Ozone Makes A Comeback

Ozone has been a proven effective method of water treatment and disinfection for well over a century. Despite its effectiveness, ozone has seen limited adoption, especially in the US, due to its perceived cost and complexity. Today, a growing interest in the removal of trace contaminants such as pharmaceuticals, personal care products (PCPs) and other so-called endocrine disrupting compounds (EDCs) have renewed interest in ozone as a treatment option at an increasing number of water and wastewater treatment plants. The goal of this article is to provide a brief overview of the methods and types of compounds and applications best treated using ozone.
