Abstract

The report presents design and cost estimating relationships for post aeration after the activated sludge process. Three specific types of post aeration processes are considered: first, mechanical aerators in completely mixed rectangular basins; second, air diffusers mounted in the outlet channel for the plant; and third, air diffusers mounted in rectangular completely mixed concrete basins. The cost of all three types of post aeration is given for 1-, 3-, 10-, 30-, and 100-mgd plants. The cost of the complete plant is given for comparison with the cost of post aeration. (Author)
