The process provides improved recovery of phosphoric acid (water soluble P2O5) which directly results in improved Plant P2O5 efficiencies and lower P2O5 concentration in the cooling pond water. Phosphoric Acid is normally the highest concentration of the acidic components of the cooling pond water which must be neutralized prior to closure.
