Abstract |
Researchers have concentrated a great deal of effort toward developing a workable, odorless method of liquid waste disposal. One of the simplest methods of odorless waste treatment is the aerobic biological treatment process. The two major forms of aerobic treatment for municipal wastes are the activated sludge process and the trickling filter. Extended aeration, a modification of the activated sludge process, has primarily been used to treat livestock wastes aerobically. Two extended aeration processes, the oxidation ditch and the aerated lagoon, are discussed in this report. |
