  • Patent number: 10662637
    Abstract: The subject disclosure is directed to a liquid purification assembly featuring an inclined cell separator located within a chamber. The separator features a plurality of plates oriented perpendicular between opposing spaced-apart substantially vertical weirs. The plurality of plates are substantially parallel to one another and extend longitudinally within the chamber. The first and second weirs can have a plurality of orifices extending therethrough between their front and rear surfaces. The chamber features an influent chamber, an effluent chamber and a sediment collection area along the bottom of the chamber below the cell separator. A net extending from the top edge of the first weir and over a portion of the cell separator is further provided. The assembly features a hinged baffle suspended below the bottom edge of the second weir.

  • Patent number: 9695584
    Abstract: This device serves to improve water quality under gravity flow conditions. The water quality treatment device traps floating debris with replaceable netting, it contains oil spills and settles sediment in self-cleaning settling cells above a collection bunker inside a chamber. The device directs the water below the inclined cells, through the inclined cells, or over the inclined cells, depending on the inflow intensity. All inflowing water enters the net cavity and the net is supported by the inclined cell assembly. The pollutant collection surfaces are overlapping each other and aligned with the water flow direction. A hinged baffle with orifices controls the flow rate through the inclined cells. The netting is replaceable when filled with debris through an access opening in the ceiling of the chamber. The sediment bunker is cleaned through access openings in the ceiling from the chamber inflow side and the exit side.
