Recovery of wastewater from the low pH clean in place of a UF/MF membrane plant can increase plant operating cost. By adding phosphoric acid and calcium to the wastewater calcium phosphate is formed and precipitated The decanted water can then be sent to the head of the plant, reducing the volume of CIP waste to be treated by 75%. This savings reduces chemical treatment costs as well as increases the productivity of the plant.
