Abstract
A wastewater treatment system includes a first sub-system having a biological treatment unit and a second sub-system having a dissolved air flotation unit. A method of treating wastewater includes directing a first stream of wastewater to a biological treatment unit and directing an overflow stream of wastewater to a dissolved air flotation unit. A method of facilitating treatment of overflow wastewater in a biological treatment system includes connecting an overflow treatment system in a parallel configuration with the biological treatment system, the overflow treatment system having a dissolved air flotation unit, and directing a fraction of activated sludge from the biological treatment system to the overflow treatment system.
