Some feed streams will pass through the membrane while the rest will be concentrated and circulated through the system. The same principle is now used in industry using ultraļ¬ltration HF perfusion ie. Filtration can be broken down into two different operational modes Normal Flow Filtration and Tangential Flow Filtration.
In protein purification the term tangential flow filtration TFF is used to describe cross-flow filtration with. TFF is most effective when a reservoir is used so that the sample can be recycled through numerous times. This training will also address the topic of integrity testing.
