An overview of plasma treatment Environmental science essay
In recent years, plasma fluid systems have attracted significant attention from researchers in a variety of application domains, including environmental and wastewater remediation, 7, 8, nanomaterial processing, 9, 10, cancer cell treatment, 11 sterilization and disinfection, 12 bacterial prevention and eradication. biofilms 13 and there is an urgent need to control emissions of volatile organic compounds, VOCs, due to their harmful effects on the environment and human health. A hybrid system integrating non-thermal plasma and catalysis is considered one of the most promising technologies for VOC removal due to its high VOC removal efficiency and product selectivity. Other authors have conducted more complete LCA studies covering a wider range of environmental categories for the plasma gasification of MSW, confirming the technological advances and environmental benefits reported by this technique compared to incineration 69, fast pyrolysis, conventional gasification and landfills 53 as there are short-term and long-term adverse effects on human health are observed. VOCs are responsible for odors in indoor air. Short-term exposure has been shown to cause irritation of the eyes, nose, throat and mucous membranes, while long-term exposure can cause toxic reactions. 92 The aquaculture sector is developing rapidly and generates a large amount of waste water. Domestic aquaculture wastewater contains nutrients and other substances that can cause eutrophication and the emergence of resistant organisms if released into the environment. Therefore, aquaculture wastewater must be properly treated for reuse. Plasma treatment can be carried out via direct current direct current or alternating current alternating current using low frequency 1 - radio frequency RF 56. and microwaves, MHz. energy 66, 71. Plasma can be produced at low pressure in a closed chamber or at atmospheric pressure. The effects of untreated water and plasma activated water treated minutes on soybean germination and growth were studied. The germination rate appeared to be higher with plasma treatment. This work provides an overview of the current status of research on cold plasma treatment of catalytic materials. The focus is on physical and chemical processes during plasma processing, the processing mechanism of the catalytic materials, as well as the future challenges in this dossier. Export citation and summary BibTeX RIS.Abstract. CP cold plasma technology has proven to be very effective as an alternative tool for sanitizing food and extending shelf life. The impact of CP on food quality is critical to its acceptance as an alternative food processing technology. Due to its non-thermal nature, CP treatments have no or minimal impact on the plasma jet: an overview. and comparison with other plasma sources. Andreas Sch. utze, James Y. Jeong, Steven E. Babayan, Jaeyoung Park, Gary S. Selwyn, and Robert F. Hicks. In this experiment, an inverse gas-liquid two-phase discharge water treatment device was independently designed to treat the actual intermediate dye wastewater of a chemical plant. First, the effects of the initial concentration of the wastewater, the initial pH, the solution circulation rate, the Fe2 content, the H2O2 content, and in addition. The use of plasma-activated water PAW treatment is a promising technology that offers many advantages, such as high efficiency, flexibility, environmental safety and no residue. For example, PAW is applied in the agricultural sector to...,
