Specifying the Filtration TMP Increase between Processes for UF

WAVE makes possible the specification of increases of pressure drop across the UF membrane (trans membrane pressure or TMP) between successive Backwash, Acid/Alkali CEB and CIP steps per hour.

It will help to estimate the energy needed for ultrafiltration by taking into account solid accumulation/fouling of the UF membrane during use. By using the appropriate rates of TMP increase and Backwash/CEB/CIP frequencies, one can incorporate the effect of deteriorating membrane performance between cleanings.

The TMP increase between processes can be accessed as shown.

Notes:

WAVE sets the values for transmembrane pressure drop (TMP) increase with time to zero by default. The user is urged to use an appropriate value based on data and experience.
The UF System Diagram is displayed automatically in the Filtration Window and is updated based on the changes made in other Windows.
