Controlling phosphorous discharged from municipal and industrial wastewater treatment plants is a key factor in preventing eutrophication of surface waters. Phosphorous is one of the major nutrients contributing in the increased eutrophication of lakes and natural waters. Its presence causes many water quality problems including increased purification costs, decreased recreational and conservation value of an impoundments, loss of livestock and the possible lethal effect of algal toxins on drinking water. Phosphate removal is currently achieved largely by phosphorus precipitation to remove the inorganic forms of phosphate by the addition of a coagulant and a mixing of wastewater and coagulant.
