Provided herein are systems, apparatuses, and methods for localized, on-demand diesel exhaust fluid (“DEF”) production. The systems can comprise a loading station for securing a container comprising a pre-measured quantity of urea and releasing the urea from the container. The released urea and water can then be fed into a mixing tank to produce the DEF product. The water can be pre-treated, for example, in a reverse osmosis and/or deionization process before being fed to the mixing tank. The DEF product can be immediately dispensed into a diesel vehicle or stored in a nearby intermediate storage tank. The systems and processes advantageously reduce or eliminate the need for over-the-road shipments and retail packaging of DEF.

The fluoride tablet feeder device is a device for dissolution of fluoride tablets into a water stream. The device is specifically designed for the fluoride tablets disclosed and claimed by U.S. Pat. No. 10,485,738 titled Tablet for Fluoridating Potable Water, which is incorporated by reference. The crux of ideal dissolution of fluoride tablets in a flowing water supply is total immersion of the tablets, with water flowing around all tablet sides for even dissolution.

A system for mixing a liquid with a powder into a solution batch includes a hopper (20) into which said powder is deposited, the hopper (20) having a powder outlet (22) therein. A mix tank (60) is also provided having a liquid supply inlet (62), a recirculation inlet (64), and a solution outlet (66). A mix pump (40) that is in fluid communication with the solution outlet (66), the powder outlet (22), and the recirculation inlet (64) operates to mix and transfer the solution.

The present disclosure provides a fracturing fluid mixing equipment including a clear water supply system, at least two mixing systems, at least one powder tank, at least two powder conveying systems, a mixing tank, a feeding system and a power system. The clear water supply system has two parallel water supply paths which are connected to the mixing system and the mixing tank respectively. The powder conveying system is connected to the powder tank. There are same number of powder conveying systems and mixing systems which are connected in one-to-one correspondence. The mixing system is connected into the mixing tank. The feeding system adds powder by pneumatic conveying. The power system provides driving force by pure electric power and/or electro-hydraulic power. According to present disclosure, the power system can reduce fuel consumption and exhaust emissions. The feeding system can be compatible with various adding conditions of powders in different packaging, which can reduce the possibility of dust pollution, thereby reducing labor costs and occupational injuries and being more efficient and environmentally friendly.

The methods and systems of the invention include the use of automated solution dispensers in laboratory environment. The automated solution dispensers can be controlled locally or remotely within a network. The usage of the instruments can be followed and procurement of supplies can be automated.

An automated method includes providing a dry ingredient to be reconstituted into a liquid bioprocess solution and controlling, by a processing circuit, all automated system including at least one mixing chamber, an array of tubing for fluid flow within the system, and a plurality of valves provided within the tubing, to automatically prepare the liquid bioprocess solution from the dry ingredient. Controlling the auto system may include performing a series of sequential mixing steps, the series of sequential mixing steps causing the preparation of the liquid bioprocess solution. The method mixing include taking one or more measurements during the preparation of the liquid bioprocess solution, wherein each step is triggered by at least one of a measurement decreasing below, equaling, or exceeding a measurement threshold. Each step may also include opening or closing, by the processing circuit, at least one of the plurality of valves.

Disclosed is a dissolution mixer, which includes: a dissolution bath configured to accommodate a powder and a solvent for dissolving the powder; a powder input unit located at an outer side of the dissolution bath; an impeller installed to be rotatable inside the dissolution bath; and an anchor located inside the dissolution bath and having a passage of the powder inputted by the powder input unit and a powder spouting hole connected to the passage.

A brine machine comprises a salt hopper, a source of water for wetting salt in the salt hopper, a brine hopper positioned in side-by-side relation relative to the salt hopper, a filter providing fluid communication between the salt hopper and the brine hopper, a generally horizontal auger positioned in a base of the salt hopper, and an upwardly directed lift auger having a first end in operable association with an end of the horizontal auger and a second discharge end positioned above a level of brine in the brine hopper. The augers convey solid material from the base of the salt hopper and discharge the material from the machine.

A system and method for mixing and dispensing one or more pesticides includes a plurality of pesticide containers (5) for containing pesticide and at least one dosing device (7) associated with the pesticides containers and adapted to dose pesticide from the pesticide containers. A mixing device (9) receives pesticide from the dosing device and mixes the pesticide to form at least one of a pesticide solution and a pesticide mixture. A computer device (21) includes a processor and is adapted to receive an input from a user and based on that input operate the dosing device to dose a quantity of pesticide from one or more of the pesticide containers.
