 Water droplets can be used to effectively kill bacteria, such as escharicicoli and salmonella tifemurium, without producing harmful byproducts or requiring high temperatures. This method is more cost-effective and efficient than traditional disinfection methods, such as using chemicals or heat. The droplets are created when pure bulk water is sprayed through a nozzle with coaxial nebulizing airflow, resulting in a 98% reduction in bacteria. This article was authored by Maria T. Jule, J. Q.
