Desarrollo de un sistema de filtración para la remoción de dureza del agua en la empresa COSMOGREEN S.A.S Cúcuta- Norte de Santander.

Abstract

This project aims to improve the filtration system at Cosmogreen S.A.S, located in the city of Cúcuta, Norte de Santander, in order to remove water hardness. The company captures the water resource, from an underground well that has a very high hardness quality and does not conform to the parameters for the preparation of detergents. The constant filtering system of 3 ion exchange filters composed of cationic resin in series regenerated with brine, but the process that was successful in the company failed to adjust the hardness of the water to the quality conditions for the process. Therefore, for the achievement of the project, the evaluation of the series filtering system was carried out, by means of physicochemical analysis, of total hardness, suspended solids, pH, conductivity, turbidity, biochemical oxygen demand and exchange capacities, considering two systems of filtering that helps the system in series filtering. The first system proposed consists of a pre-filtration with variations of lime, where the optimum concentration is determined by evaluating the physicochemical properties of hardness, suspended solids, pH, conductivity and turbidity, after concentration. The second filtering system, the position of the filters is varied in parallel, working individually to improve the filtration times, evaluating the physicochemical properties of the water and establishing the capacity, the filtering times and the regeneration time are also determined, directly as the optimal concentration of the regenerant. With the implementation of the prefiltering system, water hardness could be reduced by 39%, being a viable solution to help the filtration system, in case a larger volume of filtering is required, for the second filtration system it was possible to increase water production from 6000 L to 15000 L Quality problems required by the company. Likewise, the regeneration system was improved by reducing the washing time of each filter by 68%. In addition, the registration volumes are adjusted, reducing the salt used for the regeneration of the filters by 28%, being a considerable improvement for the company's economy.
