Title: CHLORINE DIOXIDE GENERATION
Abstract:
Devices and methods for safely using acid/chlorite ClO2 generator chemistry for water treatment, whereby a valve prevents chemical draw unless there is both vacuum within the reaction chamber as well as suitable water volume in the flow chamber for dilution, are described. The float-dependent valve can also allow for direct venting from the reaction chamber to the flow chamber in the event of elevated pressure in the reaction chamber. This approach delivers an inherently safer ClO2 generator design for systems that utilize high strength reactor zones with ClO2 concentration above 3,000 ppm.
