Q4) Determination of flow rate - equalization volume requirements and effects on BODS mass loading For the flow rate and BOD concentration data given in the table determine; (1) The in-line storage volume required to equalize the flow rate (2) Time period when the equalization tank is empty (3) The effect of the flow equalization on BOD mass - loading rate. Given data average flow m'/s (2) 0.375 0.320 0.265 0.230 0.205 average BOD5 mg1 (3) 160 125 Time (1) M-1 1-2 2-3 3-4 4-5 5-6 6-7 7-8 S-9 9-10 10-11 11-N 60 55 0.200 70 0.220 100 0.305 0.455 0.510 0.525 0.530 0.525 0.505 0.485 140 n-1 1-2 2-3 3-4 4-5 5-6 6-7 7-8 0.450 0.425 0.425 0.430 0.465 0.500 0.500 0.480 185 210 225 230 230 220 210 200 190 180 185 220 290 315 255 S-9 9-10 10-11 11-M 0.445 190 Q4) Determination of flow rate - equalization volume requirements and effects on BODS mass loading For the flow rate and BOD concentration data given in the table determine; (1) The in-line storage volume required to equalize the flow rate (2) Time period when the equalization tank is empty (3) The effect of the flow equalization on BOD mass - loading rate.
