The treatment of water from Anapolis - GO generates as major waste sludge in the decanter after alkalinization, coagulation, flocculation and sedimentation, and washing water after backwashing of the filters themselves. This work was carried out physical-chemical and bacterial waste by means of the methods prescribed in Standard Methods for the Examination of Water and Wastewater. The results indicate the need for treatment and proper disposal of sludge to the decanter, as its parameters do not meet the standards required for discharge of effluents into water bodies. While the characteristics of the wash water filters are close to the standards of water quality class 2, set by the CONAMA Resolution 357. These results demonstrate the need and the importance to waste characterization.
