BENTONITE is modified with quaternary amines, rendering it organophillic. This modified bentonite can be used in powder or granulated form (granulated in cartridge filter applications) to remove mechanically emulsified oil, grease and other sparingly soluble large chlorinated hydrocarbons from water and waste water. When used in the granulated form, the Organoclay granules are mixed with anthracite to prevent early plugging of the filter by oil and grease.
