Diseño de un Filtro con Piroclastos Finos para la Purificación del Agua de la Comunidad de San Francisco (Baños - Tungurahua)

Abstract

"This work deals with the design of a filter using pyroclasts with a size lower than 2 cm from the Volcano Tungurahua, to improve the water quality from the spring of the community San Francisco.

Filtration trials were carried out at a lab level in an 9 L tank, packing the filtering material at different heights S, 10 and 15 cm. Two exit volumes of the filter (Q1=0,32 and Q2=0,04) were determined at different valve openings for its adjusting.

lt was determined that the pyroclast used permitted a considerable decrease in the quantity of solids suspended ín the spring water, with 55% efficiency improving the mater quality as related to the unfiltered water.

lt is concluded that the water from the spring san Francisco not only requires a filter of pyroclasts but also the implementation of a sand chamber before the filter and finally a chemical process such as chlorating so that it mat be suitable for human consumption."
