DISINFECTION OF WATER FOR HUMAN CONSUMPTION THROUGH THE USE OF A CLAY AND COLLOIDAL SILVER FILTER IN URBAN SECTOR OF LURIGANCHO-CHOSICA

Abstract

The importance of disinfection of drinking water is essential to prevent outbreaks of infectious and parasitic diseases. One method commonly used to purify water is by applying clay filters, the use of which is common in areas devoid of drinking water networks. In consideration of this, the objective of this research was to evaluate the disinfection of water in a sector of Carapongo (Lurigancho-Chosica) with the use of a clay filter with sawdust and colloidal silver. Prototype clay filter models of different sizes were made with 50% sawdust, then colloidal silver was added. In total, 5 filters of different sizes and thicknesses were designed, using 3 of them ceramic clay and 2 natural clay; after the molding of the filters, they were taken at high temperatures to form microporous membranes that fulfill the function of filters, to increase the filtration power, a colloidal silver solution was impregnated, the latter to inhibit the passage of bacteria. The experiment complied with the process of disinfection, purification and removal. The results of the analyzed water samples were compared with the environmental quality standards and the statistical analyzes showed favorable results in both the physical, chemical and bacteriological parameters, and showed that the filter improved the temperature by 2 ° C, favored the increase pH in 0.15 units, helped to reduce from 1979.44 to 1333.55 mg / L the Total Dissolved Solids (decreasing the turbidity level of the water), and the total coliforms and Escherichia coli (EC); The results show that the treatment method is effective, low cost and easy accessibility for housing.
