Diseño y construcción de un sistema de reutilización del agua en la mezcla del hormigón

Abstract

Nowadays the people are considering the environmental care and especially applying the practices of the good one to live, allowing to take care this way of our planet. In case of the Metropolitan District of Quito, the municipal ordinance is in force 213, where one of his chapters treats on the protection of the hydrographic basins. By means of this parameter the companies have the obligation to treat the waters that are in use in industrial processes for eliminating them for the sewer, or if it is possible to recycle it in processes that the company arranges. The civil construction in these days has increased in an exuberant way, is for such reason that the cement mixer industry also has grown for the whole capital to supply to the civil work. Reason for the entities of follow-up granted by the city hall of Quito, they realize environmental audits to these companies and to notice that they realize a correct fulfillment of what dictates the law of environment. One of the principal points, that was mentioned previously, is to give a better managing to the water. In the cement mixers, one of the principal resources in the production of the concrete is the water, the drinkable liquid in the course of the mixture of other raw materials that will give us like result; the concrete is wasted in big quantities. It is for this reason that the Cement mixer J.C.Valenzuela CIA. LTDA., implements a system that allows to re-use the water contaminated in processes of production of concrete and this way to help to the environmental care. For this, we make physicist - chemist studies of the water that become contaminated in the process of the production of concrete and by means of these results the best options are analyzed to be able to re-use the above mentioned water in the production processes. I develop a system that consist of two serial filters, that it leaches the contaminated water caught in cisterns, the same one is propelled by a hydraulic bomb of 1 HP and led by normalized pipeline. The first filter is shaped by a diffuser and a felt of fabric, this filter takes care of retaining the solid particles that they find in the water. In the second filter composed by sand, gravel and activated coal, it takes care of retaining the hydrocarbons and bacteria found in the water of cistern, besides this, here the level of pH diminishes, fulfilling an important role the activated coal that is the one that takes charge giving this property to the treated water, allowing with this to return to use it for the production of concrete. The results show the functionality of this investigation that there reduces the parameters physicist - chemist of the contaminated water compared after happening for the constructed system it is possible to use it without any risk in the production of the cement mixer.
