Our membranes and filter devices are engineered for microfiltration and ultrafiltration of liquids. They can be used in a cross-flow or a dead-end mode.
Cross-Flow Filtration using Liqui-Flux® Liquid Filtration Products
In cross-flow filtration, a fluid stream runs tangential to the membrane. A pressure differential is established across the membrane, which causes some of the smaller particles to pass through the membrane. Remaining particles that are larger than the membrane pore will continue to flow across the membrane, in essence “cleaning it”. In contrast to the dead-end filtration technique, using a tangential flow path will prevent thicker particles from building up a ‘filter cake’ on the membrane surface.
Dead-End Filtration using Liqui-Flux® Liquid Filtration Products
In dead-end filtration, all of the liquid travels through the membrane. Any particles that are larger than the membrane pore will be retained on the upstream side of the membrane and they will form a filter cake on the membrane surface. This built-up layer can later be cleaned off of the surface.
