Abstract
Process for treating wastewater with activated sludge, comprising mixing incoming wastewater material with activated sludge containing precipitated phosphate particles, to provide a mixed liquid; passing said mixed liquid to an aeration zone in which it is aerated to reduce its content of biological oxygen demand, and to cause the microorganisms present to take up phosphate; separating the phosphate-enriched sludge from the mixed liquid to provide an effluent substantially free of phosphate; passing said phosphate-enriched sludge to a phosphate separation zone, and treating it to cause the microorganisms in the sludge to release phosphate into the liquid phase; add to the sludge a phosphate precipitator, to precipitate the content of water-soluble phosphate; and recirculating said sludge containing precipitated phosphate particles, to mix it with the incoming wastewater material.
