Análisis de la cascarilla de arroz utilizada como material para filtros de tratamiento de aguas residuales provenientes de la lavadora de jeans “Multiprocesos Gallegos”

Abstract

In the present experimental project, a rice husk filter prototype is being developed for the treatment of wastewater from the "Multiprocesos Gallegos" jeans washing company, located in Pelileo canton, Tungurahua province. The process of sample collection is addressed to be analyzed; raw water is considered to be taken before the filtration process and filtered after the filtration process. The duration and operation of the filter was three weeks, taking two samples each week during the days of highest production. The chemical parameters considered for the analysis were BOD5, COD and color. The collected samples were analyzed in the Lacquanalisis certified laboratory located in Canton Ambato, province of Tungurahua. To have more accurate results, the samples were taken on the same time and transported in a coolant to the laboratory. In the same way, taking raw and filtered samples gives a real appreciation of the results obtained. The results obtained during the three weeks reflect the behavior of the filter and its effectiveness against the parameters evaluated. As a final result it can be evidenced that the filter decreases the values of BOD5, COD and color always considering the Discharge Limits to the Public Sewer System.
