  • Patent number: 11371234
    Abstract: A grit removal unit including a cylindrical grit removal chamber above a grit storage chamber, with an opening to the grit storage chamber through the grit removal chamber bottom. At least one layer plate is an inverted truncated cone around the center axis which is spaced from the grit removal chamber vertical wall to allow fluid flow therebetween. Concentric inverted truncated cone lamella plates are supported in the grit removal chamber above the layered plates, with the lamella plates radially spaced from one another relative to the center axis. An influent opening in the grit removal chamber vertical wall below the layered plates allows fluid and grit into the grit removal chamber, and an effluent opening in the grit removal chamber vertical wall above the lamella plates allows fluid to exit the grit removal chamber.

  • Patent number: 11371233
    Abstract: A pop-up emitter includes a conduit, a cover plate, a pop-up lid, and a clip. The conduit defines a flow channel configured to establish fluid communication with a drainage system. The cover plate protrudes radially outward from a top end of the conduit and about the flow channel. The cover plate defines a slot along a top surface of the cover plate. The pop-up lid has a horizontally extending pin protruding outward therefrom. The pin is disposed within the slot. The pop-up lid is configured to pivot about the pin to transition between a first position where the plate covers the flow channel along the top end and a second position where the flow channel is exposed such that water is emitted therefrom.

  • Patent number: 11371203
    Abstract: A storm water runoff and erosion control device includes a rigid frame covered by a layer of mesh material. The frame defines an interior space that is filled with filtration material. The device may be configured as a wattle having an elongated frame with a triangular cross-section. The wattle may be extended along the contour of a hill to reduce erosion, or it may be placed at the entrance to a drainage inlet to slow the velocity of, and filter sediment and contaminants from, water entering the inlet. Alternatively, the device may be a compact filter that is a cube, cylinder, sphere, or other suitable geometry. A plurality of these compact filters may be placed in the basin of a storm water drain, and piled sufficiently high to cover the outlet from the basin. Thus, all the water in the basin must pass through the compact filters before exiting.

  • Patent number: 11363763
    Abstract: A plant growing system has a number of modular units arranged together on a flat surface in side of a growing room. The modular units have rigid boxes therein with vertical holes therethrough inside of which is located a growing soil. Water and nutrients are pumped from a reservoir to a distributor located in a growing soil of the rigid boxes as called for by moisture sensors, which activates a controller to turn ON a delivery pump. When moisture and nutrients need to be removed from an impermeable flexible liner located below the modular units, the controller turns ON a return pump, which pumps the excess water and nutrients back to the reservoir.

  • Patent number: 11331601
    Abstract: In a wastewater treatment system, a clarifier has a submerged effluent launder, with a sloped, submerged plate that allows clarified liquid to exit through submerged openings. The sloped surface tends to accumulate solids, which can lead to algae growth. Typical internal scum collection system equipment prevents any efficient way to clear the accumulated sludge off the launder surface because of interferences. As disclosed here, a scum discharge area or box is placed external to the clarifier in one embodiment. Scum is wiped from a vertical surface of the launder assembly, above the sloped launder surface, and swept over a scum beach at one position in the clarifier, to drop into a lower trough and the flow out through the clarifier wall to a drop out box or scum discharge area. This allows for a rake-attached, sweeping launder wiper to be moved with the clarifier's rake to remove the accumulation of sludge from the launder's submerged surface, without elaborate moving parts.

  • Patent number: 11293171
    Abstract: A two-stage filtering drain cover that can be retrofitted to an existing, original construction, areaway drain cover. The filtering drain cover of the invention inhibits the accumulation of debris on the existing drain cover, and passage of debris into the drain, and helps to prevent clogs and flooding. The outer cover member of the device is configured with passages that permit liquid flow through the outer cover while filtering larger size debris particles that may be entrained in the passing liquid. A perimeter wall on the outer cover and with similar liquid flow passages stops larger debris from passing the outer cover. An inner filter member fits within the outer cover and is configured with relatively smaller passages to obstruct smaller sized debris that may have penetrated the outer cover from passing into the drain.
