Abstract
Non-thermal plasma jet has been emerged as a promising technology for water treatment due to its ability to generate highly reactive species that can oxidize and break down contaminants in water. In this study, we investigated the effectiveness of non-thermal plasma jet for water treatment. The experimental setup consisted of a jet reactor, which was used to generate plasma, and a water treatment system, which was used to deliver water to the reactor.
The effects of various parameters such as plasma power, treatment time, and initial contaminant concentration on the removal efficiency were studied.
The results showed that non-thermal plasma jet was effective in removing organic and inorganic contaminants from water, with removal efficiencies of up to 98% for iron compounds and 84% for copper compound,71% removal for industrial pigments and 78% for organic compounds as phenol. The removal efficiency increased with increasing plasma power and treatment time, and decreased with increasing initial contaminant concentration especially in the case of industrial pigments.
The optimal conditions for water treatment varied depending on the type and concentration of contaminants. The results suggest that non-thermal plasma jet may be a promising technology for water treatment, offering a cost-effective and efficient method for removing contaminants and improving the quality of water.
Here are some additional details and considerations for the use of non-thermal plasma jet for water treatment:
The design of the jet reactor is critical for achieving efficient water treatment.
The reactor should be designed to provide maximum contact between the plasma and the water to be treated, while minimizing energy consumption and avoiding the formation of harmful byproducts.
The reactor may be made of various materials, such as quartz, glass, or ceramic, and may incorporate various electrode configurations to generate the plasma.
Non-thermal plasma jet technology can be effective in removing a wide range of contaminants from water, including organic compounds and inorganic compounds.
The technology works by generating highly reactive species, such as hydroxyl radicals, which can oxidize and break down the contaminants. The effectiveness of contaminant removal depends on various factors, including the type and concentration of contaminants, the plasma power, and the treatment time.
One of the advantages of non-thermal plasma jet technology for water treatment is its low energy consumption compared to other treatment methods, such as UV and ozone. However, the energy consumption can still be significant, particularly for large-scale applications. Energy efficiency can be improved by optimizing the reactor design, plasma power, and treatment time.
Applications:
Non-thermal plasma jet technology has potential applications in various water treatment settings, including drinking water treatment, wastewater treatment, and industrial water treatment.
The technology can be used to remove contaminants, disinfect water, and improve water quality for various purposes, such as irrigation and industrial processes. Further research is needed to optimize the technology for specific applications and to evaluate its long-term effectiveness and sustainability.
Overall, non-thermal plasma jet technology offers a promising approach to water treatment, providing a cost-effective and efficient method for removing contaminants and improving the quality of water.
By optimizing the reactor design, operating conditions, and treatment parameters, non-thermal plasma technology can be further developed and applied to various water treatment settings to improve water quality and protect public health and the environment.
