Diagnostico y optimización de laplanta de tratamiento de agua potable del municipio de Combita Boyacá

Abstract

The municipality of Combita has an aqueduct system that supplies the service mainly to the urban area of ​​the municipality, this system is composed of two sources of surface supply and one underground, in addition to having a drinking water treatment plant since 2007 Throughout its operation, the plant has presented latest variations in its IRCA, which has presented a value in the 7 years that ranges between 7.29 and 13.3, except for the immediately previous year, which had a value of 2.23, which may show shortcomings in the processes carried out in the treatment plant. That is why this work made a diagnosis of the conditions and current operation of the Plant in the municipality of Combita Boyacá, through a comparison of the main design criteria of the Plant units with the values ​​recommended by the applicable literature. , apart from the verification of the IRCA reported by the Boyacá health secretary in the most recent years such as 2012 and 2013, in order to identify which parameters are not complying with the provisions of current Colombian regulations (resolution 2115 of 2007 and the Decree 1575 of 2007, also presents the verification of the current status of the units of the pathologies found. Likewise, effluent treatability tests were carried out with coagulants such as aluminum sulfate, ferric chloride and ferrous sulfate at different concentrations, accompanied by caustic soda or lime. The above will determine the doses that developed a better coagulation, flocculation, sedimentation and filtration process at the end of the process was the dose of 40 mg / L of aluminum sulfate accompanied by 15 mg / L of hydrated lime, this dose yielded a removal of the 94.2% turbidity, with a pH of 6.68, conductivity 64.7 s. Total Dissolved Solids 38.9 mg / L and a value of or mg / L of iron.
