This work deals with the development and implementation at laboratory scale of a methodology for the treatment of wastewater from a textile factory, usin Sequencing Batch reactors (SBR) - and activated sludge process based on biological reactors - and the evaluation og its efficiency. To verify the efficiency of the proposed method (or process), the following parameters were evaluated, TSS (Total Suspended Solids), Color ADMI, COD (Chemical Oxygen Demand) and DOC (Dissolved Organic Carbon). The results indicate efficiencies in the range 60 to 70 % for each one of the parameters considered in this study.
