“…The utilization of NTP equals a combination of ozone and other ROS, which seems to be overproportionally better than ozone alone. This 'enhancer' effect has already been reported in a previous study concerning the removal of organic micropollutants in wastewater via NTP [21].…”

Arsenic in drinking water resources and, especially, in groundwater, represents a severe health problem for millions of people in affected regions. This paper investigates a removal technology combining non-thermal plasma at a reaction time of 30 min, which has improved the downstream coagulation and the filtration efficiency. The results show removal rates of total arsenic over 98%. In addition, WHO limits of less than 10 g / L could be achieved in both batch and continuous set-ups. A difference in effective over potential of the NTP reaction of 32 m V over a reaction using air as oxidant was calculated. Kinetic data of arsenic concentrations over time fitted a pseudo first-order reaction. The proposed process combination has shown to be a simple and energy-saving alternative compared to conventional oxidation and adsorption technologies by exploiting the ’enhancer’ effect of ozone and other reactive oxygen species within the NTP.

“…Treatment using ultrafiltration or NTAPP eliminated these pharmaceuticals pollutants to a greater degree, although the percentage removed did not exceed 90%. This study suggested that the use of NTAPP technology with ultrafiltration is a feasible and energy-efficient treatment approach for large-scale wastewater treatment [125]. Treatment approaches by using different NTAAP sources to remove the different chemical pollutants are summarized in Table 2.…”

Various reactive oxygen and nitrogen species are accompanied by electrons, ultra-violet (UV) radiation, ions, photons, and electric fields in non-thermal atmospheric pressure plasma. Plasma technology is already used in diverse fields, such as biomedicine, dentistry, agriculture, ozone generation, chemical synthesis, surface treatment, and coating. Non-thermal atmospheric pressure plasma is also considered a promising technology in environmental pollution control. The degradation of organic and inorganic pollutants will be massively advanced by plasma-generated reactive species. Various investigations on the use of non-thermal atmospheric pressure plasma technology for organic wastewater purification have already been performed, and advancements are continuing to be made in this area. This work provides a critical review of the ongoing improvements related to the use of non-thermal plasma in wastewater control and outlines the operational principle, standards, parameters, and boundaries with a special focus on the degradation of organic compounds in wastewater treatment.

“…The energetic electrons effectively induce excitation, dissociation and ionization of the gas discharge medium, yielding amongst others nitrogen and oxygen-based excited states, radical species and ions. Primarily produced reactive nitrogen (RNS) and reactive oxygen species (ROS) will react with pathogens and organic molecules by disinfecting and degrading pollutants in wastewater (Shen et al, 2016;Gerrity et al, 2010;Back et al, 2018;Thirumdas et al, 2018). It is demonstrated that AOPs including plasma oxidation are promising techniques for on-site wastewater treatment prior to conventional WWTP (Ajo et al, 2018;Graumans et al, 2021).…”

“…Next to that, in presence of bromide, the AOP ozonation (O 3 ) can generate bromated toxic by-products (Wu et al, 2019;Yang et al, 2019). Additional filtration steps with activated carbon are needed for the removal of these toxic intermediates formed by oxidation (Heringa et al, 2011;Back et al, 2018). To circumvent and minimize the formation of oxidative by-products, it is suggested to apply AOPs early in the wastewater chain.…”
