Abstract
The present disclosure relates to a defoaming substance for defoaming an aqueous solution. The defoaming substance includes a defoaming agent and a carrier material intermixed with the defoaming agent to form a solid mass, the carrier material being at least minimally soluble in the aqueous solution. In one embodiment, the carrier material includes at least one type of organic acid. The defoaming agent may include at least one type of silicon-based defoamer. The present disclosure also relates to a method for making a defoaming substance. The method may include selecting a defoaming agent capable of hindering foam formation and reducing foam build-up in an aqueous solution, selecting a carrier material that is at least minimally soluble in the aqueous solution, combining the defoaming agent with the carrier material, and forming the combined defoaming agent and carrier material into a solid defoaming substance.
