Cross-Flow Filtration

Crystar® crossflow filtration components comprises tubular components fabricated from multiple layers of recrystallized silicon carbide. They have the most permeable carriers on the market, which enables high permeate transfer and very effective backwash or back flush operations. They are certified for food contact according to EU regulation 1935-2004.

• Crossflow filtration uses a selective porous membrane that filters highly loaded liquids for purification or clarification. Tubular crossflow filters have been used for the clarification of wine, along with the filtration of dairy, fruit juices and water, for chemical recovery and for the treatment of challenging industrial effluents.

• Crossflow filtration gets its name because the majority of the feed flow travels longitudinally along the surface of the filter channels, whereas the filtered permeate flows radially through the carrier porosity. The structure of the traditional crossflow filters is tubular and consists of a carrier that is the base material, and on top of it is the filtration membrane, which is a thin, porous layer applied on the carrier.

The efficiency of crossflow filtration technology to treat highly loaded and high fouling streams, makes it widely used in industries around the globe. Crystar® FT ceramic membranes are the next generation of ceramic microfiltration.
