Removing natural organic matter from source water with HFNF
Remove colour and natural organic matter sustainably. NX Filtration’s HFNF membranes deliver >95 % colour & TOC removal at feed up to 80 mg C/L—chemical-free and energy-efficient.
Struggling with natural organic matter in your source water?
Surface waters often carry humic acids and other natural organic matter (NOM) that create unwanted colour and increase disinfection by-product potential. NX Filtration’s Hollow Fiber Nanofiltration (HFNF) delivers a chemical-free, low-energy solution—removing colour and total organic carbon (TOC) to exceptional levels while keeping your process simple and sustainable.
Proven performance for colour and TOC reduction, even under challenging source-water conditions.
Chemical-free treatment
No coagulants, no sludge handling, and no added salts or anions that raise corrosion index.
Energy-efficient operation
Sustainable low-pressure process of ~0.2 kWh/m³.
Compact & easy to integrate
Small footprint and straightforward automation for both retrofits and new builds.
Scalable design
From decentralized installations to large municipal plants.
HFNF tackles the toughest organics — humic acids and natural organic matter — that drive colour, taste, and disinfection by-product formation. By removing >95% of colour and TOC without coagulants or sludge, utilities can reliably produce safe, stable drinking water even from difficult surface or groundwater sources.
Industrial and reuse applications
HFNF is proven on demanding industrial waters with high COD or colour loads, reducing chemicals, energy use, and overall treatment costs. Where project water quality requires it, HFNF can also serve as an effective pretreatment step for RO, consistently delivering low-fouling feedwater (SDI < 3) and protecting downstream membranes.
Proven Worldwide – From Lab to Full Scale
Seeing is believing. NX Filtration demonstrates HFNF performance across the globe—from bench tests to full-scale installations—delivering clean, colour-free water with lower energy use and minimal waste.
