“…Expected transformations were not obtained even though the sintering process was carried out at temperatures reported in the literature. This could be due to the presence of more amounts of quartz (present in the sludge), which prevents the phase transformations from occurring at the expected temperature …”

The sludge of a wastewater treatment plant of a tobacco processing agroindustry is a waste material, and although it is not considered a hazardous waste, its disposal must occur in landfills, which causes high costs. Therefore, a thorough study to find a suitable destination for the sludge is necessary. In this work, this sludge and red clay were prepared in different formulations, uniaxial compacted and fired at 950, 1050 and 1150°C to evaluate the effects of the incorporation of sludge to obtain ceramic materials and to verify the potential application in the construction industry. Water absorption increases with sludge content (due the evolvement of gases related to the decomposition of hemicellulose and lignin present in tobacco) and decreases with higher firing temperatures, ranging from 9.55% to 20.10%. Values of mechanical resistance ranged from 7.23 to 1.84 MPa at a firing temperature of 950°C, 7.58 and 1.78 MPa at 1050°C and 6.94 and 3.97 MPa at 1150°C. The results show that ceramic materials obtained are promising in the production of masonry blocks. The use of the sludge reduces the environmental impacts that may be caused by waste and decreases the amount of raw material extracted from nature.

The disposal of sludge generated by water treatment by chemical coagulation is considered an environmental problem that has attracted attention of researchers worldwide, whose objective is to promote strategies for their productive use. This study addresses results of studies conducted in the recent 7 years on the aluminous sludge use in the manufacture of ceramic products. The literature shows that the proportion of sludge and the firing temperature are two key factors that affect the final ceramic products technological properties: water absorption, mechanical resistance, porosity and bulk density. It is concluded that it is feasible to incorporate water treatment sludges in partial replacement of one of the constituent materials of clay bodies, with additions up to 10% sludge and firing temperatures above 1000 °C.

The removal of cadmium by ceramics surfaces was investigated to evaluate sorption effectiveness of these materials in residual waters. The effects of solution pH, contact time, metal concentration and dose of sorbet material were studied in batch experiments. Ceramic material was compositionally and morphologically characterized before and after the removal of cadmium by scanning electron microscopy to establish the metal sorption Sorbent material was also tested in residual water with high cadmium content, achieving a 98% removal efficiency.
