Aeration transfers the quantity of oxygen necessary to support biological growth, and also provides mixing to disperse the dissolved oxygen and suspend solids. Surface aeration is still the simplest and most efficient way to go. Submerged aeration technology, however, has undergone vast improvements to accommodate limited space or high strength waste in existing systems. In either case, equipment reliability during this stage is critical. | |
