Evaluation of a Microbial Consortium and Selection of a Support in an Anaerobic Reactor Directed to the Bio-Treatment of Wastewater of the Textile Industry

The dyeing processes of the textile industry generate waste products such as unfixed dyes, phenolic surfactants and heavy metals. These constitute an environmental problem for bodies receiving their wastewater due to interruption lighting in aquatic environment release toxic molecules by decomposition dyes. There are several treatment methods, which biological methods most feasible. In current study, I5-ESPE microbial consortium was obtained evaluated on components wastewater, addition selection a support anaerobic reactor that is directed effluents from industry. Two consortia were achieved exposure air Pseudomonas culture medium modified with direct dyes Red 23 Blue 106, evaluating removal capacity reactive Navy 171, 141 Yellow 84. selected its greatest action, yielding approximately 95% removal. Its tolerance phenol also determined; we reached 98% chromium(VI) 67% total chromium under conditions some 25% zinc aerobiosis. reduction chemical oxygen demand (COD) (57.03%) without (31.47%) aeration. species Staphylococcus xylosus, Saccharomyces cerevisiae Candida tropicalis identified prior well Enterobacter cloacae Bacillus megaterium after treatment. subtilis present throughout process. We coconut shell reactor, it demonstrated better physical characteristics than plastic common rock, similar results COD 50%, volatile suspended solids 2545.46 mg/L 282.82 mg/L.
