Dissolved Air Flotation for Water Clarification

An alternative technique for the clarification of algalrich waters is dissolved air flotation DAF 5 The principle of sedimentation is based on removal of settleable floc particles by the process of gravity settling while the principle of DAF is based on the removal of bubbleflocs agglomerates as air Reduce your Sewer Use ByLaw Fees with an H2Flow DAF and get into compliance Dissolved Air Flotation DAF is a technology used extensively for wastewater treatment in food plants oil gas mining pulp paper many major industries and municipal wastewater plants It also has a very good fit for its use in clarification of drinking water treatment especially for difficult to flocculate Dissolved Air Flotation DAF is another form of clarification process that relies on flotation of floc particles to the surface instead of gravity sedimentationIt is suited to particular quality raw water streams generally low turbidity coloured waters which would
