An apparatus for recycling wastewater solutions includes a treatment tank and an air-operated pump and piping system for pumping wastewater contaminated with oil, heavy metals, and suspended solids from industrial equipment such as a jetwasher to the treatment tank, and for subsequently returning the purified water solution to the industrial equipment for reuse. A weir tube initially skims oil contaminants from the surface of wastewater in the treatment tank into a collection vessel. The recycling apparatus is powered solely by compressed air, which drives a rotary air motor powering mixing vanes in the treatment tank. Exhaust air from the mixing motor outlets into the treatment tank for the purpose of creating turbulence to enhance mixing. Air directed through an induction nozzle entrains flocculating polymer powder from a hopper in an air stream within a polymer supply hose exhausting into the treatment tank. After contaminant flocculation and settling, a decant outlet and a sludge outlet on the treatment tank decant purified water solution, and drain a contaminant sludge, respectively, into a strainer basket disposed at the top of a recovery barrel.
