(a) How does temperature affect biological processes?

(b) The rate of BOD reduction in aeration of a synthetic wastewater decreased 25% when the temperature of the laboratory fermentation lank was lowered from 20° to 15°C. Using Eq. (12.35), calculate the temperature coefficient. How many degrees of temperature drop are required to reduce the rate of BOD reduction by one-half?
