  • Hydraulic air compressor and biological reactor system and method
    Patent number: 6272839
    Abstract: A hydraulic air compressor (HAC) and system and method are set forth for aerobic treatment of waste effluent and for generation of power. The waste liquid is supplied to an upper end of a down shaft for the HAC which includes injection of air into the liquid for compression and for aerobic treatment of the liquid. The liquid falls to a separator where compressed air is liberated from the liquid. The liquid is returned to, for example, a sludge pond for recirculation and treatment.
