A brine maker including a hopper having an open upper end and an open lower end with the hopper being configured to receive salt therein. A solids screen is positioned at the lower end of the hopper. A receiving tank having an open upper end is positioned below the solids screen. An overflow tube is positioned in the hopper and has an upper end positioned below the upper end of the hopper. When the level of salt brine reaches the upper end of the overflow tube, the salt brine will overflow into the overflow tube and will pass downward therethrough the solids screen and into the receiving tank. The invention includes a second embodiment wherein an overflow panel with an upper end is positioned in the hopper thereby creating a passageway into which brine overflow may pass thereinto and pass through the solids screen into the receiving tank.

A brine maker including a hopper having upper and lower ends with a receiving tank positioned below the hopper. The forward end of the receiving tank has an opening formed therein. An elbow fitting is positioned in the opening in the forward end of the receiving tank and is welded to the forward end of the receiving tank. The elbow fitting includes a vertically disposed hollow upper portion which is positioned in the receiving tank and a horizontally disposed hollow lower portion which is positioned in the opening in the forward end of the receiving tank. The horizontally disposed hollow lower portion of the elbow fitting is fluidly connected to a pump. A shield is secured to the inner side of the forward end of the receiving tank above the upper end of the vertically disposed hollow upper portion of the elbow fitting.

A method and apparatus for obtaining a product chemistry from a slid block of caustic material is provided. The product is housed within a capsule which is positioned inside a turbulent flow dispenser, which utilizes fluid to erode the block and produce a concentrated solution. The fluid characteristics can be adjusted in the field to achieve a predetermined concentrate level of the solution. The capsule provides a safe and convenient means for handling, storing and shipping the caustic block without exposing the operator or handler to the hazardous material. The capsule includes nested components which can be rotated between a closed or sealed position and an open use position.

A method for obtaining a chemical concentration from a chemical composition and a fluid includes introducing the fluid through ports in a manifold diffuse member positioned adjacent a chemical composition and adjusting, with a fluid valve, characteristics of the flow of the fluid through the ports in the diffuser manifold to obtain and maintain a chemical concentration. The amount of liquid allowed through the ports modifies the turbulence of the liquid, thereby modifying the erosion rate of the chemical composition. An apparatus for adjusting characteristics of the flow of a fluid contacting a solid product to form a product chemistry includes a diffuser manifold having a manifold diffuse member comprising ports therethrough and a fluid valve for controlling the flow rate of a fluid moving through the plurality of ports and diverting the fluid through various flow paths.

A brine maker including a hopper having an open upper end and an open lower end with the hopper being configured to receive salt therein. A solids screen is positioned at the lower end of the hopper. A receiving tank having an open upper end is positioned below the solids screen. An overflow tube is positioned in the hopper and has an upper end positioned below the upper end of the hopper. When the level of salt brine reaches the upper end of the overflow tube, the salt brine will overflow into the overflow tube and will pass downward therethrough the solids screen and into the receiving tank. The invention includes a second embodiment wherein an overflow panel with an upper end is positioned in the hopper thereby creating a passageway into which brine overflow may pass thereinto and pass through the solids screen into the receiving tank.

A method of reconstituting a powdered cell culture media includes providing a mixing apparatus and providing a powdered cell culture media to the fluid chamber of the mixing apparatus, prior to introducing fluid to the chamber. The method further includes introducing fluid to the chamber through an influent port, wherein the influent port is tangentially oriented relative to an inner wall of the fluid chamber to thereby cause the fluid to follow the wall of the fluid chamber in a circular motion, creating a vortex flow in the fluid chamber by introducing fluid at a sufficient flow rate, and enhancing the vortex flow with a geometric fluid flow aid by further channeling the water around the wall of the fluid chamber, around the geometric flow aid. The method further includes continuing to introduce fluid to the chamber and collecting reconstituted fluid that exits the chamber through the effluent port.

A portable dispensing system for dispensing a solution of a fluid and a solid product includes a fluid line, a dispenser, and a cartridge. The fluid line includes a first and second fluid line ends and a fluid source connection at the first fluid line end. The dispenser is at the second fluid line end. The dispenser includes a body and a fluid outlet. The cartridge houses the solid product and includes a fluid inlet and a solution outlet. The cartridge is removably connected at the fluid inlet to the fluid outlet of the dispenser. The cartridge is configured to receive fluid from the fluid outlet of the dispenser such that fluid contacts the solid product housed in the cartridge and dissolves at least a portion of the solid product forming the solution. The cartridge is also configured to output the solution at the solution outlet.

A system for dissolving solid chemical may include three reservoirs positioned in a vertically stacked arrangement. A solid chemical reservoir configured to receive solid chemical to be dissolved may be nested in a solution generator reservoir into which water is introduced to erode the solid chemical. A dissolved chemical reservoir can be positioned under the solid chemical reservoir and the solution generator reservoir. The dissolved chemical reservoir can store solution generated using the system. In some examples, a recirculation circuit is used to recirculate water introduced into the solution generator reservoir until a solution having a target concentration of the chemical being dissolved is achieved. The recirculation circuit may include a recirculation line having an outlet aimed at the bottom wall of the solid chemical reservoir.

A production device includes: at least one device for dissolving solid urea in demineralized water, including a tank for receiving the solid urea and the demineralized water and an outlet for recovering the aqueous solution of urea; a solid urea storage station; and a device for transporting the solid urea from the storage station to the dissolving device, the transporting device being arranged in order to pour solid urea into the tank of the dissolving device. The dissolving device includes at least one nozzle for injecting demineralized water into the solid urea, arranged in the vicinity of the bottom of the tank in order to create water turbulence below the surface of the solid urea and to dissolve the solid urea in the demineralized water.
