In various respects, the invention is directed to an insulated system that reduces heat loss from catalyzed neutralization of a disinfecting solution resulting in an increased temperature of the disinfection solution during the disinfection process and neutralization of the disinfection solution.

Increase of the kill rate allows better reduction of microorganisms resistant to elimination using previous systems and methods, (e.g., Acanthamoeba cysts), and decreases the amount of time as compared to previous systems and methods necessary to reduce microorganisms to acceptable levels.
