Abstract

The objective of the prototype is to eliminate the polluting contamination of water sources, due to the leak of industrial waste without any kind of treatment, mainly generated by the industries and home sector. In this project, a prototype of water purification by plasma technology has been designed. The prototype will convert contaminated water into the plasma stream and eliminate the pathogens from the water by exposing it to ultraviolet radiation and plasma sterilisation. The polluted water will be accelerated at high speed using a water pump in order to convert it into a liquid-gas mixture for ease plasma generation. This process will be achieved when the electric supply from a source of alternating current (AC) is applied to the water by means of high voltage electrodes. After which, the mixture slows down to return into liquid form and the clean water is obtained. The whole process takes place without significantly raising the temperature also knows as non-thermal plasma. The device also has an automatic flow and pressure control system. Finally, a short feasibility study has been conducted on the water samples collected and report obtained from Chennai Metropolitan Water Supply and Sewage boards are reported. It has been concluded that this new plasma-based water treatment system will be more efficient and cheaper than the current wastewater treatment techniques and can be used in the future as the replacement of current secondary and tertiary treatments of industrial wastewater.

Comment: Can u give more details on power supply simulation in LTspice?
Otherwise very good article.

Comment: LTspice is open source spice simulation software and here advantage is we can design our own transformer. In the supply circuit, I use flyback driver coupled with the custom build flyback arrangement. For better understanding, you can check the supplementary file section simulation.

Comment: I saw the table in the result, Did you did this in your university lab or in Chennai Metropolitan Water Supply and Sewage boards. Is there is any proof for lab result?

Comment: All test was conducted in and by Chennai Metropolitan Water Supply and Sewage boards. I only mentioned the major test result in the paper. The test is there in the more info file.
