Knowing the impact on health associated with the organic arsenic through drinking water in southern Peru, the present study seeks to contribute to removal this metalloid in a sustainable way and compatible with the conditions of access to supplies and resources that currently exist in the area. Among the arsenic abatement methodologies, the conventional technology was selected and the objective was to find the best combination of coagulant-flocculant both in type and in dosage for which it was established that the scope of this thesis is applied, quantitative and experimental. The development of the present investigation was based on the realization of multiple trials via Jar-Test through an inductive methodology that was carried out through the following steps: A) characterization of the water of the Uchusuma creek located in the department of Tacna B) Jar - Tests' of selection of coagulants and flocculants. C) Establishment of optimal doses. D) Confirmatory tests. Of the flocculants tested Ferric Chloride was selected because it showed the best performance in As removal, with optimal doses between 34 and 40 ppm; Likewise, we selected as the best flocculant a cationic polymer with an optimum dose between 0.30 and 0.40. A cost estimation analysis was carried out, finding that for high consumption potabilization systems the unit cost would oscillate between 0.022 and 0.026 $ / m3, while for small mining projects the unit cost can range between 0.055 and 0.068 $ / m3.
