SUMMARY:

This research aims to produce elements for evaluating the feasibility of adding new technologies to a sanitary sewage treatment plant using the activated sludge process. The study is carried out in full scale at ETE Itatinga, located in the city of São Sebastião in the State of São Paulo. The research is divided into two stages. The first is the biological removal of nitrogen via simultaneous nitrification/denitrification, controlling the age of the sludge and the air supply system by sensors of dissolved oxygen, ammonia and nitrate concentration, and of redox potential installed in the tanks. of aeration. In the process control, determinations of rapidly biodegradable COD, total Kjeldahl nitrogen, ammonia, nitrite and nitrate in the sewage and SSV, densities of nitritating, nitrating and denitrifying bacteria, among other variables, were included. This study is expected to contribute to the development of a differentiated form of operational control that leads to energy savings for aeration and that results in the important benefit of nitrogen removal from sewage. The second stage of the research consists of lateral flow biological phosphorus removal coupled with simultaneous nitrification and denitrification (NDSRP). This study is expected to evaluate the alternation conditions necessary for the removal of nitrogen and phosphorus and the main operational conditions for the possibility of simultaneous nitrification, denitrification and phosphorus removal in a single biological system. This alternative has shown promise in studies in Europe to face the usual challenges of conventional phosphorus removal processes.
