ABSTRACT:
A treatment composition and method is provided for removing a plurality of contaminants from a wastewater system in the form of a nonleachable sludge. The treatment composition comprises an alkali or alkaline carbonate; activated montmorrilonite; a catalyst, such as zirconium and polyelectrolyte; one or more flocculants, such as a metal salt and calcium oxide, lime, or calcium hydroxide; and bentonite. Additionally, the treatment composition may contain soda ash, lignite, and activated carbon. The treatment composition is introduced and mixed with the wastewater, which is then filtered to produce a sludge containing the contaminants in a nonleachable form.
