    Abstract: An easy to install and fish safe skimmer assembly for ponds and other water features is provided. The skimmer assembly includes a skimmer housing having an upper portion and a lower portion. The upper portion is substantially open and in fluid communication with the water feature in a manner such that fish in the water feature can swim in and out of the upper portion of the skimmer housing without being trapped by a physical barrier. The lower portion is enclosed and is in fluid communication with a conduit for transporting filtered water back into the water feature. The skimmer assembly further includes a barrier that separates water within the skimmer, a debris collector, and a floating weir disposed in the debris collector and moves in a vertical direction relative to the skimmer housing when a suction force is applied to force water to flow through the skimmer housing.

    Abstract: This disclosure is directed to systems for separating a target analyte from a suspension. A suspension is added to a tube. A float is also added to the tube, and the tube, float, and suspension are centrifuged together, causing the constituent components of the suspension to separate into different layers along the axial length of the tube according to their specific gravities. The float has a specific gravity that positions the float at approximately the same level as a layer containing the target analyte, when the tube, float and sample are centrifuged. Prior to isolation, the material may be located between an outer surface of the float and an inner surface of the tube, or within a central bore that extends longitudinally through the float. The target analyte may then be drawn into a compartment within the float, thereby isolating the target analyte from the other suspension constituents.

  • Patent number: 8268167
    Abstract: Separating apparatus, for separating a substance from a liquid on which the substance can float, comprises: a separation chamber; an inlet adapted to convey a supply comprising the substance and the liquid into the separation chamber; and an outlet adapted to convey liquid collected in the separation chamber out of the separation chamber. The inlet is arranged such that, in use, the supply emerging from the inlet into the chamber is directed upwardly into the chamber, and the apparatus further comprises venting means arranged to convey gas out of the chamber. The apparatus may further comprise a floating pick up connected to a pump for pumping the supply to the separation chamber. In certain examples a non-floating pick up is used, comprising an elongate hollow body with a pick up inlet mouth in the form of a vertical slot extending along a length of the body.

  • Patent number: 8192616
    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.

  • Patent number: 8110099
    Abstract: A filter assembly for use in filtering stormwater includes a bottom including a boss that includes a rib extending laterally along an inner surface of the boss. The rib includes a locking portion that mates with a corresponding locking portion on a peripheral surface of a connection to an outlet conduit for securing the bottom to the connection thereby inhibiting rotation of the bottom relative to the outlet conduit. A center tube is secured to the bottom using a locking mechanism that inhibits relative movement between the bottom and the center tube. The center tube is in communication with an opening in the bottom and a hood is secured to the center tube. A filter medium is located between the hood and the center tube.

  • Patent number: 8075783
    Abstract: A system and method for remediating a body of water and collecting suspended and dissolved solids therefrom are provided. The system includes a water-impervious lining positionable in a depression in or adjacent a body of water. The lining and depression define a treatment vessel, which includes a treatment portion, an outlet portion for containing treated water, and an outflow weir between the treatment portion and the outlet portion. Water to be treated is transported from the water body to the treatment portion. An entrapment element is delivered and mixed into the transported water, the entrapment element for capturing suspended and dissolved solids in the transported water and effecting a separation between the captured solids and water cleansed therefrom. The captured solids can be removed from the treatment basin, and the cleansed water can move through a channel in the outflow weir into the outlet portion.

  • Patent number: 8057665
    Abstract: Disclosed are a cold water tank and a water treatment apparatus. The cold water tank includes a tank body, a water inlet pipe provided at the tank body to convey water into the tank body, a water outlet pipe provided at the tank body to convey the water out of the tank body, and including an air vent hole, and a floating member movably provided at the water outlet pipe to block the air vent hole when the water filling the tank body reaches a height of the air vent hole. The water in the upper portion of the tank body is prevented from passing through the air vent hole and draining through the water outlet pipe, thereby preventing the cooler water in the lower portion from mixing with the hotter water in the upper portion. Only the cooler water in the lower portion can be supplied to a user.
