Direct the retentate and permeate to a waste container. 3. Start the feed pump and achieve the following conditions by partially closing the retentate valve and adjusting the pump speed: – Feed flow of 5 L/min/m2 – Retentate pressure of 2–15 psi (0.14–1.03 bar) to achieve approximately 30% conversion 4.
WebThe equation of calculation of normalization can be derived by using the following simple four steps: Firstly, identify the minimum and maximum values in the data set, denoted by x (minimum) and x (maximum). Next, calculate the range of the data set by deducting the minimum value from the maximum value. Next, determine how much more in value ... WebTransmembrane Pressure (TMP) Calculation. Give the pressures you can read on your pressure gauge in any unit to get the TMP. * If you do not measure the pressure put 0 (Zero) in the box. The calculation of TMP uses the formula: (Inlet pressure + Outlet pressure)/2 - Permeate pressure.
