Textile Dye Reactive Black 5 (RB5) Bio-Sorption with Moving Bed BiofilmReactor and Activated Sludge

Abstract

Reactive Black 5 (RB5) is one of the dyes used in textile industries in Indonesia. However, the high color content can interferewith the condition of water bodies if not treated. This waste treatment process is usually treated with biological treatmentprocesses. Biological processing often used is the MBBR unit and activated sludge. This study aims to determine the RB5dye’s bio-sorption efficiency using MBBR processing and activated sludge. MBBR processing and activated sludge consistof seeding, acclimatization, and running stages. This research was carried out using a real textile wastewater approach byadding 100 mg/L RB5 and adding 1000 mg/L starch solution. The processing results of the seeding stage indicate increasingin biomass. The acclimatization stage with 50% and 75% of wastewater indicates increased biomass and color removal.The RB5 color removal efficiency results in the MBBR unit and activated sludge show 41% and 84% values. The MBBRprocessing shows fluctuations each time where the desorption process occurs in the color removal. For this reason, the ozonepre-treatment process is conducted in the MBBR unit. The integrated pre-treatment with MBBR results show the samefluctuation as the previous processing with a color removal efficiency of 43% with a color removal efficiency of 43%.

“…3 Hal ini dapat mengganggu keseimbangan ekosistem sungai salah satunya yaitu terganggunya proses fotosintesis dan penurunan oksigen terlarut. 4 Beberapa teknologi secondary dan tertiary treatment seperti lumpur aktif, 5 moving bed biofilm reactor, 6,7 oksidasi kimia, 8,9 dan adsorpsi 10,11 dapat digunakan untuk mengolah limbah tekstil warna, dengan hasil efisiensi, biaya operasional, dan kemudahan proses yang bervariasi. Salah satu metode yang ditawarkan berupa adsorpsi menggunakan karbon aktif yang terbuat dari bahan alternatif yaitu alga.…”
