Question 4 Estimate the particle removal efficiency in a rectangular sedimentation basin with a depth of 4m, width of 8m, length of 40m, and a process flow of 800m3/h. Assume the following influent particle characteristics. Estimate the removal efficiency under peak flow given a peak-factor of 1.5 . Plot the influent and effluent concentrations (average and peak flow) against settling velocity using a histogram
