WebFeb 22, 2024 · Tangential Flow Filtration (TFF) TFF is also called cross-flow filtration, and in this case, the flow of the biologic feed stream is tangential across the filter membrane at a positive pressure. While the flow passes over the membrane, the feed stream portion that is smaller compared to the pore size of the membrane passes … WebAug 31, 2024 · Crossflow filtration is viable for the following types of ultrafiltration membranes: Spiral wound UF membranes. Hollow fiber UF filters. Tubular UF membranes. Direct flow UF filtration. This is also commonly referred to as dead-end UF filtration whereby pressure is exerted to force the feed water through the UF membrane pores.

WebAug 1, 2024 · Many simple filtration processes use a dead-end technique with the flow of liquid to be filtered directed perpendicular to the filter surface. This is effective when the concentration of particles to be removed is low or the packing tendency of the filtered material does not produce a large pressure drop across the filter medium. WebIn dead-end filtration the flow of the feed solution is perpendicular to the membrane surface. On the other hand, in cross flow systems the flow passes parallel to the membrane surface. [23] Dead-end configurations … Cross-flow and dead-end membrane filtration differ in several key ways, including: 1. Filtering method —In dead-end filtration, the feed flow comes to a dead end after filtration. Cross-flow filtration means the feed flow moves across the filter, and the concentrate port allows a controlled bleed of feed flow. 2. … See more Dead-end filtration offers certain benefits for simple, small-scale operations, but cross-flow filtration is better for a wider variety of industrial applications.
