Análisis del ladrillo triturado como filtro en el tratamiento de aguas residuales provenientes de la fábrica de lácteos “El Ranchito” ubicada en la ciudad de Salcedo

Abstract

In the present investigation a filter with crushed brick was made as a filtering material, with the purpose of reducing the contamination coming from the residual water of a dairy industry, for which we proceeded to characterize and monitor the same at the beginning and end of the filtration process, taking into account the physical-chemical analysis of the parameters such as: Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD) and Oils and fats. The filter remained operational for 90 days (three months), at which time periodic samples of filtered water were taken every ten days or so, obtaining an amount of nine samples of filtered water and a sample of unfiltered (raw) water. They were transported to an accredited laboratory for their respective analysis in the aforementioned parameters. Once obtained the results of the analyzes carried out in the laboratory, the efficiency of the filter was determined, comparing with the results of the analysis carried out on raw water. In addition, it was verified if the values obtained comply with what is stipulated in the Unified Legislation of Secondary Legislation of the Ministry of the Environment (TULSMA) for wastewater that is expelled to the public sewage network. With the results obtained it was determined that the crushed brick acting as filtering material if it reduces in a large percentage the values of the aforementioned parameters.
