In-plant control in a superphosphate fertilizer company in Egypt was implemented. The control measures in the plant included utilization of wastewater produced from the scrubbing towers to produce sodium fluorosilicate (Na2SiF6) which is a preservative for Portland cement. Wastewater recovery reduced the pollution amount by 40%. Moreover, it saves almost 600,000 L.E./year. The remained unwanted residue which is a very concentrated highly acidic wastewater was diluted with wasted cooling water in the plant. The proposed study is already implemented and is presently in operation.
