A powdered and liquid chemical distribution system for distributing powdered and liquid chemicals. The system includes a transport module having a plurality of chambers arranged in series to automatically distribute both a powdered chemical and a liquid chemical to a point of use along a single line, wherein the plurality of chambers share a chamber wall.

Powdered and liquid chemical dispensing and distribution system

A metering and dispensing closure for a container. A rotor and a movable member rotate in conjunction with a cap member to afford accurate measuring of a powder material and dispensing of it. The rotor, the movable member, and the container cap afford a consistent measuring of the powder material, as well as provide a variety of drive members which can be utilized with the dispensing closure.

Metering and dispensing closure

A metering and dispensing closure for a container wherein two rotatable disks rotate in conjunction with a stationary cap member to afford accurate measuring of a powder material and dispensing of it. The disks and the container cap afford a consistent measuring of the powder material, as well as provide a variety of drive members which can be utilized with the dispensing closure.

A method for distributing powdered and liquid chemicals. The method includes introducing water into an upper end of a measuring chamber, injecting liquid chemical through an inlet located at a lower end of the measuring chamber into a chemical chamber that is fluidly coupled to a lower end of the measuring chamber until a desired volume of the liquid chemical has been introduced, pumping the desired volume of liquid chemical and at least some of the water to a washer, inserting water and a desired dose of a powdered chemical into the upper end of the measuring chamber, and transporting the powdered chemical and at least some of the water to the washer.

The chemical distribution system () includes at least a first chamber that is fluidly coupled to a second chamber below it, which is in turn fluidly coupled to a manifold below it. In use, water and a powdered chemical are introduced into the first chamber. Liquid chemicals, however, are injected into the second chamber through multiple chemicals inlets in the second chamber. A pressure sensor fluidly coupled to the first chamber is used to accurately measure dosages of the liquid chemical. Once the accurate dosages have been determined, the powdered and/or liquid chemicals are distributed through one of multiple manifold outlets and along a single line ((),()) to one of multiple washing machines ((),()).

Prior to adding detergent or chelant, the conductivity of water in a washing chamber is measured. The maximum concentration of hard water ions that could correspond to the measured conductivity is determined, i.e., it is assumed that all of the conductivity is from calcium and/or magnesium ions in the water even though other ions may in fact be contributing to the measured conductivity. Enough chelating agent is added to the chamber to sequester this maximum concentration of hard water ions and the conductivity is measured again. Using the two conductivity measurements, the actual concentration of hard water ions is determined. A chelant factor based on the actual concentration of hard water ions is then used to determine the amount of chelant to be added for subsequent wash cycles to sequester all of the hard water ions.

Method and system for measuring water hardness

A method of determining one or more operational parameters of a washing system having a wash tank to which water and material are added. In one embodiment, the method includes monitoring a concentration of material, which is decreased at least partially due to water being added to the wash tank. The method also includes maintaining the concentration of material by dispensing material into the wash tank during a material dispensing operation. Additionally, the method includes generating a parameter indicative of a rate at which the material is dispensed during the material dispensing operation. The method also includes determining a presence of a water flow abnormality based at least partially on the generated parameter.
