Cross-flow microfiltration.

Cross-flow microfiltration of beer, skim milk, and fruit juice is studied is pilot plant scale utilizing a new filtration principle developed jointly with Department of Chemical Engineering (Gunnar Jonsson). Computer controlled, brief back-flush pulses abate fouling and allow for a high flux and a 100% transmission af proteines, while energy consumption is reduced considerably. The technique will eventually replace conventional kiselguhr filtration, which presents hazards to both the working force and the environment.
