DEKOLORISASI ZAT WARNA AZO MENGGUNAKAN ADVANCED OXIDATION PROCESS BERBASIS OZON

نویسندگان

چکیده

Industri tekstil dalam proses manufakturnya, membutuhkan air jumlah yang sangat banyak dimana kurang lebih 70% dari tersebut akan berubah menjadi limbah. Limbah cair industri diketahui mengandung senyawa warna sulit terdegradasi sehingga dapat menyebabkan permasalahan nilai estetika di badan penerima, membahayakan keanekaragaman hayati dan bahan toksik karsinogenik mengganggu kesehatan manusia makhluk hidup lainnya. Kebanyakan Kawasan Bandung membuang limbahnya ke Sungai Citarum Hulu zat berupa azo. Salah satu teknologi pengolahan lanjutan untuk dekolorisasi adalah Advanced Oxidation Process (AOP) dengan ozon (O 3 ) mampu limbah efluen tekstil. Proses ozonasi dilakukan pada reaktor bervolume 16 L secara batch R eactive Black 5 (RB5), Reactive Yellow (RY), Blue (RB) variasi konsentrasi mg/L, 10 15 mg/L dosis 7,44 mg/menit 22,32 mg/menit. Dekolorisasi RB5, RY, RB mencapai 100% sebesar RB5 99,77% sedangkan RY 100%. Hasil terlarut terukur rendah menunjukkan bahwa telah bereaksi mengoksidasi senyawa-senyawa organik terkandung Penyisihan COD terbesar didapatkan mg/menit, yaitu percobaan azo terbaik berturut-turut RB>RY>RB5.

The kinetic study of the AZo Dye Decolourisation by advanced oxidation process

In the present study, advanced oxidation treatment, UV/ was applied to decolourisation of Acid Orange 8 (AO8). The UV radiation was carried out with a 15 W low-pressure mercury lamp. Kinetic model for the decolourisation of the dye was developed based on experimental results and known chemical and photochemical reactions. The observed kinetic reaction constant was determined and correlated as a...

UV/ H2O2 Advanced Oxidation Process for Simultaneous Removal of NO and SO2: A Review

This study presents a review on advanced oxidation processes (AOP) for simultaneous removal of NO and SO2. AOP is based on using a strong oxidant such as ozone and H2O2 which is able to generate highly reactive intermediates. The pollutant will be oxidized and removed by these intermediates. In recent years, AOP has been considered as an effective and attractive technology in the field of flue ...

Advanced Oxidation Process for Haloacetic Acid Removal in Tehranpars Water Treatment Using CuO Nanocatalyst

Potentially harmful disinfection byproducts (DBPs), as a significant challenge in water treatment, are formed when oxidizing disinfectants react with natural organic matters (NOM). Unfortunately, an  unwanted  side  effect  is  the  formation  of  harmful by-products,  such  as  THMs  and  HAAs, following the chlorination stage. DBPs  cause a variety of diseases like cancer in humans.  In this ...
