The Research was focussed on the effectiveness of a bacterial consortium to the bioremediation of industrial waste water containing dye textiles blue Remazol, in which it has successfuly been done. The aim of this study was to determine the effectiveness of consortium of bacteria on bioremediation of textile waste water which contains Remazol blue dye.  The process was to clearly find out how the  bacterial consortium’s capability in degrading the textile industry wastewater in which the blue dye Remazol is contained. The research was carried out experimentally using Randomized Complete Block and some  factorial treatments. These two treatment factors comprises of two types, they are: a). The type of microbial consortium consisting of the Consortium of Bacillus coagulans, B. pumilus, B. subtilis, and Nitrosomonas sp.; consortium of bacteria Bacillus licheniformis, B. pumilus, B. subtilis, Pseudomonas putida, and Nitrosomonas sp and a consortium of Paenibacillus amylolyticus bacteria, Nitrosomonas, B. circulans, and B. pumilus and b). The factor of the consentration of Remazol blue on industrial wastewater. This particular textile wastewater containing Remazol blue with concentrations in which containing 200 ppm, 1000 ppm and 2500 ppm. The parameters of the study was BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), TSS (Total Suspended Solid) and decolorization efficiency. The data has been analyzed quantitatively. The results have shown that Bacillus coagulans, B. pumilus, B. subtilis, and Nitrosomonas sp. became the most effective consortium in degrading remazol blue in textile wastewaster. The evidence revealed that the higher concentration of remazol blue on wastewater, the smaller degradation effectiveness was resulted by the consortium. The consortium of Bacillus coagulans, B. pumilus, B. subtilis, and Nitrosomonas sp. was able to degrade textile industrial wastewater with a maximum concentration of remazol blue up to 2500 ppm and the bacterial consortium was able to decolorize of Remazol blue that reaching to 84.9%; reducing the levels of Biochemical Oxygen Demand (BOD) to 57.9%; reducing Chemical Oxygen Demand (COD) of 37.7%; and finally reducing Total Suspended Solid (TSS) more or less of 52%.
