Análisis del Piroclasto Volcánico como filtro en el tratamiento de aguas residuales provenientes de la industria láctea “Aproleq” ubicada en el cantón Quero provincia de Tungurahua

Abstract

The principal objective of the following project is to evaluate the efficiency of the filter material. To carry out the research; a filter was constructed with a filter material (volcanic pyroclastic) that was in operation during a period of 92 days in situ. The size of the container, which kept the material, has a volume of 35 liters of material. The flow rate used for the filtration process is 0.105 l / min that was supplied by a 55-gallon tank, which was supported by a metal structure at a height of 2m and must be completely filled every day. In order to verify the effectiveness of the filter, the analyzes of BOD5, COD were carried out in the environmental services - oil and greases - in the Laboratory of the Civil and Mechanical Engineering Faculty - “Universidad Técnica de Ambato”; the samples were collected under the specifications of the norm NTE INEN 2 169 and 176. The results have shown a decrease in contamination levels in an average percentage of 72.68%, 71.18%, and 78.78% of BOD5, COD, Oil and greases respectively. It is concluded, with the results obtained that the volcanic pyroclastic could be used in the pretreatment of residual waters, due to the characteristics of porosity that it possesses which reflected a high degree of effectiveness.
