Abstract
Abstract A water treatment system comprises a mixing tank having means for drawing ambient water from a nearby lake, stream, or river for selectively introducing air or chemicals into the water and for thoroughly mixing the water and any air or chemicals so introduced, to thereby treat the water. The treated water is then returned to the ambient water where it is thoroughly mixed therewith by means of a turbine mounted at the end of a conduit.
