Nanofiltration (NF) Systems NFS 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).
NFS series nanofltration systems are pre-engineered and pre-assembled units to produce clean, purified water with nanofltration membranes for fresh groundwater and surface water. The multiple volumes can help meet your a variety of commercial applications 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.

Our 500 LPH Reverse Osmosis (RO) System is engineered to provide high-quality purified water for commercial applications. Designed with advanced RO technology, durable components, and a user-friendly interface, this system ensures consistent performance, low maintenance, and long-term reliability.
With its compact design and robust skid-mounted frame, it’s an excellent choice for businesses that demand efficiency and quality in water purification.
BWE series Reverse Osmosis (RO) systems are pre-engineered and pre-assembled units with 8” membrane housings for brackish water(higher TDS).The large volumes can help meet your a variety of industrial applications.T hey are designed for overall superior performance, high recovery rates and offer great savings with low maintenance and operation costs.
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.
AQUALITEK 12TPH Industrial UF Water Treatment Device (UFL-4 Series) delivers high-efficiency, high-throughput ultrafiltration with Automatic Backwash Technology, high fouling-resistance membrane modules for efficient pretreatment and turbidity reduction in industrial and commercial applications.
