Variable-flow software lowers costs by automatically regulating flow into the dissolved air flotation tank through dual saturators Photos: CDM

High-rate dissolved air flotation reduces the 200-mgd operation's backwash volume from 8 to 1.4 mgd. Backwash is treated and recycled to the plant's intake as raw water, eliminating discharge to the reservoir and saving potable water and energy. Graphic: CDM
