The Comparison between types of electrodes in Dielectric Barrier Discharge (DBD) plasma for obtaining potable water: a review

Abstract

Water is a basic human need in everyday life. However in some areas consumable clean water is still unattainable. There is an urgent need for water purification equipment. Several researches on water purification devices has been carried out with different methods. One of the methods amongst them is using the Dielectric Barrier Discharge Reactors. This method applies appropriate temperatures to make it safe for use. This paper discusses about the various methods used in water purification. The previous researchers discussed a lot about the parameters of the ozone producing capability. They also explained the characteristics and effects of voltage related to voltage sources. Furthermore, the factor of non-potable water is also used as a research material. Based on these previous researches, the researcher reviewed and investigated two of the types of electrodes used - The screw and helix type. They were examined in the same reactor tube length, thickness and tube material dimensions.

Sustainable Plasma‐Catalytic Nitrogen Fixation with Pyramid Shaped μ‐Electrode DBD and Titanium Dioxide

“…Previous studies have explored different electrode shapes such as pyramid-shaped spikes, spiral electrodes, double hexagons, and conical electrodes. [27][28][29][30][31][32] However, these studies primarily focused on the shape of the electrodes rather than their sharpness. It is assumed that such a micro-level sharpness on the end of the electrode acts as a charge emitter, which can promote a higher rate of secondary electron emission and field emission due to the intensified local electric field.…”

“…The shape of the electrode used in the plasma source plays a crucial role in determining how the plasma behaves and its characteristics. Previous studies have explored different electrode shapes such as pyramid‐shaped spikes, spiral electrodes, double hexagons, and conical electrodes [27–32] . However, these studies primarily focused on the shape of the electrodes rather than their sharpness.…”

Study the Effect of Dielectric Barrier Discharge (DBD) Plasma on the Decomposition of Volatile Organic Compounds

“…Surface discharge (SD) is the discharge that takes place on the dielectric surface, whereas volume discharge (VD) fills the space between the electrodes. The intensity of the light on the dielectric surface is caused by the discharge that is produced [4]. There are many uses for DBD plasma; one of these is its use in the decomposition of compounds.…”

“…In this work, the properties of the plasma generated by the dielectric barrier discharge (DBD) system and by a glass insulator were studied. Plasma was generated at different voltages (3,4,6,7, 8 Kv) with a fixed distance between the electrodes of 5 mm, and a constant argon gas flow rate of 2.5 L/min. DBD plasma emission spectra were recorded for each voltage.…”

Thermodynamic Simulation in Eco-Friendly Aquadest Production Through Compression System Method Combined with Steam Power Plant as Heat Source

“…The use of Dielectric Barrier Discharge Reactors is one of these ways. This approach uses the necessary temperatures to make it safe to use [15]. Surajbhan Sevda and colleagues They purified water using microbial respiration and increased the volume of a single seawater desalination chamber from 3 ml to 15 L [11].…”
