  • 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.

  • Publication number: 20160362321
    Abstract: A treatment system for water having contaminants includes a contaminant-removing tank processing the contaminated water, the tank comprising an interior and a floor defining therebelow at least one depression having a conical shape that upwardly expands from a nadir to the floor, a fluidized bed within the at least one depression and defining a lower bed portion, and a manifold fluidically connected to a contaminated water supply and directing the contaminated water towards the nadir of the depression into the lower bed portion of the fluidized bed to act as a bioreactive filter that removes contaminants out from the contaminated water when the contaminated water flows through the fluidized bed and into the interior of the tank.

  • 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.

  • Publication number: 20140034558
    Abstract: A wastewater treatment system includes independent wastewater treatment facilities. Each of the facilities has wastewater treatment subsystems and is monitored by a central monitoring location. Wastewater collection subsystems hold wastewater to be treated. Monitoring subsystems measure wastewater process parameters. Control devices receive control commands and, dependent upon the command received, alter parameters of the wastewater treatment subsystems. A communication device connects the wastewater treatment subsystems and the control devices and sends information corresponding to the wastewater process parameters measured by the monitors, receives control messages corresponding to the control commands, and transmits control commands the control devices to alter wastewater process parameters.

  • Patent number: 6143187
    Abstract: Improved fluidized bed filters are described and claimed. The filters are exemplified for use in aquarium systems. A preferred embodiment of the filter of the subject invention comprises a cylinder having an inlet port. Water is pumped into the inlet port. The force of the water fluidizes the filter medium within the cylinder. Filtered water escapes the system over the open end of the cylinder or through an outlet channel.

  • Patent number: 5879567
    Abstract: A fluidized bed filter is described and claimed. The filter is exemplified for use in an aquaculture system under hydraulic pressure. A preferred embodiment of the filter of the subject invention comprises a closed cylinder having an inlet port and an outlet port at or near one end. Water is pumped into the inlet port and through a hollow delivery tube positioned within the cylinder and ending a short distance from the closed end of the cylinder. The force of the water contacting the closed end of the cylinder causes the water to change direction drastically creating a flow pattern within the cylinder. This flow pattern exerts a force sufficient to fluidize filter medium within the cylinder. Filtered water escapes the system via the outlet port.
