  • High solubility gas flotation in liquid-solid separation
    Patent number: 4267050
    Abstract: BOD-containing water is purified by oxygenation. The resulting sludge is subjected to flotation with a gas having a solubility in water higher than that of air.The preferred source of high solubility gas is the vent gas from the oxygenation zone or stack gas obtained by burning methane generated by anaerobically digesting the floated solids.Removal of insoluble contaminants from bacterial or bacterial-algal pond effluent using high solubility gas flotation is also disclosed.
