Optimización de la Electrogeneración de Oxidantes Mixtos en la planta de potabilización Rio Nima
(Universidad Santiago de Cali, 2022-07-09) García Zúñiga, Jaime; Castro, Sandra Patricia
The study of causes and effects of parameters affecting the electrogeneration of mixed oxidants (MOS) in an aqueduct is presented. Variables such as inlet water quality, brine concentration, brine pump voltage and current at constant cell temperature and voltage were the object of intervention. By homogenizing and standardizing the minimum brine saturation concentration that feeds the process to 31.7% through monitoring of correlating variables such as density and refractometry, MOS production was increased to concentrations higher than 4800 mg/L with low variation percentages of 2.7%, reducing salt consumption costs by more than 19 million COP per year and contributing to the operational organizational culture of the process. The automation of the electrogeneration and storage of MOS allows for suitable dosing of chlorination in the potabilization of water, guaranteeing IRCA risk scores of 0%.
