Comparison of solar distillers for the obtaining of fresh water in wells of brackish water in the Peasant Community San Juan Bautista of Catacaos – Piura

Abstract

Existing the need to obtain fresh water for human consumption for the benefit of
livestock associations located within the boundaries of the Sechura desert and the San
Juan Bautista de Catacaos Peasant Community, in Piura, an experimental scientific study
was carried out with the main objective compare different models of solar distillers,
for at least 3 months, using brackish water from the artisanal well of farmers in the
Tabanco sector. (with a 95% confidence interval) In order to determine the design of
the best suitable freshwater solar distiller, from the point of view, environmental and
economic, the research applied the Bifactorial statistical model of Random Blocks and
did the analysis of variance that was complemented with the Tukey test; obtaining
as a result that the solar distiller of two slopes is the most suitable design for the
environmental conditions of the northern desert allowing a production of 1,509 to
1,767 liters of water per day/m2 of water mirror, for the evaluation period of the
months of November to December, it is also the most economical, with a lower cost
of 34.1 soles over a 10-year horizon to have 20 liters of distilled water per day
