A medium having a support structure configured for circulation of a fluid therein, such as a replaceable filter cartridge, including a sanitizing agent which contains one or more reactants that are chemically configured for delivering chlorine dioxide or other sanitizing agents in a controlled dose to sanitize, deodorize, and disinfect upon being wetted by the fluid and positioned in the medium support structure to be exposed to the fluid circulating therein. |

DETAILED DESCRIPTION The present invention provides new and useful systems and methods for delivering controlled doses of chlorine dioxide or other sanitizing agents into a pressurized potable water system which overcomes the problems associated with the prior art.
A medium having a support structure with an inlet configured for receiving a fluid, an outlet configured for delivering a fluid and a body configured for circulating a fluid therein, such as a replaceable filter cartridge, which includes a sanitizing agent containing one or more reactants that are chemically configured for releasing a compound having sanitizing properties, such as chlorine dioxide, in a controlled dose upon being wetted by the fluid and positioned within the medium to be exposed to the fluid circulating therein.
Preferably, the sanitizing agent releases chlorine dioxide or other sanitizing agents in specific amounts, at a specific and controlled constant rate, to sanitize, deodorize, and disinfect equipment pipes connected to the medium outlet.
The rate of chlorine dioxide or other sanitizing agents release would be set to dilute in water with a constant flow rate for a duration equivalent to perform the desired task, such as sanitize, deodorize, or disinfect water lines and equipment wetted parts.
The preferred mediums to be used in accordance with the present invention include systems or disposable cartridges.
In particular, the present invention, is directed to a system for delivering a sanitizing agent to a fluid, which includes a substantially hollow vessel and a sanitizing agent having one or more reactants which are chemically configured to release a compound having sanitizing properties upon exposure to the fluid.
The hollow vessel includes an inlet passage configured for receiving fluid flow, an outlet passage configured for fluid egress, and an interior chamber configured for receiving fluid from the inlet passage and providing temporary confinement of the fluid therein prior to egress from the outlet passage
