Diseño de un sistema de tratamiento de aguas para la recirculación en los procesos industriales de la Hormigonera de los Andes, provincia Chimborazo.

Abstract

A desígn of a water treatment system was held for recirculation in industrial processes of "Hormigonera de los Andes" in order to reduce the impact and optimize resources generated within the company. A simple sampling collecting three samples of wastewater for a period of two weeks was conducted, samples were taken at the unloading truckloads of concrete, then these samples were taken to the testing laboratory of the Faculty of Technical Sciences ESPOCH in order to perform the respective physico-chemical analysis determining the parameters outside the permissible limits based on the Standard NTE ENEN 2617:2012 hydraulic concrete. Water for mixture. Requirements. In the physico- chemical characterization of samples collected standardized methods were used: standard methods and HACH method by which two physicochemical parameters outside the permissible limits were identified: chlorides and total solids. To reduce the parameters outside of standard engineering calculations by which the following components were si/ed were made: rectangular clarifier 5.04 m 3 , filtration tank 2,87m 3 and drying beds 2,70m 3 . To verify the quality of the concrete mixtures were made with the treated water and the water tanker in different proportions, with which concrete cylinders of 210 kg/cm 2 were developed, obtained with the mixture of 50%, a percentage of resistance to 7 days of 93.58 %. Thus for the recirculation of treated water in the process it is recommended to use 50% of treated water from this research and the other 50 % must be filled with regularly water engaged in the manufacture of concrete in order not to alter the final product quality.
