It discharges enormous quantity of highly colored wastewater due to the use of water in large quantity and the use of dyes in the production process. One of the problems in processing textile wastewater with conventional biological treatment method is the ineffectiveness of color removal. A further treatment as post treatment is needed for treated wastewater discharge to remove the color. One of the method that known has high efficiency for textile color removal is by using ozonation method. In this ongoing study, the decolorization of artificial textile wastewater containing azo dye reactive-black 5 (RB5) from secondary treatment was investigated in a continuous system. Artificial treated textile wastewater from secondary biological treatment is made using 5 mg/L azo dye RB5 in 16 L volume batch reactor. The experiments show that the efficiency of color removal achieved is 100% within 10 minutes of reaction time with 24.66 mg/minutes of ozone dosage. In continuous system operation, ozonation process also conducted in 16 L volume reactor with up flow and down flow of influent feeding and HRT 10 minutes, 30 minutes and 50 minutes. The experiments show that the color removal was fluctuate Andromeda oscillation in certain interval contact time for each HRT, but higher color removal efficiency achieved in HRT 50 minutes.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Biological treatment methods,Color removal efficiency,continue system,decolorization,Post treatment,Secondary biological treatments,Secondary treatment,Treated wastewater[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]azo dye,COD,continue system,decolorization,ozonation,post treatment,RB 5[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The study was performed within the ITB-P3MI research scheme; a research programs on community service, and innovation on ITB research group which is co-funded by the Indonesian Ministry of Research, Technology and Higher Education (Ristek-Dikti) Research Grant Fiscal Year 2018.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1757-899X/536/1/012069[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
