A method and apparatus for obtaining a product chemistry from a solid block is provided. The product is housed within a dispenser, which utilizes a liquid and a gas to erode the block and produce a concentrate solution. The liquid and gas characteristics can be adjusted in the field to achieve a predetermined concentrate level in the solution. The introduction of air into the dispenser saves water, while producing higher concentrate levels.

A manifold has a fluid inlet, a plurality of fluid outlets, a movable conduit member, a first drive mechanism, and a control module in which the conduit member has a fluid path therethrough, in which the fluid inlet is fluidly connected to a first end of the fluid path, in which the conduit member is mounted for movement on a support member, and in which the first drive mechanism is configured to move the conduit member on the support member to selectively associate a second end of the fluid path with one of the plurality of fluid outlets according to commands issued by the control module.

A foam generator, in particular for a motor vehicle washing installation, includes a foam generation chamber having at least one inlet for water, surfactant and gas, in particular compressed gas, and one outlet for foam, and contains a fluid-permeable bed of loose particles. The bed fills the foam generation chamber sufficiently to prevent fluidization of the bed.

Systems and methods are described for dissolving ammonia gas in deionized water. The system includes a deionized water source and a gas mixing device including a first inlet for receiving ammonia gas, a second inlet for receiving a transfer gas, and a mixed gas outlet for outputting a gas mixture comprising the ammonia gas and the transfer gas. The system includes a contactor that receives the deionized water and the gas mixture and generates deionized water having ammonia gas dissolved therein. The system includes a sensor in fluid communication with at least one inlet of the contactor for measuring a flow rate of the deionized water, and a controller in communication with the sensor. The controller sets a flow rate of the ammonia gas based on the flow rate of the deionized water measured by the sensor, and a predetermined conductivity set point.

An mixing device includes at least one mixing chamber, a memory, a processor coupled to the memory, and a set of instructions stored on the memory and configured to be executed by the processor. The processor is configured to determine a custom mixing recipe comprising a plurality of ingredient types and corresponding amounts for each of the plurality of ingredient types. The processor is further configured to insert the plurality of ingredient types into a first mixing chamber. A first amount of a first ingredient type and a second amount of a second ingredient type are inserted according to the custom mixing recipe. The processor is further configured to mix the plurality of ingredient types in the first mixing chamber. The processor is further configured to dispense a mixture of the plurality of ingredient types as at least one of a vapor, a fine powder, a mist, and a liquid.

A dosing system includes a dispensing apparatus that receives first and second fluids from respective input sources. The first fluid is modified by an electrolytic cell assembly to produce an output fluid, and the second fluid flows through the electrolytic cell assembly or bypasses the electrolytic cell assembly. The dispensing apparatus includes a cartridge system supporting chemical cartridges having a concentrated solution and a mechanism to dispense the solution. At least two chemical cartridges with different concentrated solutions, and each chemical cartridge selectively fluidly communicates with the output fluid and the second fluid. The dispensing apparatus also includes an interface and a controller programmed to perform instructions including receiving a request from the interface, mixing the concentrated solutions and the first or second fluid input sources, and dispensing a product defining a dilution including the first and second fluid input sources and the chemical solutions.

A foam generator includes a foam generation chamber which contains or consists of a porous filling material and which has at least one inlet for supplying a liquid and a gas, and an outlet for discharging the foam generated in the foam generation chamber. The mean pore diameter of a cross-sectional area of the filling material decreases from the inlet to the outlet continuously or discretely.
