Abstract

Proses oksidasi lanjut (AOP) merupakan teknologi pengolahan air limbah industri tekstil yang sangat potensial. Kelemahan teknologi ini adalah pemakaian H₂O₂ yang berimplikasi pada biaya operasional dan peningkatan kadar keasaman. Teknologi ozonisasi katalitik terintegrasi katalis Fe₂O₃ dan Al₂O₃dengan difuser mikroadalah alternatif solusi yang murah dan efisien. Ozonisasi katalitik dilakukan dengan variasi dosis katalis 500 g, 1000 g, 1500 g dan flow ozon 1, 2, 3, 4 L/menit dengan volume air limbah 20 L. Optimalisasi proses ozonisasi katalitik dilakukan melalui variasi waktu kontak. Kinerja fungsi katalis diukur berdasarkan umur pemakaian. Indikator kinerja reaktor diukur dengan parameter warna, suhu, TSS, COD, dan BOD₅. Kondisi ozonisasi katalitik terbaik untuk dosis katalis 500 g Fe₂O₃, 500 g Al₂O₃, waktu ozonisasi katalitik 20 menit dengan flow ozon 2 L/menit.
