Description
Summary:The current research project had as purpose to design a secondary biological system for strengthening the anaerobic wastewater treatment plant from CEASA Campus. The study was developed in three stages: first, it was determined the residual effluent flow rate and contaminant load from the university center; secondly, it was established the appropriate measures for the elements design, what make up the secondary biological system; and, thirdly, it was assessed the proposed design efficiency, through the development and operation a pilot system. It was used a qualitative approach, through direct observation and bibliographic research, further to a quantitative approach, what included the volumetric method application to get flow measurements, as well as the data analysis on physical, chemical and biological parameters from pre- and post-treatment. The information gathering determined an average flow 1.34 m3/day from wastewater, by highlighting an effluent greater generation between 10:00 and 14:00 on Tuesdays and Wednesday’s days. The collected data were the basis for the primary settler sizing, trickling filter and secondary settler. With the calculations results, it was made the pilot plant construction at a 1:10 scale, which demonstrated physicochemical and biological parameters notable efficiency in the reduction measured, such as: fecal coliforms, pH, temperature, total solids and total suspended solids. Further, it was achieved an organic load removal 76.18% for DBO5 and 68.4% for DQO, in comparison to the initial data, improving water quality and complying with the limits established in Table 9 from Ministerial Agreement. 097 A. These results confirm the technical feasibility from secondary biological system to strengthen wastewater treatment on the CEASA campus.
