Question 60
CENAT2 marksNeeds review
A sewage treatment plant receives sewage at a flow rate of 500 m
/day. The total suspended solids (TSS) concentration in the sewage at the inlet of primary clarifier is 200 mg/L. After the primary treatment, the TSS concentration in sewage is reduced by 60 %. The sludge from the primary clarifier contains 2 % solids concentration. Subsequently, the sludge is subjected to gravity thickening process to achieve a solids concentration of 6 %. Assume that the density of sludge, before and after thickening, is 1000 kg/m
.The daily volume of the thickened sludge (in m
/day) will be __________. (round off to the nearest integer)Log in to check the answer
