Trans-Membrane Pressure (TMP) Calculation for UF (Manual)
May 28, 2021
Example calculation of TMP
To calculate accurate Trans-Membrane Pressure (TMP), it is necessary to involve the height difference of inlet and outlet pressure gauges.
TMP = (Pin - Hin) - (Pout + Hout)
= (70 - 10) - (20 + 25)
= 60 - 45
= 15 kPa
Note, the following formula may also be used:
TMP = Pin - Pout - total delta H
= 70 - 20 - (10 + 25) = 15 kPa
