Design an aerated grit chamber installation for an average wastewater flowrate of
0.3(m^(3))/(s)and a peak flowrate of 1.0
(m^(3))/(s). The average depth is 3 m , the width-to-depth ratio is
1.5:1, and the detention time at peak flow is 3.5 minute. Determine the dimensions of the grit chamber and the air requirement assuming the relevant aeration tank for an aerated grit chamber.
