Analysis of Textile Dyes Wastewater Treatment Using Plasma Corona Discharge with Needles-Planes Reactor

Abstract

Environmental pollution caused by the textile industry that disposes of wastewater carelessly becomes a severe problem. The colored wastewater comes from dye residue in textile wastewater. In response to that problem, the proper treatment is necessary, namely by using plasma corona discharge. Methylene Blue and Remazol RB Red were used as synthetic wastewater for removal experiments. The research shows that in Methylene Blue under acidic conditions a decrease in concentration occurs until it has a final concentration with a removal percentage reaching 74.64%. In Remazol RB Red dye in alkaline conditions, a decrease in concentration occurs until it has a final concentration with a percentage decrease of 29.83%. An increasing number of H + ions in the solution causes a decrease in pH. The TDS value decreased only under acidic conditions. In Methylene Blue dye, there was a decrease of 374 ppm using oxygen. While in Remazol RB Red, the decreased until 372 ppm with the use of oxygen. The EC value decreased under acidic conditions. In Methylene Blue dye, there was a decrease to 396 µS/cm using oxygen. While in Remazol RB Red, the decrease to 432 µS/cm with the use of oxygen.
