Abstract:
1. A method for generating chlorine dioxide, comprising the steps of: 1) moving a casing relative to a venturi body to change the size of a plenum in order to generate a predetermined amount of chlorine dioxide, said plenum being defined between said casing and a venturi and sealed therebetween, said venturi having an inlet end and an outlet end, said outlet end being attached to said venturi body; 2) feeding fluid into said inlet end of said venturi; 3) feeding chlorine dioxide generating reactants into a plenum entry ring through a feed port, said feed port extending through a collar, said plenum entry ring being defined between said casing and said collar and sealed therebetween, said collar being located at said inlet end of said venturi; and wherein said reactants mix together in said plenum and react to form chlorine dioxide which exits through an injection port located at said outlet end of said venturi, thereby joining said fluid at the outlet end of said venturi.
