  • Patent number: 8889007
    Abstract: The present invention is a wastewater treatment system utilizing a recirculating filter system comprising sand, gravel, or synthetic media. Septic effluent is continuously, or approximately continuously, dosed under pressure to the treatment media through pressure compensating drip irrigation emitters. The system comprises a commonly known septic tank and recirculation tank. Septic tank effluent is collected in the recirculation tank, from which it is continually dosed by means of a pump to the top of the treatment media of the recirculating filter through pressure compensating drip emitters. Continuous dosing of diluted residential septic tank effluent through drip irrigation emitters provides a slow consistent application of liquid rich in organic material and pathogens over the treatment media. The treated effluent is then recirculated if water is low or went to final disposal.

    Abstract: A storm water catch basin hazardous liquid valve that is automatically responsive to the presence of hazardous liquids in storm water run-off, the valve utilizing a hydrophobic barrier member to separate hazardous liquids from water. Collection of a sufficient amount of hazardous liquids across the hydrophobic barrier member initiates a float release member to seal off the catch basin. In the neutral or non-activated status, the storm water run-off enters the catch basin, passes through the valve assembly and out through the storm water conduit system in normal manner. When a hazardous liquid, such as oil, gasoline, chemicals, etc., is present in the storm water run-off above a threshold amount, the valve activates to close off the catch basin such that the storm water run-off is precluded from entering the storm water conduit system.

  • Publication number: 20110168608
    Abstract: A water treatment apparatus having a vessel defining a chamber adapted to contain a water treatment chemical over which a dosing liquid can flow from an inlet to form a dosing reservoir at the bottom of the vessel. A supply of dosing liquid is connected to the inlet. The interior of the vessel communicates with a conduit along which an entraining pressurized flow of water can be fed for treatment and via an opening in the conduit that is connected to a bottom outlet of the vessel. A venturi is located in the conduit adjacent the opening so that the velocity of the pressurized water is increased as it passes over the opening and entrains a dosing stream from the dosing reservoir into the pressurized flow. The venturi also applies suction to the interior of the vessel, which draws dosing liquid into the vessel from the supply.

  • Patent number: 7892422
    Abstract: A pressurized wastewater effluent chlorination system including a treatment tank defining a contact chamber and an aeration chamber. The treatment tank receives wastewater effluent. The system includes a pressure vessel within a liquid chlorine storage container positioned in or near the treatment tank. Preferably, the pressure vessel is a floating vessel having a check valve at its bottom, enabling the vessel to fill with a predetermined amount or measured charge of chlorine depending on the position of a float on the vessel. In response to a timer control or float switch, a valve operates to communicate air pressure from a compressor to the vessel to displace the measured charge of liquid chlorine into the wastewater effluent in the contact chamber. Effluent flow and air discharge into the contact chamber enhances mixing of the chlorine and the effluent.

  • Publication number: 20100256595
    Abstract: A separation device including a first buoy, a second buoy, a first valve, and a second valve. The first buoy is mounted to a buoy guide post and slidably mounted within a separation chamber. The second buoy is slidably mounted to the guide post and movable between a first position and a second position. The second buoy closes the first valve and opens the second valve when in the first position. The second buoy opens the first valve and closes the second valve when in the second position. The second buoy has a density such that after spinning the device for a suitable period of time a first component of the composition is isolated between the first buoy and the second buoy and a second component of the composition is isolated between the second buoy and the end of the separation chamber that is opposite to a port.

  • Publication number: 20100147752
    Abstract: A screen system having first and second side members, each having a locking gear reversibly movable from a locked position to an unlocked position. A screen is coupled to the side members. The screen has openings and is rotatable from a closed position to an open position. The screen is engagable with the locking gears to preventing the screen from rotating from the closed position to the open position. A trigger plate is movably coupled to the screen, rotates from a first position to a second position and is engagable with the locking gears to prevent the locking gears from moving from the locked position to the unlocked position. The trigger plate disengages with the locking gears when water flows against it, allowing the locking gears to move from the locked position to the unlocked position and the screen to rotate from the closed position to the open position.

  • Publication number: 20100059426
    Abstract: This invention involves a liquid-liquid separation device, which includes a centrifugal cylinder. The centrifugal cylinder maintains a liquid inlet/outlet, and centripetal float valve inside, which is mounted on the wall of a cylinder that produces the centrifugal force. This invention allows the liquids of various densities to enter the centrifugal cylinder; under the action of centrifugal force, the liquid medium of the highest density approaches to the cylinder wall first, while the liquids of lower densities follow in sequence; when the inward buoyant force that the float bears in the liquids of various densities is over the outward centrifugal force generated due to its own mass, the float will move inwards to open the passageway and discharge the heavy medium deposited on the cylinder wall, thus achieving the automatic separation.

  • Publication number: 20100038292
    Abstract: An apparatus that combines desalination and pressure washing. The apparatus includes separate inlets for seawater and for freshwater. The apparatus includes a first diverter valve to selectively permit the flow of seawater or freshwater into the apparatus. The apparatus also contains a second diverter valve for directing the flow of seawater or freshwater to a pressure-washer outlet for pressure washing or directing the flow of seawater to a desalination assembly such as a reverse-osmosis (RO) membrane for desalination. The apparatus contains one or more pumps sufficient to generate fluid pressure for pressure washing and generating a driving pressure across the desalination assembly. A variable frequency drive system may be included in the apparatus to regulate the RO pump flow rate across a fixed orifice thereby regulating driving pressure and in turn the freshwater production rate from the RO system.

  • Patent number: 7635431
    Abstract: A flow control device for the drain lines of a septic system interrupts the flow in the event the proximate water table rises to a level of over-saturation resulting in the effluent flow being directed to the remaining drain lines. Each drain line is provided with a control box having a float controlled inlet valve having an open position allowing flow to the drain line. When the drain line cannot handle the required flow rate or when the proximate water table rises, the float shifts the valve toward a closed position, thereby redirecting the flow to the remaining lines.
