Engineering Reviewand Problem Solving Expansion of aeration basins difficult due tohigh groundwater level at site. Evaluated expansion of trickling filters Discussed options with Brentwood Industries Concrete tanks with aluminum domes 4th trickling filter would be expensive Investigated potential for upgrading aerationbasins with IFAS media
IFAS Systems Submerged media carriers added toactivated sludge aeration basins Significantly increases biomass inventory Little to no increase in solids loadingto final clarifiers Increases sludge age – good fornitrifying bacteria Come in different varieties
