Methods, systems, and devices for freeze point suppression cycle control are provided in accordance with various embodiments. For example, some embodiments include a method of freeze point suppression cycle control. The method may include flowing a liquid to a first sensor; the liquid may include a mixture of a melted solid and a freeze point suppressant. The method may include determining an indicator value of a freeze point suppressant property of the liquid utilizing the first sensor. The method may include controlling a flow of the liquid to a separator utilizing a flow controller based on at least the determined indicator value of the freeze point suppressant property of the liquid; the separator may form a concentrated freeze point suppressant from the liquid. Freeze point suppression cycle control systems are also provided.

A floor cleaning machine is provided. The floor cleaning machine includes a cleaning head configured for cleaning a floor surface with a cleaning solution. A collection mechanism is configured to collect used cleaning solution following use by the cleaning head. A conduit fluidly connects the collection mechanism with a recovery tank. The conduit is configured to convey a flow of the used cleaning solution from the collection mechanism to the recovery tank. A defoaming system is positioned proximate the recovery tank and includes a solid chemical defoaming form. The solid chemical defoaming form is configured for dissolution within the flow of the used cleaning solution. The flow of the used cleaning solution is directed over the solid chemical defoaming form and into the recovery tank.

A floor cleaning machine is provided. The floor cleaning machine includes a solution tank for a cleaning solution. A pre-canister sensor receives the cleaning solution and measures the concentration of any dissolved solids. A canister assembly receives a portion of the cleaning solution from the pre-canister sensor and dissolves portions of a solid chemical form into the cleaning solution thereby forming blended droplets. The canister assembly has a spray nozzle positioned vertically above the solid chemical form. A post-canister sensor receives a mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. The post-canister sensor measures the concentration of any dissolved solids within the mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. A comparison of the baseline and post-canister measurements outside of a desired range results in replacement of the solid chemical form.

A system for mineralizing distilled water includes a splitter for splitting distilled water into primary and secondary portions; first and second conduits for conveying the primary and second portions, respectively; first and second columns comprising including first and second mineral matrices connected to the first and second conduits, respectively, to generate first and second mineralizing concentrate solutions; first and second mixing modules for combining a predefined amount of the mineralizing concentrate solutions with the primary portion of distilled water to form a mineralized water mixture; and a dispensing module for dispensing the mineralizing water mixture. A carbonator is also connected to the secondary conduit for dissolving carbon dioxide in the secondary portion of distilled water upstream of the first and second columns.

A device is provided for preparing a chemical solution. The device comprises a dissolving bowl having an open top portion for receiving a solid chemical material and a closed bottom portion. A grid member is disposed between the top and bottom portions for supporting the chemical material on a top surface thereof defining an array of grid openings and a flow opening distinct therefrom. A nozzle is positioned proximate the bottom portion and directs flow of an aqueous fluid to contact and dissolve at least some of the chemical material and create a chemical solution thereof n insert disposed proximate the grid member impedes flow of the aqueous fluid through one or more of the grid openings to increase fluid turbulence within the dissolving bowl and/or redirects the fluid flowing from the flow opening to flow in one or more directions over the grid member.

A multi-reservoir feeding/dosing apparatus for the delivery of at least two substances in discrete form includes first and second conveying elements in which the discharge end thereof are a close fit in a discharge bushing thereby to ensure that the correct dosage of each substance is discharged on a consistent basis. Each conveying element is in its respective reservoir. At least one motor drives both conveying elements, with each rotational direction of the motor actuating a corresponding one of the conveying elements.

A method of providing a salt solution at a wellbore site includes delivering solid salt in a mixing tank containing water from a local source and pumping the water through nozzles in the mixing tank using a pump adjacent to the mixing tank to circulate the water in the mixing tank and form a concentrated brine by dissolving the solid salt in the water. The concentrated brine is transferred from the mixing tank to a reservoir using the pump, and the concentrated brine is diluted with additional water from the local source to form a dilute brine. A related mixing tank and a system including the mixing tank and a vehicle structured and configured for travel over a roadway and within an oilfield site.
