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.

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.
A water softener is a specialized filtration system designed to remove hardness-causing minerals, primarily calcium and magnesium, from water. Hard water can lead to scale buildup in pipes, appliances, and fixtures, reducing their efficiency and lifespan. By using an ion exchange process, water softeners replace these hardness minerals with sodium or potassium ions, effectively softening the water.
Water softeners are widely used in residential, commercial, and industrial applications to improve water quality, enhance appliance performance, and prevent plumbing issues. Softened water also provides benefits such as better lathering of soaps and detergents, reduced soap scum, and improved efficiency of water heaters and other appliances. With their ability to extend the life of plumbing systems and reduce maintenance costs, water softeners are an essential solution for managing hard water problems effectively.
A Water Deionizer is a specialized water purification system designed to remove dissolved ions, minerals, and contaminants from water through an ion exchange process. It effectively eliminates both cations (such as calcium, magnesium, sodium, and iron) and anions (such as chloride, sulfate, nitrate, and bicarbonate), resulting in high-purity deionized (DI) water.
Our Two Bed Deionized System is a reliable and cost-effective water treatment solution designed to produce high purity demineralized water. Using separate cation exchange resin and anion exchange resin columns, the system effectively removes dissolved salts, minerals, and impurities from raw water.
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.
