Q2) A municipal wastewater treatment plant has an average flow of 9.92 MLD, and 2 horizontal-velocity grit chambers, one chamber will operate as a standby. The peak flow is 2.51 times the average flow. The channel is to have a depth 1.25 times the width. The horizontal velocity is 0.30 m/s, diameter of sand particle is 0.21mm, density of water 988 kg.m', dynamic viscosity of 1 x 10-3 N.sec/m', and density of particle 2650 kg/m'. a) Design the required grit chambers by determine the following: b) Dimensions of chamber. c) Settling viscosity and Reynolds number. d) Detention time in seconds. c) Length of chamber. f) Total depth assume the free board 0.30m and grit collection depth 0.25m.
