Problems solved by technology

While such techniques reduce the amount of fine powder, they are generally ineffective at preventing the components of the solid matter from reacting with water vapor
Further, lumps / flakes are not ideal when routinely treating large volumes of water with large volumes of material

Abstract

The creation of chlorine dioxide in a water system can be accomplished by an improved mixture of components that includes a chlorite salt, oxidizing chlorine releasing agent(s) and an acid source and these improved combinations of materials can be pre-measured and delivered into a water system in sealed water soluble containers.

Description

Background technique [0001] The present invention relates to a solid composition which, when dissolved in an aqueous solution, generates and releases chlorine dioxide (ClO 2 ), compared with currently known compositions in the art, the temperature stability of the composition is improved, and the present invention also relates to a method of transporting solid chlorine dioxide compositions. [0002] Chlorine dioxide has long been known to be a highly effective antimicrobial, viricide, bactericide, fungicide, algaecide and / or sporicide. Its potency and the absence of a halogenation (or chlorination) reaction make it particularly desirable. However, gaseous chlorine dioxide has limited commercial applications due to storage and transportation difficulties. [0003] At present, various combinations of solid raw materials have been developed. When these solids are dissolved in aqueous solution, chlorine dioxide can be produced to varying degrees. The above combination includes ...
