downstream of the flotation process. The water is pumped into a pressure vessel, at a pressure of 4 to 8 bar. Air is supplied to the pressure vessel via an air compressor. Because of the high pressure, more air can be dissolved than is possible under atmos-pheric circumstances. The supersaturated water flow is transported from

MODULE 9.

Waste-activated sludge can be thickened effectively by flotation or centrifugation; however, chemical additions may be needed to ensure high solids capture in the concentrating process. Anaerobically digested sludge is a thick slurry of dark - coloured particles and entrained gases, principally carbon dioxide and methane.

Dissolved Air Flotation System DAF Hoffland Environmental .

A portion of the treated water is utilized to provide the media to deliver the dissolved air to the DAF by pumping into a pressure tank with compressed air at 75 psig. Drawing air into a pump suction is not recommended by HEI because the inherent pump cavitation dramatically shortens the life of the high pressure centrifugal pump.

Optimizing dissolved air flotation design system

Dissolved air flotation takes advantage of the effect of pressure on the solubility of gases in liquids. At high pressure more gas is soluble in the liquid than at lower pressures, meaning that the extra gas dissolved at high pressure must come out of solution when pressure is reduced.

It can be assumed that about 40 to 60 liters of flotation sludge per m³ of wastewater are produced at average concentrations. This is approximately 4 to 6 % of the volume of the waste water entering the DAF system. The flotation sludge further dehydrates during storage, thus the longer it is stored, the less water content the sludge has.
