Simultaneous organic matter removal and nitrification in a biofilm-enhanced highly loaded aerated lagoon
Abstract
Aerated lagoon technology is widely used for wastewater treatment in small communities of the United States and Canada. Current design of this type of technology, even if it involves long retention times (hydraulic and solids), is not done purposely to achieve nitrification. However, since aerated lagoons are passive systems importantly influenced by seasonal variations of temperature, nitrification is likely to occur when conditions allow the autotrophic nitrifying bacteria growth rate to be higher than the rate of biomass wastage.
