  • Patent number: 10053384
    Abstract: A wastewater treatment system includes a wastewater collection system, at least one aeration subsystem aerating the aerobic portion, and at least one filtration subsystem. The wastewater collection system has an anoxic portion, an aerobic portion downstream of the anoxic portion, an anaerobic portion downstream of the aerobic portion. The filtration subsystem includes at least one bioreacting filter receiving fluid from the aerobic portion, being operable to filter wastewater received from the aerobic portion, and discharging filtered fluid into the anoxic portion, an oxygen contactor fluidically connected between the aerobic portion and the at least one bioreacting filter and operable to diffuse oxygen into the fluid being supplied from the aerobic portion, and an oxygen supply operable to supply oxygen to the oxygen contactor.

  • Patent number: 9440870
    Abstract: A wastewater treatment system includes independent wastewater treatment facilities. Each of the facilities has a number of wastewater treatment subsystems. A wastewater collection subsystem holds wastewater to be treated. A pump subsystem moves wastewater from a wastewater collector to a filtration subsystem having a bioreacting filter. The filter has a sump and a fluidized-bed filter therein and supports the filter upright. The filter has an upwardly expanding, hollow, conical filter body with filter media. A monitoring subsystem measures wastewater process parameters. Control devices receive control commands and, dependent upon the command received, alter parameters of the wastewater treatment subsystems.
