Vermiculite Filtration for Removal of Oil from Water

Abstract

In the present study expanded vermiculite in the granular form was used in filtration studies (column studies) in treating four representative oil-in-water emulsions. The four oil-in-water emulsions were standard mineral oil (SMO), canola oil (CO), Kutwell oil (KUT45), and refinery effluent (RE) from the Co-operative Oil Refinery, Regina, Canada. The concentrations of oil in these emulsions varied from
