Membrane performance restoration. I. Abattoir process streams, cleaning regimes for UF membranes
Ultrafiltration offers attractive advantages in the treatment of effluent streams originating from an abattoir. However, severe fouling caused by the presence of proteinaceous and fatty constituents in such streams reduce membrane transport rates to unacceptable levels in a very short period. Cleaning regimes by which membrane transport rates can be restored and maintained effectively have been evaluated both in the laboratory and applied in the field with success.
