  • Patent number: 11951423
    Abstract: A screening system for solid removal includes a housing and a screen positioned within the housing. A flow inlet is operatively connected to an interior chamber defined by the screen. A sump is downstream from the flow inlet for capturing solids that do not pass through the screen. A flow outlet is downstream from the screen in fluid communication with the flow inlet. A moveable cleaning assembly may be positioned either within a perimeter of the screen, around the perimeter of the screen or both. The moveable cleaning assembly is moveable with respect to the screen.
    Type: Grant

  • Patent number: 10745310
    Abstract: A dewatering system for removing solids from an influent includes a filtration assembly and a feed pipe upstream thereof. The dewatering system includes a solids receptacle downstream of the filtration assembly, and an effluent collector adjacent to the filtration assembly and in fluid communication with the filtration assembly. The dewatering system includes a sensor to sense a characteristic of an influent, an effluent and/or a solid. A control system is operatively connected to the sensor to receive a sensor signal therefrom and to generate an adjustment signal based on the sensor signal to improve the efficiency of the dewatering system.

  • Publication number: 20200129894
    Abstract: An effluent collector includes a filtrate receiving portion having a filtrate opening, and a pressate receiving portion having a pressate opening. The effluent collector includes a diverter barrier adjustably positioned above the pressate receiving portion. The diverter barrier is configured to adjustably direct at least a portion of a flow path toward or away from the pressate receiving portion.
