Photos: Novazone's pest killer

Compressors and storage tanks for Novazone's ozone disinfectant system. The company's equipment sucks in air, separates out the oxygen, and then makes ozone--a molecule made up of three oxygen atoms--from it. The ozone is then sprayed into water or fruit. It kills microbes, and the residue turns into regular oxygen.
