Microfiltration (MF) is generally defined as a membrane separation process using membranes with pore sizes between approximately 50 to 10,000 nanometers, a molecular weight cut-off (MWCO) greater than 1,000,000 Daltons and relatively low operating pressures. Materials retained by MF include sand, silt, clays, yeast, algae, and bacteria. Therefore our MF membranes are very suitable solutions for the Food & Beverage industry.

Although our MF hollow fiber membranes can be used as (pre-)treatment of potable water or cold sterile filtration, nowadays its main success is in the clarification of beverages like wine and cider, and in the filtration of beer. This method of membrane filtration is a replacement of diatomaceous earth (kieselguhr). Other applications are the clarification and purification of cell broths, sterile filtration of dairy or the separation of casein and whey proteins.

Our products

The NX Filtration Microfiltration membrane material is hydrophilic PolyEtherSulfone (PES), which has a good chemical stability for the use in robust processes. High performance plastics are used for our membranes and modules in order to achieve a sanitary design meeting the Food & Beverage requirements. Our products are typically cleaned with conformable concentrations of lye, acid or oxidizing agents. The range of pore sizes we offer is between 50 to 500 nanometers.
