Question

Wastewater flow from a small community averages 3400m3/d during the winter and 6600m3/d during the summer.
The average temperature of the coldest month is 100C, and the average temperature of the warmest month is 300C.
The average BOD5 is 200mg/L with70% being soluble. The reaction coefficient k is 0.23d-1 at 200C, and the value
of temperature coefficient is 1.06. Prepare a preliminary design for a facultative pond treatment system for the
community to remove 90% of the soluble BOD.

1. Find the volume of facultative lagoon to remove 90% of the soluble of BOD

Answer 1
