NX Filtration specializes in hollow fiber nanofiltration (HFNF) membrane technology, designed to remove micropollutants—including pharmaceuticals, PFAS, insecticides—as well as colour, selective salts, bacteria, viruses, and nano plastics in a single filtration step. This technology reduces the need for extensive pre-treatment and chemical usage, making it a more sustainable solution for water treatment.
NX Filtration’s membrane modules are used in two main applications; Clean Municipal Water – Treating surface water for safe drinking water production and Sustainable Industrial Water – Supporting industries in water treatment, pollutant reduction, and water reuse.
As a long-time partner of NX Filtration, EMI Twente provides specialized membrane characterization to help improve performance and understanding of hollow fiber membranes. Some analyses require advanced equipment and expertise beyond standard laboratory capabilities.
Collaborating with EMI Twente allows us to gain deeper insights into our hollow fiber membranes. Their advanced characterization techniques, such as MWCO determination and FE-SEM imaging, provide valuable data that help us further optimize our nanofiltration technology.

For this project, we conducted Molecular Weight Cut-Off (MWCO) measurement to determine the precise MWCO of NX Filtration’s hollow fibers, providing key insights into separation performance. Additionally, we performed FE-SEM Imaging using our Field Emission Scanning Electron Microscopy (FE-SEM) to examine membrane structures at the nanoscale, offering a detailed view of fiber morphology. These analyses provide NX Filtration with valuable data to further optimize their processes and continue developing high-performance nanofiltration membranes for clean water.
