  • Publication number: 20240189083
    Abstract: An air handling and filtration/treatment system (whether portable of affixed) for the mitigation and management of airborne biological contaminants (either those pre-existing or those that may become generated) that includes a suspended air in-take assembly containing a removable filter; that includes a deflector having ducting leading to a housing assembly that includes a UV sanitizer, a fan assembly and controller; and includes an outflow assembly that includes ducting leading to a position able manifold having a plurality orifices. The manifold and deflector are laterally offset from the housing assembly and vertically aligned with each other. The manifold is positioned to encircle the bioaerosol source.

  • 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.

  • Publication number: 20140037058
    Abstract: An x-ray system comprises a c-arm base unit, a detector tray and a c-arm movably supported on the base to permit articulation above a patient to be examined. The c-arm has an x-ray emitter emitting x-radiation in an x-ray field, an x-ray detector detecting the x-rays and removably resting at the detector tray. An upper portion of the c-arm holds the x-ray emitter. The c-arm has a retractable lower portion with an articulating assembly removably holding the detector tray at the lower end and articulating the detector tray away from or in towards a center of the c-arm to stowed positions when attached. The c-arm slides with respect to the upper portion of the c-arm such that, when retracted, the upper portion can be placed over the patent who is resting on a surface having an obstruction therebeneath that would prevent the lower portion from accessing under the surface.
