  • Publication number: 20080006586
    Abstract: Monochloramine is efficiently manufactured by introducing controlled quantities of an ammonia source and a chlorine source in a small side-stream of water in a small diameter pipe under turbulent flow conditions. The ammonia source and chlorine source can be injected in either order and are separated by a sufficient distance to ensure that the first chemical is adequately diffused throughout the water prior to the injection of the second chemical. A sufficient length of a mixing chamber insures that turbulent flow is maintained for a length of time sufficient to thoroughly mix the two chemicals to produce monochloramine. This mixing technique allows for the manufacture of high concentrations of monochloramine at atmospheric pressure without off gassing.

    Abstract: The present invention discloses a method and apparatus for separating particles and dissolved matter from a fluid stream. Specifically, the present invention includes a first pressure source which transports untreated fluid into a separator annulus with a filter element disposed therein. The untreated fluid is placed under appropriate pressure sufficient to produce turbulent flow, increased particle kinetics and/or cavitation physics allowing the desired fluid to penetrate and pass into and through the filter media. The filtered fluid is then transported to a collection tank. The contaminant particulate matter retained on the exterior of the filter media may be removed by the instantenous reverse pressurization of the separator annulus by a second pressure source thereby removing the contaminant particles away from contact with the filter media, and which may then be transported to a waste collection tank or a concentrator for further treatment.

  • Patent number: 7156995
    Abstract: Mineral contaminants are removed from water in a system in which water is sprayed into an air head at the top of a tank through a diffuser and withdrawn through a pick-up tube. A solenoid valve operates to allows air from a compressor to flow into the top of the tank through a shuttle valve which is opened by the air pressure. Simultaneously a drain valve connected to the shuttle valve opens a drain, venting water and air from the tank. The shuttle valve, closed by the solenoid valve, closes the air supply line and connecting the shuttle valve to atmosphere, and pressure within the aeration tank can close the shuttle valve, which causes closing of the drain valve. The part of the valve which opens the drain is made responsive to excess pressure within the air tank to open the drain and so acts as a pressure relief valve.

  • Patent number: 7063794
    Abstract: A water treatment apparatus dissolving an oxidizer in wastewater at a fast speed and at a high efficiency to decompose substances at a high decomposition rate. The apparatus includes an ultraviolet radiation part having an elongated tubular configuration, and receiving an axially extending ultraviolet radiation unit with a space between an inner peripheral surface of the ultraviolet radiation unit and the ultraviolet radiation unit to pass wastewater; and an oxidizer mixing part disposed adjacent to and upstream of the ultraviolet radiation part for mixing an oxidizer with the wastewater. The ultraviolet radiation unit irradiates the wastewater with ultraviolet light to decompose the substances to be treated in the wastewater.

  • Patent number: 7048853
    Abstract: Arsenic is removed from water and other aqueous feeds by (1) treating the feed with a compound containing cerium in the +4 oxidation state, preferably cerium dioxide, to oxidize arsenic in the +3 oxidation state to arsenic in the +5 oxidation state and (2) removing the arsenic in the +5 oxidation state from the aqueous phase, normally by contacting the treated feed with alumina or other precipitating agent containing cations in the +3 oxidation state.

  • Patent number: 7028849
    Abstract: Screen apparatus comprising a screen (10) which allows fluid to pass through it whilst providing a barrier to non-fluid matter in the fluid. A jet outlet (22) is arranged to direct a jet of fluid across that side of the screen (10) on which such matter would otherwise tend to collect when the apparatus is in use.

  • Patent number: 7018531
    Abstract: An oil-conditioning filter, for use with an internal combustion engine, includes a mechanical filter element and a central additive cartridge, for gradually dispensing an oil additive over time. The additive cartridge has a beneficial oil-conditioning agent contained therein. The additive may be provided as a solid block within a storage chamber of the cartridge, or may be a plurality of pellets. Central placement of the cartridge allows for fluid filtration through the mechanical filter element before the additive is added thereto, reducing the likelihood that the additive will be filtered out prematurely upon its initial release. An additive cartridge for installation in an oil filter is also described, including a baffle portion and a storage chamber. Alternative exemplary embodiments of the additive cartridge may include a cylindrical shell, a basket which is operatively attached to an oil filter center tube, or a porous center tube.

  • Patent number: 7008538
    Abstract: A process for treating wastewater and a system for practicing the process includes: providing a plurality of zones within a single vessel wastewater treatment system; feeding wastewater into the system; maintaining an aerobic zone in the upper central portion of the vessel; feeding air into the aerobic zone for oxygenation and creating an upflow; maintaining an annularly disposed anoxic zone about said aerobic zone; causing the upflow from the aerobic zone to produce a downflow in the anoxic zone; causing at least a portion of the downflow from the anoxic zone to pass into the upflow of the aerobic zone; maintaining an annularly disposed clarification zone about said anoxic zone for clarified liquid, including an upflow; causing at least a portion of the downflow from the anoxic zone to pass into the upflow of the clarification zone; maintaining a facultative transition zone below the upper aerobic, anoxic and clarification zones; maintaining an anaerobic zone below the facultative zone for absorbing solids s

  • Patent number: 6984319
    Abstract: An environmentally friendly acid neutralizing filter cartridge is adapted to be mounted in a cartridge mounting body of an engine oil circuit for filtering particulates and neutralizing acid in oil. The filter cartridge comprises a support housing that comprises substantially no metal parts such that the filter cartridge can be readily incinerated. A full flow particulate filter and a bypass particulate filter are arranged in the support housing. A bed of acid neutralizing particles is contained in the support housing. The housing is configured such that a predetermined primary flow path is defined through the filter cartridge that passes through the full flow particulate filter and bypassing the bed of acid neutralizing particles; and a predetermined bypass path is defined through the filter cartridge that passes, in sequence, through the bed of acid neutralizing particles and the bypass particulate filter.
