  • Patent number: 6488854
    Abstract: A improved activated sludge system and method for treating wastewater containing contaminants is disclosed which offers a broad array of advantages over conventional activated sludge wastewater treatment systems, including smaller size, higher rates of operation, higher oxygen transfer efficiency, lower operating costs, and a substantially decreased level of excess sludge production. The improved activated sludge waste treatment system of the present invention has two processing tanks rather than the several tanks that are commonly found in activated sludge systems for treatment and sludge management equalizations, including anaerobic processes. The first processing tank is a contact tank which hosts a reaction which functions not merely to digest the maximum amount of contaminants, but instead to bind contaminants to the microorganisms through absorption, adsorption, precipitation, or digestion so that they can then be removed from the liquid in a solid/liquid separator.
