This intends to combine the advantage of a dead-end system … In chemical engineering, biochemical engineering and protein purification, crossflow filtration (also known as tangential flow filtration ) is a type of filtration (a particular unit operation). Crossflow filtration is different from dead-end filtration in which the feed is passed through a membrane or bed, the solids being trapped in the filter and the filtrate being released at the other end. Cross-flow filtration gets its name because the majority of the feed flow travels tangentially across the surfa…
