Evaluación de microorganismos eficaces para el tratamiento de agua residual de Grupo Rossi.

Abstract

This work was carried out at the Rossi Group Company, located on the Panamericana Highway via Machachi, whose objective is the evaluation of effective microorganisms for the treatment of wastewater, to reduce the load of pollutants, so that they are under the TULSMA regulations. As a first step, the characterization of the wastewater was reviewed and it was determined that the effluent is biodegradable, therefore a biological treatment is very useful in this case. Subsequently, a laboratory-scale prototype was built for its treatment, where 10 L of wastewater was treated, and concentrations of Efficient Microorganisms (EM) were set at 2% and 5%, with the implementation of an aeration system to compare the results of the treatment with the different concentrations of EM. At the end of the treatment after 10 days, an improvement in the quality of the wastewater was observed, with which the parameters such as COD, BOD and some nutrients complied with the regulations for discharges to the sewage system. Finally, the MS treatment was compared with a worm filter treatment, to highlight some advantages and disadvantages of the treatments used.
