Abstract

The purpose of this research was to evaluate the efficiency of coffee grind residues with cocoa shell as the basis for a filter to reduce lead from the contaminated water of the Chirino River, San Ignacio - Cajamarca, 2018. Providing a method of low cost and without the use of large-scale technologies, by taking advantage of the organic waste mentioned above, thus improving its final disposal. The experimentation was carried out in a conventional design system, where the placed filter presented a spongy structure containing 60% of coffee borage with cocoa shell applied in three different doses (15g coffee grind with 15 g cocoa shell, 10g coffee grind with 20g cocoa shell and 20g coffee grind with 10 g cocoa shell) and 40% of sugar in silicone elastomer solution; having bioadsorbent properties to reduce metals. The sampling point and the amount of sample in liters was for convenience, evaluating the concentration of Lead present in the water of the river Chírinos in the stages of pre-treatment and post treatment. The results obtained with respect to the efficiency to reduce Lead of the three doses applied coded with T-1, T-2 and T-3 were 77.1%, 98.53% and 87.36% respectively; being the most efficient T-2 contiendo the dose of 10g coffee grind with 20g cocoa shell, without the need to add a chemical activator, making the application friendly with the environment.
