Modelación y optimización del reactor biológico de membrana de la planta de tratamiento de agua residual de la Ciudad de Tena

Abstract

This research aimed to increase the removal of chemical oxygen demand from suspended solids and ammoniacal nitrogen from the biological membrane reactor of the Wastewater Treatment Plant of the Tereré neighbourhood of the city of Tena, located in the province of Napo. The baseline survey of the current operation of the WWTP was carried out, in which it was determined that the removal of organic matter was 60%, for which first the management of the student license of the WEST lab kit software specific for wastewater modelling. In the second part, the amount of dissolved oxygen, the hydraulic retention time and the amount of biomass, which are the variables that directly affect the operation of the biological reactor, were determined. To carry out the simulations, the oxygen concentration was taken into account. For all scenarios, some variables were Kept constant, with a ninety per cent removal of organic matter as a global result.

An analysis of the best alternatives for optimization was also carried out, which was applied in the actual situation of the Water Treatment Plant residual, where a better removal of organic matter was obtained, surpassing what was obtained in the simulation. As a final point, the proposal was validated by comparing the results of discharge into the river in Table 10 of the TULSMA, ratifying compliance with the Environmental Legal Regulations in all the results. Simulating the sludge line of the Water Treatment Plant Residual of the city of Tena is advisable.
