Abstract: A storm water drain filter including a collapsible frame supporting a filter bag. The filter may be installed in a stormwater drain pit to capture contaminants and particulate matter before it enters a stormwater drain. The collapsible frame is light weight, compact, simple and inexpensive. The filter bag is secured to the frame so as to maintain its shape and avoid deformation. There is also disclosed a method of installing a stormwater drain filter in a stormwater drain pit to provide an effective seal between the stormwater drain filter and the pit.

Abstract: A wastewater lifting station is provided, in which at least one solids collection tank contains at least one screen for guiding wastewater therethrough and retain solids. The screen divides the solids collection tank into a region containing solids and a region free of solids, and is connected in a pivotable manner by at least one hinge to a flange of the solids collection tank. The screen in an edge region away from the hinge has a rake of comb-type webs and holes that are open on one side in the screen plane. The wastewater containing solids flows through a feed into the collection tank, is filtered through the screen, and the wastewater that is free of solids is collected in a tank downstream. When the wastewater lifting station pumps, the wastewater that is free of solids is pumped by a pump in counterflow through the screen into a pressurized line while the feed is shut off by a check valve, and the screen pivots about the hinge and is back-flushed during the process. Reliable cleaning of the screen, even of fibers, is achieved during pumping owing the rake shape and the pivoting of the screen.

Abstract: A treatment device for stormwater is provided that comprises a container which in use contains a growing medium and a hydrodynamic separator located within the container. The hydrodynamic separator comprises a separation chamber, an inlet duct extending from the outside of the container to the separation chamber, a solids outlet; and a liquid outlet that opens into the container. In use, liquid flow containing solids enters the separation chamber through the inlet duct and is caused to swirl within the separation chamber, thereby causing solids to exit the separation chamber through the solids outlet and liquid to exit the separation chamber through the liquid outlet and to flow into the growing medium.

Abstract: A stormwater treatment unit comprising a containment vault having an inlet and an outlet separates debris from a flow of stormwater through the unit. The water flow is controlled by a wall which directs flow from the inlet to the outlet through a reservoir of fluid in the unit. Debris separation by density occurs whereby lighter elements such as oil float on top of the fluid and heavier elements such as sediment collect at the bottom of the unit or in collectors in the reservoir. A wire mesh, deflector, and/or ripple boards placed beneath the inlet further increase efficiency of the separation, and a vent pipe is placed above the outlet to release pressure built up in the outlet during operation. A stormwater treatment system and method of retrofitting an existing stormwater trunk line locates the stormwater treatment unit in an off-line position from an existing drainage trunk line.

Abstract: A grit removal unit including an influent channel directing wastewater with grit into a round grit removal chamber and an effluent channel receives wastewater output from the chamber. A divider wall extends upwardly between the sides of the influent channel, and gates at the upstream end of the divider wall are adjustable to selectively open channel portions on opposite sides of the divider wall. An output guide member is mounted to allow selective adjustment of output flow opening width “c” to the effluent channel. The output guide member has a horizontal bottom extending from the chamber into the effluent channel across the width of the output opening, and a guide wall extending upwardly from the guide member bottom. The guide wall has a forward end spaced from the chamber annular vertical wall to define the output flow opening width therebetween.

Abstract: Devices, apparatus, systems, and methods for retrofitting or providing new water treatment vaults and chambers, with a floatable skimmer on tracks above a solid shelf that constricts and restricts water during low and medium flows for maximum detention time to allow for greater storm water treatment, and for high flows allows for the skimmer to automatically adjust to allow for greater conveyance of storm water flow. The skimmer can have float(s) across an upper edge with side edges having both centering and load bearing wheels that slide up and down within tracks that are mounted to side walls of storm water treatment chambers and vaults. Additional embodiments include multi-chamber vaults and chambers with baffles separating sediment chambers. Additionally screen treatment systems can be used with the chambers and vaults. Additionally, the skimmer panels can be positioned so that lower edges can sit on top of outer edges of the shelfs, or form a gap between the top of the outer edge of the shelf and the lower edge of the moveable panel, or have a gap between a hanging down skimmer panel and a front edge of the shelf.
