At the end of the gradient of filtration (time re), the total flow rate of the permeate (QP,c) is set to a constant value by increasing the transmembrane pres- sure (TMP) through the V1 valve. To prevent membrane fouling (which requires lengthy and costly cleaning procedures) the TMP is limited to a maximum value: TMPa.
In order to better understand the effect of transient filtration parameters on the filtration performance during cross flow microfiltration of yeast suspensions, a laser distance sensor was used to measure on-line the height of the filter cake in a specially designed flat channel module.
a total of 420 cm2 filtration area, were used with a recirculation flow rate of 624 ml/min. Measurement of transduction efficiency of retroviral process samples Anion-exchange chromatography Transduction efficiency assays (ONPG assay) were Batch chromatography performed as described elsewhere .

12/24/2015 · Tangential flow filtration (TFF) involves passing a liquid tangentially across a filter membrane. The sample side is typically held at a positive pressure relative to the filtrate side. As the liquid flows over the filter, components therein can pass through the membrane into the filtrate.
