NOVELTY - The energy conserving wastewater treatment system comprises a synthesis gas generator that produces synthesis gas from a refuse derived fuel, an organic waste digester that produces biogas, a combined synthesis gas and biogas storage reservoir in communication with both the synthesis gas generator and the organic waste digester, and a boiler in communication with the combined synthesis gas and biogas storage reservoir. The treatment system is fueled by alternate fuel sources. The organic waste digester produces biogas from anaerobic digestion of biosolids.    USE - The wastewater treatment system is useful for conserving energy in a plant (claimed).    ADVANTAGE - The wastewater treatment system removes contaminants from water in an economical and an environmentally friendly manner.    DETAILED DESCRIPTION - The energy conserving wastewater treatment system comprises a synthesis gas generator that produces synthesis gas from a refuse derived fuel, an organic waste digester that produces biogas, a combined synthesis gas and biogas storage reservoir in communication with both the synthesis gas generator and the organic waste digester, and a boiler in communication with the combined synthesis gas and biogas storage reservoir. The treatment system is fueled by alternate fuel sources. The organic waste digester produces biogas from anaerobic digestion of biosolids. The boiler is present in communication with an electricity generating apparatus that is provided as a turbine. The turbine is present in communication with a heat exchanger that transfers steam from the turbine to the organic waste digester. The system further comprises a synthesis gas cleaning equipment that cools the synthesis gas and removes contaminants from the synthesis gas, a heat exchanger that transfers heat from the synthesis gas to another location in the system, a phosphorus enhancing subsystem, a heat transfer apparatus that transfers heat from the synthesis gas and sends the heat to a sludge dryer, and a biogas cleaning equipment that cleans the biogas. The other location is the boiler and a biosolids dryer. The synthesis gas cleaning equipment is located upstream from the combined synthesis gas and biogas storage reservoir. The boiler is present in communication with the organic waste digester and with a building to transfer steam thereto for comfort heating or cooling. The subsystem comprises a centrifuge that is present in communication with of a thickening tank, the organic waste digester and/or the biosolids dryer. The boiler receives the synthesis gas and/or the biogas. The heat transfer apparatus is a heat recovery steam generator. The electricity generating apparatus comprises a heat exchanger that transfers water from the electricity generating apparatus to the organic waste digester, the dryer, the boiler, the centrifuge, and/or the building. An INDEPENDENT CLAIM is included for a method for conserving energy in a wastewater treatment plant.
