ABSTRACT:
Use and reduction of wastewater or “pond water” created by the wet-process phosphoric acid manufacturing there is created a large amount of wastewater or “pond water” to substantially reduce or eliminate the discharge of pond water with contaminants to the environment. By partially treating pond water with known industry standard processes and using the treated pond water for use as required makeup or cooling water in an electric power generator or any other Industry requiring makeup, cooling or process water will substantially reduce or eliminate the need for the phosphoric acid manufacturers to discharge the contaminated water to the environment and reduce the quantity of fresh water that would normally be required by these other industries using the treated pond water for cooling or makeup water.
