What is it about?
The Federal District (DF) of Brazil has 16 Sewage Treatment Plants (STPs) in operation, which employ diversified treatment technologies and generate around 300 tons of sludge daily. The present research aimed at characterizing the processes of production and treatment and the quality of the sewage sludge generated in the STPs of the Federal District to identify viable final disposal alternatives. The sludge production coefficients were verified and compared with the literature, and it was difficult to establish a sludge generation standard for the primary treatment phase. The necessary requirements for the management of the sludge were raised, and with the sludge produced by the STPs of the Federal District characterization, a scenario was created with alternatives that favor the reclamation of sludge. It was concluded that a simple and low-cost complementary treatment for sludge sanitation would allow its adaptation to agricultural use.
