Wastewater treatment technologies designed to enhance biological treatment processes for the removal of pollutants
IFAS (Integrated Fixed-Film Activated Sludge)
IFAS combines suspended growth activated sludge with fixed-film media. The fixed-film media provides additional surface area for biofilm formation, enhancing the biological treatment capacity of the system.
IFAS systems offer increased biomass concentration and improved solids retention time, leading to enhanced nutrient removal. They are often used in existing wastewater treatment plants as an upgrade to increase treatment capacity.
