NOVELTY - A wastewater treatment facility comprises primary treatment system including a first tank for containing wastewater received through inlet flow path; rotating media wheels (66) mounted in first tank for rotation within wastewater and each containing a bacterial colony capable of digesting organic carbon in the wastewater and respiring carbon dioxide, and each media wheel including surfaces for supporting algal growth, and an air supply disposed within first tank and having outlets directed at a corresponding one of media wheels to rotate the wheels within the wastewater.    USE - As wastewater treatment facility used in e.g. carbon dioxide generators, biomass production for renewable energy, fertilizer, feed additive, bio-plastics, cosmetics, pharmaceuticals, fabrics, bio-fuels.    ADVANTAGE - The wastewater treatment systems avoids the problems associated with prior algal biofuel production efforts. The rotating media wheels essentially increase the available surface area for algal growth. The algal biomass is easily extracted from the clarifier tanks of this system than from the raceway pond of the prior system. The biological processes occurring in the media wheel systems are self-initiating and self-sustaining. Thus, the facilities overcome the problems associated with renewable energy from biomass. The system provides an extremely environmentally-conscious solution to the ongoing problem of treating wastewater, with the beneficial adjuncts of abating greenhouse gases from wastewater treatment, capturing carbon dioxide from carbon dioxide emitters, and producing a renewable resource for use in other processes.    DETAILED DESCRIPTION - A wastewater treatment facility comprises an inlet flow path for receiving wastewater from a source; a primary treatment system including; a first tank for containing wastewater received through the inlet flow path; rotating media wheels (66) mounted in the first tank for rotation within the wastewater and each containing a bacterial colony capable of digesting organic carbon in the wastewater and respiring carbon dioxide, and each media wheel including surfaces for supporting algal growth, the surfaces arranged to be alternately immersed in the wastewater and exposed to sunlight; an air supply disposed within the first tank and having outlets directed at a corresponding one of the media wheels to rotate the wheels within the wastewater and operable to aerate the wastewater; and a primary outlet for discharge of effluent treated by the primary treatment system after contact with the bacteria and algae; a secondary treatment system including; a second tank for receiving the effluent discharged from the primary outlet of the primary treatment system; media wheels, each configured substantially identical to the media wheels in the primary treatment system; an air supply disposed within the second tank and configured substantially identical to the air supply of the primary treatment system; and a secondary outlet for discharge of effluent treated by the secondary treatment system after contact with the bacteria and algae.
