Controlled dosing of chlorine dioxide or other sanitizing agents into pressurized water systems

Abstract

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.

1 . A system for delivering controlled doses of a sanitizing agent to a fluid, comprising: 
 a disposable substantially hollow pressure vessel having 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;    one or more reactants operatively disposed in the chamber which form a sanitizing solution upon contact with the fluid as it enters the chamber, wherein further mixing of the fluid and the solution occurs within the chamber prior to egress through the outlet passage.    
     
     
         2 . The system of  claim 1 , wherein the reactants form a solution of chlorine dioxide in water.  
     
     
         3 . The system of  claim 1 , wherein the system provides the sanitizing solution to equipment lines or pipes.  
     
     
         4 . The system of  claim 1 , wherein the disposable substantially hollow pressure vessel is replaced after each sanitizing operation.  
     
     
         5 . A The system of  claim 1 , wherein the disposable substantially hollow pressure vessel also contains filtration media.  
     
     
         6 . The system of  claim 1 , wherein the sanitizing solution also has a dye indicator for facilitating awareness of the presence of the sanitizing agent in the fluid and the subsequent exhaustion thereof from the fluid.
