Ferrous sulfate is used as a coagulant and lime as a coagulant aid at a water treatment planttreating 26,500 m3/day. The specific gravity of the floc and adhered suspended material is 1.005 at a temperature of 10oC. Determine:a. The overflow rate in m3/d-m2if the flow is and the clarifier is 18.29m by 36.57m. b.The settling rate in cm/sec for the overflow rate determined in 1(a) above. c.The diameter in cm of the of the smallest floc particle that is of a size that is 100% removed if it is assumed that the particles are spherical in shape.
