primary water treatment dissolved air flotation unit
Primary Treatment of wastewater with air flotation ...
Dissolved Air Flotation is the preferred option for primary treatment where the contaminants are fine suspensions, colloids, oil and grease and flocculable colour. Depending on the fraction of suspensions and oil grease that exert BOD, reducion efficiency of BOD in the range of 25% to 90% is achievable.

Flotation in Water Treatment | SpringerLink
Abstract. Dissolved-air flotation is a very effective solid-liquid separation process used in water treatment, as an alternative to sedimentation, to lower the solids concentrations before granular filtration. This enables filters to be operated more effectively and cost efficiently to produce a filtered water quality suitable, after ...
