)

Our Multi-Media Filter (MMF) is a highly efficient water filtration system designed to remove suspended solids, turbidity, and other impurities from water. Unlike single-media filters, MMFs use multiple layers of filtration media—such as sand, anthracite, and gravel—each with varying sizes and densities.

This layered structure allows for superior filtration, increased dirt-holding capacity, and longer operational cycles.

Multi-Media Filters are widely used in industrial, municipal, and commercial water treatment applications, serving as a crucial pre-treatment step for processes like reverse osmosis (RO) and ultrafiltration (UF). By ensuring cleaner water and reducing maintenance needs, MMFs enhance the overall efficiency of water treatment systems.
