    Evaluación de la planta de tratamiento de aguas residuales de la parroquia Poatug, cantón Patate, provincia de Tungurahua

    In the present experimental project, the Evaluation of the Wastewater Treatment Plant (WWTP) located in Poatug Parish of the Patate City in Tungurahua province was carried out with the objective of verify whether it is fulfilling the purpose for which it was built properly. The evaluation of the WWTP of the Poatug Parish began with a research of information of the WWTP of this current state. The flow of residual water is determined both at the entrance and at the exit of the WWTP and the important hours in which greater and lesser amount of residual water enters the WWTP during the day. In addition, a sample of the wastewater from the WWTP was conducted, which was analyzed in a certify laboratory in order to determine the contaminant load that is treated in the plant and compare with the parameters for wastewater discharges in rivers established in the TULSMA 2015. The current treatment process was evaluated (primary sedimentation, septic tank, Anaerobic Upstream Flow Filter and sludge drying bed) used to remove contaminants present in the incoming wastewater and it is found that it only removes approximately 40% of contaminants, which indicated that the WWTP is not working properly. On the other hand, it was found that several of its hydraulic structures are not maintained with the parameters established in the design manuals of the treatment plants. Finally, it is proposed to incorporate a new treatment process (inlet box, screening, sand trap, Anaerobic Upstream Flow Filter and sludge drying bed) so that the wastewater treated in the WWTP theoretically removes about 90% of the contaminants in an efficient way. On the other hand, an Operation and Maintenance Plan proposed so that the WWTP will have a proper functioning.
