| Summary: | A review of published literature and field evaluations revealed the presence of over 3500 waste treatment lagoons currently in operation in the United States. The three types of lagoons in use include: Oxidation lagoons; Aerated lagoons; and Anaerobic lagoons. Oxidation lagoons depend upon algae to supply oxygen by photosynthesis and degrade the waste products. Effluent quality is determined by the quantity of algae in the effluent and several methods of algae removal are currently under investigation. Aerated lagoons may be merely oxidation ponds with supplemental aeration, partially mixed activated sludge (facultative aerated) or complete mix activated sludge (CMAS) systems. Anaerobic lagoons can provide up to 80% BOD removals, but must be followed by some type of aerobic treatment to produce a high quality effluent. The review has demonstrated that lagoons do have applicability to the total waste treatment problem. |
