  • Publication number: 20140042242
    Abstract: A chemical delivery system and related methods of use in which a multi-port manifold is utilized to distribute a plurality of mixed chemical solutions. The multi-port manifold includes a single fluid inlet for receiving a diluent supply that is routed to a plurality of individual outlet ports. A venturi injector module including a valve assembly, a venturi mixing assembly and a latch assembly is fluidly coupled to each outlet port for individually controlling flow of the diluent through the outlet port. The venturi mixing assembly generally comprises a quick-connect projection for coupling the venturi mixing assembly to the outlet port. The latch assembly functions to retain the fluid connection of the venturi mixing assembly and the outlet port. The latch assembly and venturi mixing assembly generally include corresponding portions of a keyway shape that ensures that only the proper venturi mixing assembly is attached to the proper outlet port.

  • Patent number: 8641830
    Abstract: Apparatus and related methods for continually measuring and dispensing precise amounts of bulk chemical in a car wash application. A gravimetric dispensing assembly can include a load cell and a syringe dosing pump that is suspended below the load cell such that an entire mass of the syringe dosing pump is communicated to the load cell. In this manner, the load cell can measure the actual mass of chemical being dispensed from the syringe dosing pump on a continuous basis without solely relying on the rated volumetric capacity of the syringe dosing pump. The syringe dosing pump can be driven by a stepper motor that can be pulsed as directed by a controller so as to maintain, increase or decrease an amount of bulk chemical being dispensed from the syringe dosing pump.

  • Patent number: 8322367
    Abstract: An expandable chemical delivery system sharing a common bulk fluid inlet and bulk fluid flow path to direct a bulk fluid through one or more selected chemical eductors. Each chemical eductor is slidably insertable into an eductor port on the manifold body such that rotation of the chemical eductor is not required for installation. After installation, the orientation of the chemical eductor can be rotatably adjusted so as to avoid interference with adjacent chemical eductors. Delivery of a bulk fluid to each chemical eductor is controlled via a corresponding valve assembly that selectively allows or blocks flow of the bulk fluid from the bulk fluid flow path to the corresponding chemical eductor. The manifold body can include a plurality of individual manifold bodies approximated with a coupling system to define the bulk fluid flow path. Alternatively, the manifold body can comprise a single fabricated body for high pressure operation.

  • Patent number: 8246883
    Abstract: A filter cartridge includes a one-piece housing having a port and a filtration element disposed in the housing. The filtration element is a coherent filter block that can be larger in cross dimension than the port. The filtration element can be a coherent filter block that generally conforms to the shape of the hollow interior, but is slightly smaller than the hollow interior so as to define a gap between the filtration element and the inner surface. One method for constructing a filter cartridge includes providing a housing having a hollow interior and at least one port, introducing a granular material into the hollow interior via the port, and transforming the granular material in the hollow material into a coherent filter block. Another method for constructing a filter cartridge includes providing a filtration element in the form of a coherent filter block, and overmolding a housing around the filtration element.

  • Patent number: 8157972
    Abstract: An electrolytic water treatment system improving upon the electrode life of electrolytic oxygen generators by reducing mineral precipitation and fouling that typically occurs in water treatment systems. The electrolytic water treatment system can include a softened water bypass stream into which a flow-through electrolytic element can be positioned. By eliminating exposure of the electrolytic element to hard water, scale formation on electrodes can be significantly reduced such that polarity reversal cycles of the electrolytic element decrease in frequency.

  • Publication number: 20110192433
    Abstract: A system for controlling and monitoring the chemical usage in a car wash systems that form an aqueous cleaning solution by diluting a cleaning chemical concentrate in a process water stream to form. Level sensors are mounted to the bulk containers containing the chemical concentrate to measure and track the usage of the chemical concentrates. The usage data is collected and used to adjust flow rate controllers controlling the dilution of the concentrate into the process water stream. The system can be integrated into continuous processes where the aqueous cleaning solution is dispensed immediately after production and batch processes where the cleaning solution is stored temporarily before being dispensed onto a vehicle.

  • Publication number: 20080237060
    Abstract: Apparatus and related methods for increasing dissolved oxygen levels in water to remove iron and/or manganese. A dissolved oxygen treatment system includes a control system having a power supply and an electrode placed within a water chamber. At the electrode, water is converted into hydrogen gas and oxygen gas, wherein the oxygen gas remains in solution and increases the concentration of dissolved oxygen gas in the water. The dissolved oxygen treatment system can be manually configurable wherein the electrode is selectively wired to use either portions of or the whole electrode based upon testing of the water source with a dynamic electrode test system. Alternatively, the dissolved oxygen treatment system can include a smart controller, a variable power supply and a fixed size electrode, wherein the smart controller continually controls the power output to the fixed size electrode so as to control the amount of dissolved oxygen that is generated.
