CHARACTERIZATION AND EVALUATION OF THE POTENTIAL USE OF SLUDGE FROM STP AND WTP IN PAVING

The STP sludge residue has high organic matter content, which was confirmed by chemical analysis that found different oxides within the sample.

March 04, ; Accepted: The clay mass was obtained from the mixture of four clays that was collected after complete homogenization and removal after the rolling process. The surfaces set by ant of the compound model for mixtures of soil with both sludge residues are shown in Figure 7.

This plant has a nominal capacity of about 80,m 3 sewage per day. The panel component is the heaviest part and it contains elements such as barium, strontium, and yttrium.

Surface horizon consists of granular soil – sandy bould gravel – with a depth of around two meters. It is noted that reference values are part of the service specifications for being used in roads with heavy traffic, i. Future studies should evaluate the hazardousness potential of other elements such as barium and strontium.

The amount of sample prepared was 1 kg for each formulation and then homogenized manually with the help of a metal spatula and then an eccentric mixer. Standard methods for the examination of water and wastewater.

Table 4 presents the results of the Raw Residue of the STD and enamel waste, showing that the residue used has a smaller particle size than the standard mass, directly aiding in the packaging factor, contributing to a better compaction. The XRF results from CRT parts confirmed that lead is present in the funnel and in the neck while the panel is lead free, as abmt in Table 4.

The WA was classified as Class IIa not inert with the values of the chromium, cadmium, and lead annt the maximum limit. Abstract Cathode ray tube CRT monitors are electronic equipment mainly made of glass, polymers and metals.

Such a productive increase demands a large amount of raw material which generates environmental problems related to the scarcity of natural resources. BeforeCRT did not use high voltage in the electron gun, and thus, did not need as much lead in the glass for shielding Webster, The presence of other compounds can be explained by the presence of impurities because of the residue nature.

MedCrave Group is ardent to provide article reprints at an instant affordable Read more Rainy seasons tend to produce higher amounts abnf to water infiltration, as well as STPs near industrial parks, where treated effluent are deposited.

This work also contributes to the reduction of the environmental impact and favors the sustainable development of the heavy clay ceramics contributing to the improvement of the quality of the pieces.

The mechanical strength had a significant increase compared to the standard mass, as the residue content was increased the water absorption decreased wbnt the resistance increased. The solutions obtained from the procedures were analyzed abt atomic absorption spectroscopy and the results were compared to the limits shown in NBR The analyzed waste is considered as class I—Dangerous due to the presence of toxic elements in the leachate above the Brazilian waste classification standard.

Materials and methods 2.

The parameters of sbnt compound models referring to the mixtures are shown in Table 6. Ten samples were pressed for each formulation in a total of 60 samples at a pressure of 5 tons. The sanitation in this country is still precarious.

The results of mechanical strength obtained by the diametrical abmt method and the water absorption presented in the graph Figure 4. The standard NBR procedure was performed for 7 different monitors.

Revista Escola de Minas, 68 3 Environmental profile of ceramic tiles and their potential for improvement. This decrease was expected due to the nature of the samples, which have organic matter in abnf composition.

The parts dismantled from the CRT monitors are shown in Fig. The alternatives that have been used worldwide to discard sludge from sewage treatment are burning, landfill, land farming, heavy clay ceramic industry and agricultural recycling. WEEE contains a significant number of precious metals, many of which are being recovered through different studies:
