Disinfection systems come in a wide variety of shapes and processes, and the benefits of each are thorough and safe microbiological protection. These options include chlorine dioxide systems, electrolysis systems, ozone systems, and UV systems. UV systems work entirely without chemicals, as UV radiation alone produces microbiologically safe water with no harmful disinfection by-products. Ozone is the strongest oxidant and disinfectant currently used in water treatment, and it is extremely effective against bacteria and viruses.
