Abstract:
A waste processing system for removing contaminants from a wastewater stream, comprising:a first container having wastewater from said wastewater stream admitted thereinto, activated sludge being introduced into said first container to react with said wastewater contained therein to cause said contaminants to bind to microorganisms contained in said activated sludge; a solid/liquid separator for receiving said wastewater containing said contaminants bound to said microorganisms from said first container, said solid/liquid separator having as a first output wastewater from which said contaminants bound to said microorganisms have been removed, said solid/liquid separator also having as a second output an activated sludge including said contaminants bound to said microorganisms; and a second container for receiving said activated sludge including said contaminants bound to said microorganisms from said solid/liquid separator, said second container containing a sufficiently high concentration of activated sludge to ensure substantially complete digestion of said contaminants, said activated sludge in said second container comprising the source of said activated sludge which is introduced into said first container.
