WebJun 10, 2016 · Dead-end filtration means that a one-fold concentrated sample recovered is not recirculated as in crossflow filtration. Besides small samples, larger volumes from 100 ml to 5 l are also commonly used in laboratories and need to be concentrated or their buffers exchanged, such as cell culture supernatants prior to purification. WebFeb 19, 2024 · Usually four blocking models are used for description of filter fouling: complete blocking, standard blocking, intermediate blocking, and cake filtration. The general blocking law for all four cases is: (2) The blocking index n varies with values between 0 and 2 in dependence on the fouling mechanism. galaxy j3 6 battery life
