Devices and systems for preparing a chemical solution

A system for preparing a chemical solution comprising:

• a chemical feeder comprising:
• a dissolving bowl comprising an open top portion for receiving a solid chemical material therethrough and a closed bottom portion;
• a grid member disposed within the dissolving bowl between the top portion and the bottom portion, the grid member arranged for supporting the solid chemical material on a top surface thereof, the grid member defining an array of grid openings and a flow opening distinct from the grid openings;
• a nozzle disposed within the dissolving bowl and positioned proximate the bottom portion, the nozzle arranged to direct flow of an aqueous fluid into the dissolving bowl from the bottom portion towards the grid member to thereby cause the aqueous fluid to contact and dissolve the solid chemical material and create the chemical solution of the aqueous fluid and the solid chemical material dissolved therein, wherein the grid openings allow the chemical solution to flow therethrough toward the bottom portion of the dissolving bowl, wherein the nozzle is directed toward the flow opening of the grid member to provide fluid flow from the nozzle toward the flow opening of the grid member;
• and
• an insert disposed within the dissolving bowl and proximate the grid member, the insert arranged to impede flow of the aqueous fluid through one or more of the grid openings sufficient to increase fluid turbulence within the dissolving bowl and/or redirect the fluid flowing from the flow opening to flow in one or more directions over the top surface of the grid member.
