1. An apparatus for the controlled release of an active agent into an aqueous system, the apparatus comprising:
at least one active agent portion, said active agent portion comprising a body, said body defining a first side, a second side, and a third side; a container, said container comprising a first polymeric layer spaced apart from a second polymeric layer, said first polymeric layer comprising a first inside surface, said second polymeric layer comprising a second inside surface, said active agent portion retained within said container, said active agent portion held between said first and second polymeric layers with said first inside surface contacting said first side of said active agent portion and said second inside surface contacting said second side of said active agent portion, said container defining a reservoir adjacent said third side; an inlet opening defined in the container, said inlet opening extending through the container and into the reservoir, said inlet opening configured for fluid connection with a fluid source, thereby enabling a supply of fluid to flow into the reservoir from the fluid source to dissolve a portion of said active agent from said third side of said active agent portion thereby creating a solution, wherein said supply of fluid dissolves said portion of said active agent from said third side before dissolving said first or second sides; and an outlet opening defined in the container, said outlet opening extending through the container and into the reservoir, said outlet opening configured for allowing the solution to flow out of the reservoir and into said aqueous system. |
