A method of aerating a powdered chemical composition comprising: (a) supplying a fluid flow to a container having a powdered chemical composition therein, the fluid flow being supplied by a fluid supply device; (b) aerating at least a portion of the powdered chemical composition by selectively introducing the fluid flow into the powdered chemical composition within the container; (c) routing the fluid flow from the container back to the fluid supply device after being introduced into the powdered chemical composition; and (d) recirculating the fluid flow through the powdered chemical composition within the container and through the fluid supply device in a closed loop path by performing steps (a)-(c), as desired, wherein the fluid flow is not utilized for transporting the powdered chemical composition from an aeration system comprising the container and the closed loop path.
