Patent ID: 7833392

Claim:
A chlorine dioxide solution generator comprising: (a) a chlorine dioxide gas source comprising a packed stripper column under vacuum capable of producing a substantially pure chlorine dioxide gas stream by vacuum; (b) an eductor system for at least partially effecting the dissolution of said substantially pure chlorine dioxide gas stream into an aqueous liquid stream wherein said eductor system comprises one inlet fluidly connected to said chlorine dioxide gas source, said substantially pure chlorine dioxide gas stream exiting said packed stripper column directed to said eductor system via said inlet fluidly connected to said chlorine dioxide gas source, a second inlet for receiving an aqueous liquid fluidly connected to a recirculation pump and an outlet wherein pumping of said aqueous liquid creates a vacuum in said packed stripper column; and (c) an absorption system fluidly connected to said eductor system via said outlet that is capable of effecting additional dissolution of said chlorine dioxide gas into said aqueous liquid wherein said absorption system is fluidly connected to a dosing pump capable of delivering a chlorine dioxide solution from said absorption system into a pressurized water system.
