  • Patent number: 11067346
    Abstract: An adjusting method to adjust the liquid discharge operation from a collection tank of a cooling tower, comprising the steps of: checking an activation signal of a discharge solenoid valve (EV) of the tank; detecting a flow value of the liquid flowing between an inlet mouth and a discharge mouth of the collection tank to allow a discharge operation of the liquid contained in the tank, wherein said discharge operation is allowed in correspondence of a detection of a flow rate value of the liquid flowing between an inlet mouth and a discharge mouth of the collection tank at least equal to a reference threshold value and wherein said discharge operation is inhibited in correspondence of a detection of the liquid flow rate value that is null or lower than said reference threshold value.

  • Patent number: 10252190
    Abstract: A screen decanter for decanting liquid from a reservoir, comprising at least one rack comprising screens and baffles forming the sides of a cavity; a frame attached to the screens and baffles and providing a barrier so that liquid cannot pass from outside into the cavity without passing through the screens; a patterned perforated drain pipe inside the cavity and leading to an opening through which liquids may drain out from the cavity. The pattern of the openings counteracts the hydrostatic head within the rack such that flow through the screens is uniform at all depths of immersion in the liquid reservoir. Preferably, the screens have a porosity of about 50 micrometers.

  • Patent number: 8764407
    Abstract: A fluid level control mechanism comprising a reservoir assembly, a flow line assembly, and a resilient force assembly. The flow line assembly has a main flow line capable of passing a fluid, a diverter flow line, and a diverter valve. The diverter valve is connected to a lower end plate of the reservoir assembly via a lever arm, such that the reservoir assembly is capable of sliding along the length of the main flow line in response to a fluid level. Downward movement of the reservoir assembly opens the diverter valve and upward movement of the reservoir assembly closes the diverter valve. The resilient force assembly is attached to the main flow line and the reservoir assembly and is capable of exerting a vertical force against the reservoir assembly to close the diverter valve.

  • Patent number: 8725301
    Abstract: A method of controlling an ebb and flow watering system utilizing existing hardware commonly used in ebb and flow systems including float switches, water pumps, electromechanical timers, reservoir, control bucket, flood lines, indicator LEDs and plant containers such that the filling and draining of the control bucket is improved by accommodating for hydraulic delays, flood line restrictions, and pump limitations, while further providing constant monitoring for leaks or float switch failure, and shutting off the pumps if the same are determined.

  • Publication number: 20110308636
    Abstract: The invention is directed toward a drain float for sanitizing a condensate drain to reduce sludge and pathogens. The drain float includes a pivot shaft having a first and second end. A barbed float connects to the second end of the pivot shaft. Such barbed float includes a buoyant drum and one or more titanium barbs. The buoyant drum includes a cork filed cylinder. The one or more barbs include a bent portion and a sharpened distal end. A third component of the drain float is a tubular adaptor of a sufficient size to receive the first end of the pivot shaft. Such tubular adaptor may have an internal cavity with a diameter greater than the buoyant drum, as well as an opening which allows passage of condensate into a drain inlet. The drain float has an anti-microbial coating placed on the barbed float, pivot shaft and tubular adaptor.

  • Patent number: 8038889
    Abstract: A screen cleaning apparatus for use, for example, in connection with a discharge conduit of a sewage pumping station, may include a housing, a screen, a rake and a float. The housing may operate to contain a fluid (and/or define a container for the other components) and include a fluid inlet and a fluid outlet. The screen may be positioned in the housing and define one or more apertures. The rake may also be positioned in the housing and have one or more protrusions, with each protrusion extending into a respective aperture in the screen. The float may apply a force to the rake so that the rake moves relative to the screen and in dependence upon variations of a volume of fluid received in the housing. Accordingly, the rake may rise and fall will the fluid level to remove debris from the screen.

  • Patent number: 6474361
    Abstract: A floating weir assembly for controlling the discharge of fluid from a fluid reservoir. The weir assembly includes a buoyant body preferably comprising a sidewall surrounding a central bottom opening. A weir is provided on the inside surface of the sidewall, and a gauge is provided on the opposite side of the sidewall's inside surface. The sidewall may provide a ballast chamber for holding ballast, such as sand. By adjusting the amount of the ballast, the depth to which the body is submerged can be varied. By distributing the sand circumferentially, the body can be leveled in the fluid to ensure accuracy of the weir. Because the sidewall is partially submerged, undesirable surface matter, such as oil and debris, is prevented from entering the weir. While there are many applications for this floating weir assembly, a preferred application is in the field of sewage treatment systems.

  • Patent number: 6238577
    Abstract: The present invention provides a barrier over which waste water must flow in order to reach the outlet of a wastewater treatment plant. The barrier provided by the weir allows wastewater to exit the plant, while keeping solids that are in suspension to remain. The weir has a scum baffle mounted on its front that acts as a shield against solids that are floating on the surface of the wastewater. The self-leveling ability of the weir is provided by the use of two floats and a coupling to the outlet pipe that has rotational freedom. The floats are mounted on either side of the weir in such a way so that they are partially submerged in the wastewater. The buoyant forces that result cause the weir to align itself parallel to the surface of the water at all times. One advantage of the present invention is that it is self-adjusting, thus eliminating the need for calibration or adjustments after installation.

  • Patent number: 6224753
    Abstract: A water catchment device floating at the surface (19) of a basin comprising: a floating support (1) having a support base (3); and a skimmer (4) retained on the base (3) and comprising a skimmer body (5) which can be vertically displaced above the base (3), the skimmer body (5) having a base (7) which has at least one auxiliary passage (11) designed to be closed off by the base (3) when the skimmer body (5) is resting thereon, and a floating dish (13) which sits at the top of the skimmer body (5) during abnormal operation due to excessive buoyancy caused by inadequate filling with water, in which case the skimmer body becomes buoyant and rises above the base releasing the auxiliary passage (11) by which the water enters the skimmer body, from where it is pumped.
