Abstract: An aeration system for circulating an aerating fluid through a chemical composition within a container. The aeration system is closed-loop such that the aeration fluid is supplied by a fluid supply system to the interior of a container to aerate the chemical composition therein. The aeration fluid is returned to the fluid supply system for subsequent redelivery to the container. A filtering mechanism may be employed to remove large particulate matter from the aeration fluid prior to flowing back to the fluid supply system. The aeration process improves the flowability of the chemical composition thus facilitating the transferring and/or discharging of the chemical composition from the container. The aeration process may occur during transport, prior to discharging, and/or during a discharging or transferring operation.
