Direct Nanofiltration

Our Direct Nanofiltration (dNF) membranes offer the unique combination of a low fouling hollow fiber configuration with the ability to remove organics and salinity (hardness) from water in one simple step. Other than a strainer, 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.

Ultrafiltration

Our Ultrafiltration (UF) membranes are the best choice for retaining micro-organisms, yeast and suspended particles, while salts, proteins and smaller organic molecules can pass the membrane. Our UF membranes are based on modified PES chemistry resulting in excellent chlorine tolerance and pH stability. The membranes are operated ‘inside-out’, in semi dead-end or cross-flow mode, providing perfect control of the membrane fouling rate.

Microfiltration

Our unique and high-end microfiltration membranes are ideally suited for the clarification of beverages, such as beer and wine, as well as for dairy, biotechnology and pharmaceutical applications. The MF membranes are designed to remove larger constituents from any fluid stream via size exclusion. MF offers an superior alternative for traditional filtration methods (kieselguhr, diatomaceous earth) because of its higher and more constant quality, lower energy use and the possibility of continuous operation. The NX Filtration MF membrane material is hydrophilic PolyEtherSulfone (PES), which has an excellent chemical stability for the use in robust processes.

Pilots and Test Stations

For selecting the best membranes for your application and for optimal system design we offer digital modeling, lab-scale testing and piloting services. A wide range of units exist from a portable lab-scale unit up to a fully automated unit with up to 10 full scale membranes. Expert support is also provided during pilot trials.
