  • Patent number: 8999170
    Abstract: A biological wastewater treatment system includes an equalization tank for sending a defined first portion of the wastewater to a submerged membrane filter. When the quantity of the received wastewater exceeds the defined first portion, a second portion of wastewater, formed from the wastewater that exceeds the defined first portion, is sent to a filtration process. The filtration process includes adding a flocculating agent to the second portion entering filtration, filtering the second portion, thereby producing retentive waste including flocculated material, and then sending the retentive waste to the submerged membrane filter.

  • Patent number: 8961752
    Abstract: A filter device purifies fluids, especially fuels contaminated with organic substances. Hydroxyl radicals are formed from water molecules contained in the fluids by a separating device (10, 14, 22). The hydroxyl radicals oxidize the impurities, especially organic substances, as much as possible and convert them into compounds such as CO2.

  • Patent number: 8940170
    Abstract: A dual-chambered horizontal flow water treatment system and method provides a first chamber with a first filtration system connected with a second chamber with a second filtration system in a horizontal orientation, such that influent water first passes through the first chamber and then passes through the second chamber. The influent water moves through the first chamber and second chamber in a horizontal flow path to provide for pre-filtering with the first filtration system before traveling through granular media in the second filtration system.

    Abstract: An expansion ring has multiple adjustable expansion joints and plural bolts around the periphery of the ring that have pointed tips that bear into the sides of an existing manhole. The combination of the expansion joints and bolts allows the expansion ring to be securely affixed in the manhole. A filter basket assembly is suspended from the expansion ring into the manhole. Plural expansion rings with filter basket assemblies are strategically located along a clean-out route so that a full Vactor truck or sweeper may be emptied—decanted—into the filter basket assemblies on-route rather than at a traditional treatment plants.

    Abstract: A stormwater treatment system includes water treatment media that defines a helical flow path within a conduit. The water treatment media may include a plurality of helical water treatment media components that are constructed and arranged to seal against an inside surface of the conduit. The individual helical water treatment media components may be installed in situ within the conduit when the conduit is positioned within a chamber having an access opening, and periodically removed and replaced by passing the components to the access opening. The components further may have a flexible frame, which allows the water treatment media to dynamically adjust to swelling of the filtration media and other forces that may occur during use. The performance of the system may be adjusted by adjusting the helical pitch of the helical water treatment media components.

  • Publication number: 20140054236
    Abstract: A gate valve curb box strainer collects debris introduced through a street level cover, minimizing debris build up in the gate valve access pipe of the curb box. Water passes through the curb box strainer, while the strainer catches debris that naturally builds up over time via the street level cover. When a worker removes the cover to exercise the valve, he need only lift the gate strainer out of the access pipe and shake the debris out of it. There is no need to take extra time digging out or vacuuming out the debris. In an emergency situation such as accessing the valve for a fire hydrant or during a water/sewer main break, this could save valuable time. After the valve has been exercised, the empty gate valve curb box strainer is dropped back in place prior to covering the gate valve curb box with the street level cover.

  • Patent number: 8658044
    Abstract: A stormwater filter cartridge includes a housing with internal filter medium disposed along a flow path between a water inlet and a filtered water outlet. A solid wall float tube in a drainage space has an open lower end and open upper end and is movable between a lowered position and a raised position. As the housing fills, water level in the housing rises to cause the solid wall float tube to move to the raised position and a negative pressure draws fluid through the filter medium. As water level outside the filter cartridge drops, air enters the housing and causes the solid wall float tube to drop to the lowered position, and filtered water in a fluid reservoir backflows through the filter medium while air enters the housing by passing upward through the solid wall float tube so as to enhance rate of backflow.

    Abstract: Devices, apparatus, systems and methods for preventing backflow current problems which often have caused debris and litter to pass out of screen type baskets used in storm water treatment systems. A half size or full size pivoting panel at the input end of a basket screen system placed in a storm water treatment chamber can downwardly divert incoming storm water so as to prevent back flow currents from being formed. The pivoting panel can work well during high flow conditions. A half size or full size pylon located in the input end of the basket screen can split and divert incoming storm water to also prevent back flow currents from also being formed. The pylon can work well during low flow conditions. Also, both the half pivoting panel and the half pylon can both be used at the input end of the screen basket. Still furthermore a gap in the floor before the input end of the screen basket can allow for sediment coming to pass down and collect beneath the screen basket.

  • Patent number: 8323506
    Abstract: An apparatus for and method of filtering hydrocarbon contaminated water, which may be used in drainage openings in parking lots and containment areas for large sources of hydrocarbons to remove hydrocarbons from hydrocarbon contaminated water. The apparatus has a filtration compartment which filters out debris which may clog the treatment compartment. A pre-filtration and means for melting snow may be incorporated. The treatment compartment contains a hydrocarbon absorption media which absorbs any hydrocarbons present in the water rendering such water substantially hydrocarbon-free for discharge directly into a stream or groundwater. If a hydrocarbon spill occurs, the hydrocarbon absorption media forms a plug which seals off the flow of contaminated water. A hydrocarbon solubilizing material capable of effectively removing sheen in a first pass may be disposed as a top layer over the hydrocarbon absorption media.

  • Patent number: 8303816
    Abstract: A horizontal flow water treatment method and wetland biofilter apparatus provides a chamber with impermeable outer walls spaced away from permeable interior walls of a media filtration bed such that a catch basin is formed between the outer walls and the interior walls. The catch basin creates an open area around the perimeter of the interior walls for influent water to fill within the open area on all sides before penetrating the filtration media, providing a large surface area for influent water to interact with the media filtration bed. The influent water enters the catch basin in a horizontal flow path to provide for pre-settling of particulates before making contact with the filtration media. The biofilter design increases the available surface area of the media filtration bed by up to four times for a given volume of water, and thereby minimizes the loading or infiltration rate on the media filtration bed.
