  • Patent number: 10183240
    Abstract: Systems, devices, and methods for providing nutrient removals in an up flow filtration storm water system for treating water to very high clean levels using filtration media. A filtration media supported by a screen above an angled floor in a vault allows for incoming storm water to pass into a void space above the angled floor into the screen and filtration media and then out an outlet to the vault. The filtration media can include recyclable and/or natural particles. Layers of river rocks can be placed on top of and below the filtration media. Water sprayers can further liquefy sediment and debris that fills the void space between the angled floor and the bottom of the screen. The captured debris can slide down the angled floor, where a vacuum hose from an above ground vacuum truck can remove the debris and sediment. The long lasting filtration media can be cleaned by being backwashed.

  • Patent number: 10155670
    Abstract: Vaults, boxes, systems, and treatment methods to capture pollutants from stormwater runoff and prevent conveyance of the pollutants from entering a receiving water body or landscape area, which can be part of a permanent stormwater drainage infrastructure. A polymer system with at least one polymer log can be used to treat stormwater runoff and any stormwater conveyance, such as a pipe, box culvert, ditchline, and the like. Once stormwater has been dosed with polymers, the treatment easily retains the pollutants, and the one or more polymer logs continue to enhance water quality, while providing an easy method for servicing polymer logs without requiring service technicians to enter the vault. A hydroslide servicing system can include pivotal spray heads to pivot to parallel positions over a sloped floor to flush debris toward easy to reach locations to be vacuumed, and vertical spray heads which can break up debris bridges.

  • Patent number: 10130901
    Abstract: An example system includes an auger assembly that is attachable to a vacuum system, in which the auger assembly includes a hose, an auger, and an auger motor. The hose includes an inlet at a distal end and an outlet at a proximal end. The auger includes a shaftless helical blade having a portion that is radially enveloped by the hose. The vacuum system is adapted to suck material from the septic tank or pit latrine via the hose. The auger motor is adapted to rotate the auger about a helical axis in a first direction, in which the rotation about the helical axis in the first direction causes the shaftless helical blade of the auger to translate along the helical axis from the outlet of the hose towards the inlet of the hose.

  • Patent number: 10094099
    Abstract: A dual action retractable screen includes a first screen portion with a first screen portion perforated surface connected to the hinge mount via a horizontal hinge, which allows the first screen portion to rotate within a substantially horizontal plane. The screen also has a second screen portion with a second screen portion perforated surface and a latch pin. A vertical hinge connects the first screen portion to the second screen portion and allows the second screen portion to rotate within a substantially vertical plane. The screen also includes a latch mount that connects to the curb inlet and has a latch saddle that receives the latch pin. The screen operates in two modes: (1) a closed mode where the latch pin is disposed of in the latch saddle, inhibiting rotation about the horizontal hinge; and (2) an open mode where the latch pin is dislodged from the latch saddle, permitting rotation about the horizontal hinge and about the vertical hinge.

  • Patent number: 10087586
    Abstract: A system and method for treating liquid runoff from bridge decks or other types of roadways are provided. The system includes vertical scuppers positioned at low points along a length of a bridge deck. Each scupper has a removable tube fitted inside the scupper with a filtration media for treating liquid runoff such as stormwater. During rainfall events, liquid runoff gravity flows downward through the tubes and the filtration media inside the tubes so that the liquid is treated before being discharged to the environment. The tubes can be removed to periodically replace the filtration media.

  • Patent number: 10060117
    Abstract: A hydraulic separation and collection system applicable to linear street curb-inlet type drainage-chambers, independent or connected to a storm drainage network. The FIRST FLUSH COLLECTORâ„¢ is a pollutant separation and collection apparatus that can be integrated into an existing storm drain network, or be retrofitted as a component into a new or existing curb-inlet type drainage-chamber. The outfall from the FIRST FLUSH COLLECTORâ„¢ can be redirected to a conventional stormwater pollutant BMP, or be diverted to a sanitary sewer, storm drain, or combined collection system for treatment downstream. The apparatus is envisaged as a simple, easy to install prefabricated-kit utilizing a basic build-in-place separation and collection apparatus. The apparatus can be readily adapted to the needs of a given curb-inlet type drainage-chamber with minor alterations to the chambers, or to the connected existing storm drainage network.
