A rapid sand filter is to be provided in a water treatment plant, to process 60 MLD of water for a town. There is a provision of allowing 3% of the filtered water for storage to meet the backwashing requirement. Rate of filtration for the filter system is 20 m3/m2/hr. Each day 20 min of backwashing is done. Then, A Flow of water during filtration is laminar flow and flow of water in case of backwashing is turbulent. B The area of filter unit is 128.75 m2 C The area of filter unit is 130.55 m2 Correct Option Rapid sand filter is less efficient in removing bacteria. Correct Option
