Abstract
Laju pertumbuhan penduduk dan perkembangan wilayah meyebabkan kebutuhan air bersih terus meningkat. Diperlukan berbagai solusi agar tingkat ketersediaan air bersih dapat terus memenuhi kebutuhan. Salah satu cara mendapatkan air bersih adalah dengan melakukan pengolahan air menggunakan ozon. Ozon tidak saja digunakan sebagai disinfektan tetapi beberapa manfaat ozon telah digunakan untuk menghilangkan kontaminan yang dapat dioksidasi di dalam air. Ozon dapat dihasilkan dengan beberapa cara yaitu secara elektrolisis, kimiawi, termal atau fotokimia, serta melalui peluahan muatan listrik. Prinsip peluahan muatan listrik adalah dengan melewatkan udara atau oksigen ke sebuah ruang di antara elektroda-elektroda bertegangan tinggi AC. Ruang pembentukan ozon dapat berbentuk tabung dan plat. Peluahan muatan listrik pada ruang pembentukan ozon akan memicu terjadinya ionisasi berupa benturan elektron dan gas oksigen pada udara sehingga menghasilkan ion-ion oksigen. Reaksi antara ion-ion oksigen dan gas oksigen lainnya akan menghasilkan gas ozon. Gas ozon yang dihasilkan akan dimanfaatkan untuk penjernihan air. Pada penelitian ini akan diamati pengaruh intensitas medan listrik, debit aliran udara dan jumlah pasang elektroda terhadap efektivitas dalam penjernihan air. Dari hasil penelitian menunjukkan bahwa semakin besar medan listrik maka semakin efektif penjernihan air, semakin besar debit aliran udara maka semakin tidak efektif penjernihan air, dan penerapan multi elektroda lebih efektif dalam penjernihan air.
English Abstract
This study reports the results of research on water purification using high voltage generation with multi electrodes and multi air gap to optimize ozone gas generation. Ozone gas is produced through the ionization process due to an electric discharge with a high electric field in the plate-shaped ozone production chamber which is flowed with air. The high voltage source used in this research to generate a high electric field is HVAC. The method applied to generate a high electric field using the dielectric rasio method. The principle used in this method is partial discharge. Because there are differences in the relative dielectric coefficients of the layered dielectric arrangement, in this research using acrylic and air dielectrics, the electric field strength that arises in the air gap will be very large when given a high voltage compared to the acrylic layer. The strength of generated electric field in the air gap is influenced by the relative coeeficient, layer thickness, voltage and others. The method used in this research is to design an ozone production chamber with multi electrodes and multi air gap compared to the conventional design to optimize the generation of ozone gas. So that in this research there are two models of ozone production chambers, a pair of electrodes and multi electrodes. Both models have the same dimensions with a total length of 48 cm and a total width of 30 cm. For each layer, the acrylic thickness is 6 mm, the air gap is 1 mm, and the aluminium electrode is 2 mm. The variables observed in this research is the effect of voltage, air flow rate, and the number of pairs of electrodes on the effectiveness of water purification. The variations used for testing is voltage of 25 kV and 30 kV, air flow rates of 10 L/min and 20 L/min, and the number of pairs of electrodes in the form of a pair of electrodes and multi electrodes. This research was conducted at the High Voltage Engineering Laboratory Electical Engineering Brawijaya University as a place that provides high voltage alternating current generation testing. The results showed that the greater the electric field, the more effective the water purification was, the greater the air flow rate, the less effective the water purification was, and the application of multi electrodes was more effective in water purification. Keywords: ozone, electric field, air flow rate, multi electrodes.
