IFAS blends the process flexibility and advanced treatment benefits of activated sludge with the inherent stability and ease of operation of attached growth film systems, increasing capacity and/or level of treatment. Adding attached growth media to a suspended growth reactor provides additional stabilized biomass for increased treatment without increasing the clarifier solids loading. Media can be added to either aerobic or anoxic zones for kinetic optimization, resulting in less tankage.
• attached growth and suspended biomass
• maximizes biomass concentration
• excellent settling characteristics minimizes tankages
