Evaluación de la viabilidad de uso de los lodos de la planta de tratamiento de aguas residuales del cantón Francisco de Orellana, provincia de Orellana, en la elaboración de adoquines de construcción

Abstract

The purpose of the project was to evaluate the feasibility of using sludge from the wastewater treatment plant of the Francisco de Orellana canton in the elaboration of construction paving stones. The sludge is intended to be used in the construction field as a new viable method, in addition, it is intended to minimize the impact it generates on the environment. The sludge, once sampled, was analyzed in the laboratory of the Provincial Council of Orellana (GADPO). Later, the sludge was used in the elaboration of paving stones, with the collaboration of the DekoPiso micro-company. The paving stones, once manufactured, went through a curing stage for 28 days, to then carry out compression tests in the city of Quito, in the LEMSUR laboratory, where the paving stone breaks were made to measure its resistance. The paving stones were prepared for leachate analysis by immersing them in distilled water and they remained for 30 days, later samples of the leachate were taken and taken to be analyzed in the AqLab laboratory in the province of Orellana. Finally, an evaluation of the paving stones was prepared, where products that meet the mechanical and environmental requirements were obtained, with which a future reproduction of the paving stones is expected.
