The following batch settling column data are available. The data given are percent removals at the sample times and depths shown. a. Plot the graph of depth versus sampling time and draw the isoconcentration, lines at 10% intervals. b. Calculate the removal at 40 minutes. c. Assume retention time as 40 minutes and calculate the overflow rate. d. Calculate the design overflow rate and detention time based on the design guidelines discussed in the lecture.
