(B) Increasing cell concentration increases … WebDevelop transmembrane pressure (TMP) versus flux data at a given cross flow: 1. Increase the feed pump speed to the desired cross flow rate while simultaneously and slowly increasing the permeate pump speed to the desired flux level. 2. Record inlet, outlet, and permeate pressures over a 20–30 minute period. 3. Monitor stability of TMP. WebFlux, [3] transmembrane pressure (TMP), Permeability, and Resistance are the best indicators of membrane fouling. Under constant flux operation, TMP increases to compensate for the fouling. On the other hand, under constant pressure operation, flux declines due to membrane fouling. budweiser what\\u0027s up commercials
