Abstract:
1. A method for releasing additives into a fluid comprising the steps of (1) operating a device that utilizes a fluid, wherein the device further utilizes a delivery system for supplying one or more additives to a fluid wherein said delivery systems comprises an additive gel, a filter comprising a housing, and a fluid/gel chemistry exchange region, wherein the filter housing comprises a region that experiences a direct flow of the fluid as it passes through the filter housing, wherein the fluid/gel chemistry exchange region is located outside of the region of the filter housing that experiences the direct flow of the fluid where fluid passing through the filter housing will contact the gel in the fluid/gel chemistry exchange region; and (2) passing the fluid from the fluid-utilizing device into the filter housing and then passing the fluid into the fluid/gel chemistry exchange region of the filter housing where said fluid comes into contact with the additive gel, resulting in the release of additives from the gel to the fluid; and (3) returning said fluid to the fluid-utilizing device; and wherein the filter housing comprises a body and a cap, where the cap comprises an inner wall and an outer wall, wherein the inner wall forms a cylinder within the cap that connects to the outer wall at one end of the cap and is separate from the outer wall at the other end such that said cylinder is open at the other end of the cap of the cap; and wherein the inner wall and outer wall form an annular space along the outer wall of the cap and wherein the additive gel is placed within the annular space; wherein the cap fastens to the body of the filter housing forming the filter housing such that the cap is located on the filter housing at an opposite end of the filter housing that mounts onto said fluid-utilizing device; and wherein said fluid/gel chemistry exchange region is located within said cap.
