Ultrafiltration is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. This separation process is used in industry and research for purifying and concentrating macromolecular solutions, especially protein solutions.
Ultrafiltration is not fundamentally different from reverse osmosis, microfiltration or nanofiltration, except in terms of the size of the molecules it retains.
The usage of filtration is expansive and ranges from;
Protection against bacteria like Legionella in drinking water systems in for example hospitals, hotels swimming pools and nursing homes.
Filter systems for process water, flush water, surface water or water for the food and beverage industry. A good example is the wine industry; Based on a specially pore size we filter particles out of wine to create a top product in which flavours, fragrances and colour are protected.
