“…Figure 3(c) shows the gliding arc discharge of non-thermal plasma which is widely used for wastewater remediation purposes. As compared to other types of discharges, it offers high operating pressure, power and plasma density (Krishna et al 2016). Moreover, GAD possesses the characteristics of both thermal and non-thermal plasma.…”

“…Similarly, Krishna et al (2016) studied the efficacy of gliding arc plasma discharge system for degradation of verapamil hydrochloride in water. The results revealed that initially, concentration of verapamil in water was 5×10 -5 M and 5×10 -4 M. However, after treating for about 80mins there was a significant reduction in initial concentrations by 97 % and 37 %, respectively.…”

Cold plasma has been a potent energy-efficient and eco-friendly advanced oxidation technology which has gained attention in recent decades as a non-thermal approach in diverse forms of applications. This review highlights a comprehensive account of the implementation of this technology in the field of wastewater treatment to resolve certain issues regarding the degradation of numerous aqueous pollutants and water-borne pathogenic microorganisms including viruses up to a significant level. The paper addresses plasma chemistry sources and mechanisms on wastewater treatment and impact on various physical, chemical, and biological characteristics of treated water. Furthermore, studies have revealed that this emerging technology is effective in inactivating SARS-CoV-2 or coronavirus, which serves as a transmission channel for this lethal virus in wastewater. Despite these benefits, the development of cold plasma as a wastewater treatment technique is still hampered by a lack of information like capital investment, proficient application, liveability, and operating cost, thus necessitating additional research for its booming commercialization, as this can be an emerging approach to solving water crises and meeting the demand for fresh or potable water resources.

“…However, traditional wastewater treatment plants are not designed for the reduction of certain pharmaceuticals [123]. Therefore, cold plasma-based advanced oxidation processes have been investigated extensively to remove various non-biodegradable pharmaceutical compounds [10,96,124].…”

“…The degradation of telmisartan was observed as pseudofirst-order kinetics with applied voltage. Krishna et al [124] evaluated the removal of Verapamil hydrochloride from water under the action of gliding arc plasma in air where the discharge was created between two divergent electrodes above the solution. The first-order degradation was obtained and a higher removal rate constant was noticed when the initial concentration of the target compound was lower.…”

Cold atmospheric plasma technology for removal of organic micropollutants from wastewater—a review

et al. 2021

Water bodies are being contaminated daily due to industrial, agricultural and domestic effluents. In the last decades, harmful organic micropollutants (OMPs) have been detected in surface and groundwater at low concentrations due to the discharge of untreated effluent in natural water bodies. As a consequence, aquatic life and public health are endangered. Unfortunately, traditional water treatment methods are ineffective in the degradation of most OMPs. In recent years, advanced oxidation processes (AOPs) techniques have received extensive attention for the mineralization of OMPs in water in order to avoid serious environmental problems. Cold atmospheric plasma discharge-based AOPs have been proven a promising technology for the degradation of non-biodegradable organic substances like OMPs. This paper reviews a wide range of cold atmospheric plasma sources with their reactor configurations used for the degradation of OMPs (such as organic dyes, pharmaceuticals, and pesticides) in wastewater. The role of plasma and treatment parameters (e.g. input power, voltage, working gas, treatment time, OMPs concentrations, etc.) on the oxidation of various OMPs are discussed. Furthermore, the degradation kinetics, intermediates compounds formed by plasma, and the synergetic effect of plasma in combination with a catalyst are also reported in this review. GraphicAbstract

“…In 1938, Yutkin [1] proposed the industrial applications of high voltage electrical pulses. Since then, the high voltage electrical pulse technology has seen significant developments and successful applications in many fields, such as sewage treatment [2,3], hydraulic electric sand cleaning [4], extracorporeal lithotripsy [5,6], rock fragmentation [7], oil reservoir removal and fracture creation [8], and new nanomaterial synthesis [9].…”
