Publication number: 20200346175Abstract: The invention is an apparatus for preparing a chemical solution. A device of the present invention includes a housing including a lower chamber and an upper chamber and a dissolving bowl arranged at an interface of the lower chamber and upper chamber. The dissolving bowl includes a grid disposed within. Solid, undissolved chemical material rests on a top surface of the grid, such that the grid is able to maintain physical separation of the solid, undissolved chemical material from at least a bottom portion of the dissolving bowl. The device further includes a nozzle disposed within the dissolving bowl and positioned so as to direct flow of aqueous fluid into the dissolving bowl and towards the grid. The dissolving bowl further includes an outlet in fluid communication with the lower chamber to thereby allow for a prepared chemical solution to flow from the dissolving bowl into the lower chamber.Type: ApplicationFiled: May 1, 2020Publication date: November 5, 2020Inventors: David W. Blanchette, Matthew Muller
