Aerated lagoon. An aerated lagoon or aerated basin is a holding and/or treatment pond provided with artificial aeration to promote the biological oxidation of wastewaters. There are many other biological processes for treatment of wastewaters, for example activated sludge, trickling filters, rotating biological contactors and biofilters.
Wastewater effluent is the final product of all earlier treatment processes, and it can be discharged to a stream, river, bay, lagoon or wetland. Sometimes effluent is used to irrigate a golf course, green belt or park, or to recharge groundwater (Davis, 2004).
