Diseño de una planta de tratamiento de aguas residuales urbanas a escala de laboratorio

Abstract

For future years, the world population will have grown in large proportions and also the negative effects of global warming, cities will suffer from the scarcity of water, but only the issue of quantity is considered, leaving aside the quality and infrastructure needed to its supply or reuse (González de Posada, 2010). Therefore, the present work is focused on the hydraulic design of a treatment plant that improves the quality of wastewater, being essential the construction and monitoring of a pilot plant at laboratory scale to verify the efficiency of it. The study includes: the physical, chemical and microbiological characterization of urban wastewater; the selection of technologies for treatment; the design, scaling, construction and monitoring. Obtaining an 87.36% removal of the real color and organic matter in terms of COD of 79.17%, values that demonstrate the efficiency of the selected treatments and the expected purification values so that the effluent meets the requirements established in the TULSMA 2015 standard of discharges to bodies of fresh water.
