Integrated Ozone Microreactor Technology for Water Treatment

Abstract

Safe and clean potable water is a basic primary need for daily living and the ability to process water using minimal expenditure of resources provides tremendous advantages. In this work, we present ozone process technology being developed at KWJ Engineering to decontaminate recovered potable water and greywater with a small energy footprint. The technology involves the in-situ generation of ozone, a powerful broad spectrum disinfectant, generated from air. Unique microreactor technology integrated with a low power ozone source enables high efficiency mixing of water and ozone at high mass transfer rates for decontaminating a multitude of pathogens and chemical contaminants. The compactness and low power feature of microreactors and micro-ozone generators creates a portable and scalable system that can provide on the spot potable water in many situations such as disaster relief, rural communities and space habitats.
