Proses pengolahan limbah cair industri tekstil dengan pewarna indigo dapat dilakukan dengan proses oksidasi oleh ozon gelembung mikro. Dalam penelitian ini, limbah yang digunakan merupakan limbah cair industri tekstil yang telah mengalami pengolahan limbah dengan proses koagulasi kimia. Proses tersebut kemudian dilanjutkan dengan pengolahan limbah menggunakan ozon gelembung mikro untuk meningkatkan proses oksidasi guna mendegradasi pewarna indigo pada limbah cair tekstil tersebut. Pengolahan limbah cair tekstil dengan pewarna indigo dilakukan dengan proses oksidasi menggunakan ozon gelembung mikro yang berukuran 61 -80 µm. Generator ozon gelembung mikro dibangkitkan dengan menyisipkan ozon pada aliran sirkulasi 20 liter limbah cair tekstil melalui pipa venturi dengan diameter 6,35 mm sebanyak 4 buah. Ozon dibangkitkan melalui reaktor lucutan berpenghalang dielektrik dengan nilai kapasitas ozon yang dapat divariasikan. Penelitian ini menggunakan nilai kapasitas ozon sebesar 50,4 g/jam, 67,7 g/jam, dan 86,4 g/jam. Setiap nilai kapasitas ozon yang digunakan untuk pengolahan limbah cair tekstil divariasikan dengan waktu pengolahan limbah selama 60, 120, 180, dan 540 menit. Hasil pengolahan limbah cair tekstil dengan proses oksidasi menggunakan ozon gelembung mikro menunjukkan bahwa pewarna indigo dalam limbah cair tekstil mampu tereduksi optimum menggunakan nilai kapasitas ozon sebesar 86,4 g/jam dan waktu pengolahan limbah selama 540 menit. Hal tersebut menunjukkan bahwa semakin lama waktu pengolahan limbah dan besar nilai kapasitas ozon yang digunakan maka proses degradasi pewarna indigo semakin tinggi.

“…Using Dielectric Barrier Discharge (DBD) as a plasma generator has been used in a variety of research and development projects. DBD is a type of low-temperature plasma that can be used in different applications, including the environment, DBD actuator, ozone generators, and more [1]. Brandenburg studied the plasmas generated in configurations with an insulating (dielectric) material between the electrodes which is responsible for a selfpulsing operation [2].…”

In this work, one configuration was used to study the electrical discharge resulting from the dielectric barrier. This configuration consists of a sheet of epoxy/Al composite with dimensions of 75 mm in length, 25 mm in width, and 3 mm in thickness. This panel is located at the center of the electrodes, so that the distance between each of the electrodes and the plate is 2 mm and plasma is generated at these distances. The relationship between voltage and current with changing the frequency of the equipment as well as changing the area of exposure to the upper electrode or changing its length has been studied. The length of the top electrode varies at 0, 10, 20, 30, and 40 mm from the center of the electrodes producing exposure areas of 1875, 1625, 1375, 1125, 875, and 625 mm2, respectively. Two frequencies of 8 and 9 kHz were applied in this work. The results showed that the discharge current increases linearly with the applied input voltage and with the decrease of the exposure of the upper electrode. Then, the current increases with the stability of the voltage in varying proportions depending on the exposure area and frequency. The plasma generated from this modulation was diagnosed with the exposure area and the fitted frequency. Electron temperature and electron density are calculated using the optical emission spectroscopy technique by Boltzmann and Lorenz, respectively. It can be seen that the temperature, electron density, and plasma frequency increase with the decrease of the exposure area, while the Debye length shows the opposite behavior and this is clear in this formation and high effectiveness at Diagnosis and Reason This formation will be adopted in the surface treatment of the aluminum epoxy compound.
