“…Several previous researches have demonstrated the potential effectiveness of plasma discharge in decontaminating wastewater by significantly lowering the amount of certain aqueous pollutants up to a remarkable level. Besides this, researchers have noticed a consequential reduction in several water-borne pathogenic microorganisms including viruses (Wang et al 2015;Patange et al 2018;Ma et al 2020;Guo et al 2018). Similarly, Guo et al (2020) recently demonstrated substantial inactivation of S protein in plasma activated water to inhibit coronavirus transmission.…”

“…To overcome these limitations of conventional methods, technologists are more concentrated towards establishment of modern oxidation processes like cold plasma technology (Wang et al 2015;Duan et al 2015), photo-Fenton techniques (Ameta and Ameta, 2018), photocatalysis (Vaiano et al 2017;Vaiano and Iervolino 2018), ozonation (Saeid et al 2018), electrochemical reactions (Garcia-Segura et al 2018), irradiation technology (Bisht et al 2021;Pricaz and Uta 2015) or a combination of these for treating wastewater followed by microbial inactivation. All such techniques undergo the process of mineralization, causing decomposition of various organic pollutants, i.e.…”

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.

Changing consumers’ taste for chemical and thermally processed food and preference for perceived healthier minimally processed alternatives is a challenge to food industry. At present, several technologies have found usefulness as choice methods for ensuring that processed food remains unaltered while guaranteeing maximum safety and protection of consumers. However, the effectiveness of most green technology is limited due to the formation of resistant spores by certain foodborne microorganisms and the production of toxins. Cold plasma, a recent technology, has shown commendable superiority at both spore inactivation and enzymes and toxin deactivation. However, the exact mechanism behind the efficiency of cold plasma has remained unclear. In order to further optimize and apply cold plasma treatment in food processing, it is crucial to understand these mechanisms and possible factors that might limit or enhance their effectiveness and outcomes. As a novel non-thermal technology, cold plasma has emerged as a means to ensure the microbiological safety of food. Furthermore, this review presents the different design configurations for cold plasma applications, analysis the mechanisms of microbial spore and biofilm inactivation, and examines the impact of cold plasma on food compositional, organoleptic, and nutritional quality.

“…In the exploration of gas reservoirs containing water, a scaling problem is usually created which severely affects the production of gas wells [1,2]. Due to the change of production conditions, such as the chemical reactions in the electrolyte solution and phase changing between oil, gas, and water [3,4], the scaling formation of gas reservoir fluid is very complicated. Not only will the scaling conditions of inorganic salts themselves change with the change of temperature and pressure but also the dissolution, precipitation, and evaporation of oil and gas components will severely affect the scaling trend of inorganic salts.…”

During the exploitation of a gas reservoir containing water, the scaling problem is usually affecting the gas production in gas wells. Although the scale formation that occurs during oil field development is quite different from the aforementioned gas field, the phase behavior plays a pivotal role in the formation of inorganic scale in gas field development. It is a well-known fact that there is no device that can directly measure the extent of scaling formation in a high-temperature and high-pressure reservoir. At the same time, the commonly applied scaling prediction method does not account for the fluid phase state. In this work, the scaling condition and alteration in controlling parameters in an actual gas reservoir were studied by self-developed high-temperature and high-pressure formation fluid equipments. From thermodynamics, a new scaling prediction model for the multiphase equilibrium of gas reservoir fluid is proposed that considers gas, liquid hydrocarbon, formation water, and inorganic salt scale. For the complexity of the direct solution for a phase equilibrium system with a chemical reaction, a simplified method for calculating the phase change and chemical equilibrium in a multiphase equilibrium system with chemical reactions is proposed based on the conservation of materials and the unification of the physical properties of components. The results show that the predicted value of the model was consistent with the experimental results. The new scaling prediction model considered the influence of the phase state which can accurately predict the change of the fluid phase state and the amount of inorganic salt scaling of actual gas reservoir fluids under the condition of multiphase equilibrium. Moreover, the average deviation of the prediction results is about 3%. The predicted scaling amount of the model without considering the effect of phase change is significantly lower than that of the experimental results. More specifically, the average deviation is around 30%. With the decrease of gas reservoir pressure, formation water evaporation intensifies under the influence of the oil and gas phase state, which leads to the increase of the formation water ion concentration when the influence of the fluid phase change is not considered. Then, the prediction of the inorganic salt scaling will be significantly lower.
