- Process Description
The raw water is pumped from wells to the pressurized sand filters, softeners and activated carbon filters for Turbidity, Hardness and Odour removal respectively. Considering the requirement of the hardness removal, around 22% of the filtered water flow by-passes the softeners and blends with the softened water before activated carbon filter. The product water is distributed to the consumers after disinfection.
The treated water is required to meet "Guidelines for Canadian drinking Water Quality".
