Abstract

Graphical abstract: Highlights: NTP is an effective approach for water decontamination applications. The technology has huge research interest and commercial potential. Combining NTP with other techniques can provide synergistic benefits. In-depth studies are needed to explain exact mechanisms of action. Future research must be focused on technology scale-up. Abstract: Water treatment techniques are an integral aspect of a range of applications covering agriculture, environment, health, and their interfaces. In recent years, among the numerous approaches involved, non-thermal plasma (NTP) treatment has gained enormous research interest for the removal of the contaminants in water. This process is an effective route for increasing the biodegradability of recalcitrant pollutants. The focus of this review is to detail the underlying chemical and physical effects that are responsible for the decontamination of microbial and chemical (organics and pharmaceuticals) species in water. The mechanisms behind other interesting applications such as the use of NTP for surface modification of membranes used for water treatment applications are also highlighted. All these are explained with the range of reactor design variants and the effect of process and operating variables on decontamination efficiencies. The economic feasibility of NTP technology towards decontamination has been discussed. Promising applications involving the use of plasma treatment in combination with adsorbents, catalysts, electrolysis, biodegradation, ultrasonication, ozonization, and ultrafiltration processes are explained. A summary of recent studies on such topics is presented, emphasizing the challenges and directions for future research.
