PEMBUATAN DAN PENGUJIAN ALAT PEMBANGKIT LUCUTAN PLASMA UNTUK PENINGKATAN BAKU MUTU AIR LIMBAH TEKSTIL

Textiles Industry is one of the leading industries and is an industries that will keep on growing due to the large market offered in Indonesia especially Bandung. However, the industry produces wastewater often times not correctly treated and could be dangerous to environment. BOD concentration number in the test object textiles wastewater was almost double the requirements of the maximum allowed BOD level established by Regulation of The Minister of Environment and Forestry Republic Of Indonesia Number P.16/MENLHK/SETJEN/KUM.1/4/2019. Plasma Treatment offers a rather effective procedure to increase quality of wastewater and have been developing for decades now. Non-Thermal plasma produced by high voltage through electrodes gives electron reaction to oxygen which could be used to produce active species which will oxidize organic material. The experiment produce a non-thermal plasma produce by a high voltage and electrodes gives up to 83% reduction of BOD number, pH decrease to 4,72%, TDS increase to 6,57%, as well as reducing appearance of colour. This can be made possible because of the active species produced by gas phase plasma.
