Pengolahan Air Limbah Tekstil Berbasis Ozonisasi Katalitik Dengan Katalis Besi(III) oksida (Fe2O3) dan Aluminium oksida (Al2O3) Menggunakan Difuser Mikro

Rame Rame, Agus Purwanto, Agung Budiarto

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 Al2O3 dengan 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.
