Diseño y construcción de un equipo de filtración del agua en el río Warintz, destinado al uso residencial en el tramo de Yawi y Warintza, mediante un filtro con nanopartículas de cobre

Abstract

Due to the lack of water distribution networks for communities in Eastern Ecuador, they take advantage of the nearby rivers to supply themselves with vital liquid, which is not filtered before being used in the home, causing diseases in its inhabitants, which is why it was designed and built equipment capable of extracting and filtering water from the Warintz River in the Yawi – Warintza section, based on the water quality results obtained by (Otavalo 2022), who applied the ICA-NSF obtaining a medium level water quality. , there were 2 parameters that did not comply with ministerial agreement 97A, which governs the quality criteria of water for human and domestic consumption in Ecuador, these were BOD and fecal coliforms, which were reduced to values accepted as safe, It also verified that other parameters not evaluated in the ICA-NSF are not outside the established ranges. The equipment can supply a flow rate of 5.5 l/min, thus having a waiting time of 3.24 minutes to provide 18 liters to a family of 6 people. Furthermore, the equipment is easy to transport and is designed with energy independence of two hours a day for two days, it has a solar panel, a battery, a charge control, a bilge pump, and three 3D printed filter cartridges connected in series, where two of them, the first and third cartridges respectively, they are filled only with activated carbon of 8X30 mesh size while the second, in addition to being composed of activated carbon, in the middle of the cartridge a sponge was placed with 3 ml of dilution of copper nanoparticles with a concentration of 20% in 100 ml, thus obtaining safe, filtered water for residential use.
