Estudio de la eficiencia de arcillas como medios filtrantes en la reducción de la turbidez de aguas naturales

Natural water will always be contaminated by natural and anthropogenic activities, that`s why the proposal to innovate treatment methods to decontaminate natural water by means of easily obtained lithological material.This research aims to evaluate the efficiency of reducing the turbidity of natural water using clay beds as filtration media. Five different types of clay (yellow, red, gray, brown, white) were collected in Pastaza Province. For this purpose, the calcined lithological material was prepared and conditioned to form the bed filter. To assemble filters 3 pounds of each clay were weighed where turbidity was taken as a control parameter, in addition to conductivity and pH during the filtering process. In order to compare the efficiency of the beds, four filtration tests were carried out, the first with a new bed to determine the reproducibility, efficiency of the filter after washing, flow effect and a comparison with a sand filter. The results indicate that the five clays decreased turbidity being the filter made with the yellow clay bed which provides the best reduction of the parameter with a value of 6.74 NTU followed by the red clay bed that reduced 9.99 NTU limit permissible for drinking water established by TULSMA. Apart the clay beds are reproducible and regenerable because they maintain and improve their efficiency once used. Checking that they are more effective than a conventional sand and gravel filter.
