Diseño e implementación de una planta de tratamiento de aguas residuales en la Planta de Producción La Madrileña de Latacunga.

Abstract

A Wastewater Treatment Plant for the production Company “La Madrileña de Latacunga” was designed and built to give treatment to the wastewater generated during the production process before being discharged into the Cutuchi River. Physical – chemical and microbiological analysis were conducted to wastewater performed in the CESSTA laboratory, obtaining data of various that revealed the quality of wastewater generated in the plant and according to which it was proceeded to perform engineering calculations for sizing the treatment plant. Taking as reference the data obtained we selected the type of treatment for the effluent, the same consisting of various operations such as: a homogenizer tank in which Aluminum Sulfate Al3(SO4) is added to flocculate the residual matter in the water and to be easily separated, a setting tank in which the flocculated water is decanted by gravity and fats and oils are retained in positioned plates inside the tank, 2 gravel filter, anthracite and activated charcoal where odors and particles that were not retained in the above process are finally retained and a disinfecting tank in which chlorine is added to kill microorganisms. The treatment plant was subjected to a test before final start to determine its efficiency, once wastewater was treated characterization of it was performed and managed to establish water quality within the parameters required by UTSEL (TULAS). When comparing these values with those obtained initially it was demonstrated that treatment plant built has an average efficiency of 78,9%. It is concluded, from the performed analysis of treated water and the efficiency obtained, that the treatment plant was designed properly, achieving meet the stated objective, which is to discharge to Cutuchi River treated water to avoid pollution of this, preventing ecosystem degradation and in compliance with the parameters of the environmental laws.
