Microfiltration Process for Continuous Removal of Solid Particles from Cold-Rolling Emulsions



Microfiltration is used for treatment of rejected oil-in-water emulsions: mostly as end-of-pipe treatment for separation of oil and water. However, microfiltration for continuous cleaning of emulsions with removal of solid particles, but without removal of emulsified oil, is not an established process. The described research project aims for development of a continuous cleaning process based on microfiltration for removal of solid particles from cold-rolling emulsions without removal of emulsified oil. The new cleaning process for emulsions can be advantageous compared with existing processes for removal of solid particles smaller than 10 μm.
