Abstract: Methods for regenerating filter aids which comprise inorganic, natural or semisynthetic filter aids. The method comprises subjecting the filter aid to a first treatment with an aqueous alkaline solution, treating the filter aid with enzymes, treating the filter aid with a surfactant, and subjecting the filter aid a second treatment with the aqueous alkaline solution. The enzyme treatment and the surfactant treatment steps may be carried out simultaneously or in any order.
