Abstract:
A method for reducing phosphorous in a body of water, comprising the acts of:calcining a plurality of rocks containing calcium carbonate to convert said calcium carbonate to calcium oxide, and collecting carbon dioxide formed as a result of said calcining process; crushing said plurality of calcined rocks; pumping source water from said body of water into to a plurality of retaining cells; flocculating said phosphorus by introducing said plurality of calcined rocks into said source water in said retaining cells; settling out a phosphorous precipitate formed by said flocculating act; adjusting the pH level of said flocculated source water to a predetermined range of values by pumping said carbon dioxide created by said calcining of said rocks into said source water to create treated water; and transferring said treated water back to said body of water.
