Hollow Fiber Nanofiltration membranes
Worldwide unique nanofiltration concept, designed to remove microplastics, pesticides, pharmaceuticals, and color from (waste) water
Our Hollow Fiber Nanofiltration (HFNF) membranes offer the unique combination of a low fouling hollow fiber configuration with the ability to remove organics and salinity (hardness) from water. Other than a strainer or sand filtration, no further pre-treatment is required. We manufacture our membranes with a patented layer-by-layer process, where multiple nano-scale layers are deposited on a membrane support. This method enables very precise and controlled rejection and flux properties of the membrane. A unique solution for troubled water.
Applications
Our HFNF membranes are the solution for color removal, COD/BOD removal, reclamation of cleaning solutions or coloring dye from water. Creating potable water directly from surface water, reclaiming industrial waste water, or removing medicine residues, microplastics and endocrine disruptors from waste water are areas where NX Filtration’s dNF membranes excel.
Product specifications
Our HFNF modules provide an open, low fouling construction without obstruction by spacers as mostly used in other nanofiltration membranes. In addition, dNF modules can be backwashed. The robust chemistry allows continuous operation. Cleaning with chlorine and at very high or low pH are possible. Due to this chlorine tolerance, biofouling can be controlled for high fouling applications.
Projection Tool
NX Filtration Projection Tool is an intuitive, online platform that enables the rapid and iterative system design for our HFNF membranes and provides an estimation of the rejection of key components like TOC (Total Organic Carbon), COD (Chemical Oxygen Demand), BOD (Biological Oxygen Demand) and ion composition in the permeate and concentrate streams. Furthermore, it provides an estimation of rejections of several micropollutants, including PFAS, as well as other organic molecules.
