Plasma Physics for High Throughput Water Reuse

Abstract

In response to water scarcity, water reuse initiatives demand advanced treatment techniques. Water technology must be effective, environmentally friendly, cost efficient and versatile. Advanced oxidation processes (AOPs) are established effective disinfection methods, particularly for the removal of contaminants of emerging concern (CECs). On the other hand, conventional AOPs are expensive due to higher capital, operational and maintenance costs from required consumables and associated infrastructure. Plasma injection in liquid water can also generate AOPs in solution while eliminating consumables and conversion efficiencies. Thus, in principle, plasma-based AOPs should be considerably cheaper and more effective than conventional AOPs.
