Textile wastewater purification using corona discharge method

Abstract

In this study, a textile industry wastewater being researched. Textile industry wastewater can be an environmental problem if it isn’t handled properly. A lot of things contained in textile industry wastewater that have to be processed, such as textile dyes, Total Dissolved Solid (TDS) and acidity (pH). Textile wastewater that dissolved in water in large quantities can increase the turbidity of the water and increase the levels of toxic substances in the water because some textile dye contains carcinogenic chemicals. So, before the textile wastewater being thrown away into the nature, it must be purified first. One of the technologies that is used to process textile industry wastewater is corona discharge plasma technology. This technology utilizes the ozonation process to purify the textile industry wastewater. The corona discharge generated by a high voltage generator with a flyback converter circuit topology. While the electrode configuration in the reactor is needle-field.The textile industry wastewater used is an artificial/synthetic waste which consist of methylene blue. Based on the results, the ozonation process is proven to reduce the concentration of dyes from synthetic wastewater. The greater the number of circulations, the greater the removal ratio of concentration in textile industry wastewater. The level of TDS from the purification process increasing along with the increasing of the circulation. The pH level of the purification results tends to decrease (become acidic) due to chemical reactions that occur in the reactor. The increasing of hydrogen ions formed in the reactor may increase the level of TDS in the wastewater.
