Abstract
Various methods and systems are provided below for the treatment of wastewater. According to various embodiments, treatment of wastewater is accomplished using the oxidative power of ozone gas and the interaction between ozone gas, FOGS, and large amounts of surfactants already present in wastewaters to be treated. According to various embodiments of the invention, a combination of oxidation and UV disinfection is used to provide a fact acting treatment for wastewater. These methods and systems generally enable reduced footprint in relation to the volumes treated, reduced cost, and increased efficiency. Various alternative embodiments are also disclosed.
