Ozonation to the Rescue At our unit Formulations Hyderabad Plant 2, the process effluent generated during the cleaning of machines that manufacture Dipyrodamol (DIPY) had high Chemical Oxygen Demand (COD), and Biochemical Oxygen Demand (BOD). Not only did the effluent contain chemical content beyond the statutory limits, it was also eroding the RO membranes. It was imperative to find a permanent solution to this issue. In January 2015, we installed an Ozonation System at the Wastewater Treatment Plant to treat this high-pollution load influent.   Given below are the levels of pollutants before and after treatment. Particular   Raw Effluent Before   Treated Effluent After Ozonation pH   4 - 7   6 - 7 TDS   160 - 180   ~ 150 TSS   100 - 2000   ~ 200 Turbidity   500 - 1600   < 10 BOD   7000 - 25000   < 250 COD   10000 - 50000   < 2000 Color   Dark Yellowish Green   Colourless   Post ozonation, the effluent is treated at the Wastewater Treatment Plant and the resultant discharge easily meets the statutory levels.
