  • Publication number: 20170334706
    Abstract: A fluid product dispenser is sized to removably receive a product package containing a supply of the fluid product. The product package includes an internally integrated fluid pump, and the dispenser includes a drive unit powered by flow of a fluid. Flow of the fluid powers the drive unit, which in turn drives the pump internal to the product package, resulting in dispensation of the fluid product in a product/fluid ratio that is independent of the fluid flow rate.

  • Patent number: 9700854
    Abstract: A dilute chemical solution may be prepared in response to a dispense request by combining multiple concentrated chemicals with a diluent. In one example, a target amount of diluent is dispensed into a container until a measured weight of the diluent reaches a target weight. A first concentrated chemical is also dispensed into the container until a measured weight of the first concentrated chemical reaches a target weight. The liquid solution containing the diluent and the first concentrated chemical is withdrawn from the container and applied on a second concentrated chemical that is a solid state product so as to cause the second concentrated chemical to at least partially dissolve and enter the container. In some applications, the first and second concentrated chemicals react with one another to generate an active molecule in the chemical solution that is not present in either of the two concentrated chemicals.

  • Publication number: 20150094369
    Abstract: Methods and systems for temperature-controlled, on-site generation of peracids, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions are disclosed. In particular, methods for using an adjustable biocide formulator or generator system overcome the limitations of temperature on the kinetics of the peracid generation and/or peracid decomposition inside an adjustable biocide formulator or generator system. The methods include the controlling of the temperature of at least one raw starting material, namely water, to improve upon methods of on-site generation of peracids. The methods allow for the generation of user-selected chemistry without regard to the ambient temperatures of the raw starting materials and/or the biocide formulator or generator system.

  • Patent number: 8980636
    Abstract: A system and method for performing automated titrations. An automatic titrator utilizes control devices and sensors adapted for various chemical reactions to perform titrations and determine the content of a desired component of a solution. Batch and continuous mode titrations are possible. Titrant is added to a sample either in varying amounts or rates and a titration endpoint is observed via sensors. Control devices detect when the titration endpoint occurs and calculates the desired content. Various reactions within the solution may be suppressed in order to titrate isolated components individually.

  • Patent number: 8944286
    Abstract: A dispensing system and methods employed therein uses optical displacement sensing to control dispensation of one or more products. An optical displacement sensor measures displacement of a load beam supporting a vessel from which the product is to be dispensed. The displacement of the load beam is related to the amount (weight) of the product remaining in the vessel. The system may thus control dispensation of the product based on the optical displacement measurements.
