The slugde from decanters in Water Treatment Plants (WTP) has different composition varying, according to the region, coagulant type and dosages, the plant layout. In this work, the physical characterization of the sludge generated from decenties (ETAII the municipality of Rio Claro, Brazil), the manufacture of bodies of evidence-sludge mixture of clay (with humidity of 8% and concentrations of sludge, 5, 15 and 30%) the testing technology after burning the mixture to a temperature of 950 ° C were investigated. The main aim assess the possibility of its use as raw material in the ceramic red production. For comparison of the obtained results it was used values of the testing technology of bodies of evidence only with clay, prepared under the same conditions. In general, the addition of sludge from ETA made worse the properties of the ceramic body, however, the values obtained from the tests on the concentration of 5% of sludge, still remain within the acceptable limits for the production of red pottery pieces.
