###### Abstract
New methods of water treatment by plasma must have all the above-mentioned properties and pose the least risk to public health. NTAPPs and their chemical reactions release energy and reactive chemical species that can kill bacteria and microorganisms, resulting in the disinfection of water. The advantage of this technique is that it can be performed in ambient air under atmospheric pressure without a vacuum system. Furthermore, NTAPP does not involve chemical products such as Cl [20]. NTAPP can be used for water treatment in three ways: via direct, indirect, and bubbling methods. In the direct method, the water/target is kept between the two electrodes and the plasma is exposed to the water directly. This type of plasma-water treatment includes streamer and spark approaches [45; 46]. In the indirect method, both electrodes lie above the target/water, plasma is produced above the water, and the reactive species from the plasma diffuse into the water, meaning that there is a contact surface. When the plasma is directly exposed to the water, electrons and reactive O species (ROS) are transported to the plasma-water interface and ultimately solvated into the bulk volume [34; 45]. In the bubbling method, plasma is produced inside bubbles and injected into the water. In this case, ROS are transported by bubbles. The generation of plasma inside the bubbles and monodispersing in water can increase the plasma-liquid contact surface area considerably [47; 48]. [PERSON] et al. [47] showed that the efficiency of certain plasma reactor geometries for inducing the interaction of plasma with thin layers of water or water aerosol is likely due to significant ROS loading into these thin layers. The following parameters determine water quality and enable water to be labeled as drinkable: the concentration of Ca ions (which should be between 50 and 60 mg/L), concentration of H\({}_{2}\)CO\({}_{3}\) or alkalinity, concentration of Mg ions (where 36 mg/L is the maximum acceptable value), and concentration of CaCO\({}_{3}\) or precipitation index (where a low amount is required) [49]. The conductivity; concentrations of Al, Mn, Fe, Mb, sulfate, phosphate, Zn, Cl, and biological organisms such as _Escherichia coli_; total coliforms; natural colors; turbidity; and permanganate number are other important parameters that should be analyzed and limited during disinfection [49; 50]. There are also some factors that influence water disinfection, such as the contact time, microorganism type, microorganism age, water that requires treatment, and temperature. To increase knowledge about wastewater management systems, this article shows the possibility of using NTAPP for purification, bio-sterilization, and decontamination in wastewater treatment on a large scale. Figure 1 depicts the recent progress in disinfection and sterilization using NTAPP. As plasma devices are simple and efficient and do not require the addition of chemical agents to decompose toxic organic compounds, an increasing amount of research is being conducted on the use of plasma to disintegrate these wastes in water. Various reactor types with different energy efficiencies have been used in research. For instance, [PERSON] et al. [52] investigated and compared the relative energy yields of around 27 notable kinds of plasma devices. They demonstrated that considerable differences in energy efficiency exist, up to five orders of magnitude. The most effective approach involved pulsed plasma created in gas media. This investigation will facilitate the design of efficient reactors for additional examinations, development, and commercial use. In addition to an appropriate plasma design, suitable working conditions can affect the complete decomposition of pollutants. [PERSON] et al. [53] indicated that tuning the appropriate operating conditions is essential to achieve pollutant degradation and avoid the formation and consequent accumulation of reaction intermediates in the treated water.
