| description | In this paper the electrolytic process application as a water purification treatment stage from the Ipê neighborhood lake (Ilha Solteira –São Paulo, Brazil–) was evaluated. The treatment efficiency for apparent and true color removal, in samples by addition of humic substances, to reach different colors levels was determined. It was monitored the 1 g/L NaCl and TiO2 addition individual effect. The removal efficiency for each trial in samples taken from the electrolytic reactor each 10 minutes during one hour, were calculated.For the water sample with initial apparent color of 25 Hu, it was reduced up to 15 Hu –maximum permitted value according the Brazilian drinking water guidelines– after 30 reaction minutes. For the apparent water color with 66 Hu, with sodium chloride addition, a reduction up to 13 Hu was measured after one hour reaction. In the trials with humic substances addition, the apparent color removal for water with 708 and 247 Hu, were 87.3 % and 84.2 %, respectively, after 60 minutes of reaction.The results showed the electrolytic process performance with use of salts as a drinking water treatment stage, both for the apparent color reduction below the maximum permitted values defined by the legislation, as for its removal up to certain levels, treatment stage that should be complemented by additional stages. |

Se evaluó el proceso electrolítico como etapa de tratamiento para la potabilización de agua del lago del barrio Ipê (Ilha Solteira –São Paulo, Brasil–). Se determinó la eficiencia del tratamiento para la remoción de color aparente y verdadero sobre muestras a las que se adicionaron sustancias húmicas para alcanzar diversos niveles de color. Se evaluó el efecto individual de la adición de 1 g/L de NaCl y de TiO2. Para cada ensayo se calculó la eficiencia de remoción a partir de muestras tomadas del reactor electrolítico en intervalos de 10 minutos durante una hora. Para agua con color aparente inicial de 25 uH se redujo hasta 15uH –nivel máximo permitido por la norma brasilera de agua potable– en 30 minutos de reacción, para agua con 66 uH de color aparente, con adición de sal, se redujo hasta 13 uH en el término de una hora. En los ensayos con adición de sustancias húmicas, la remoción de color aparente para agua con 708 y 247 uH fue, respectivamente, de 87.3 y 84.2 % después de 60 minutos de reacción. Los resultados mostraron el desempeño del tratamiento electrolítico con uso de sales como etapa de potabilización del agua, tanto para alcanzar los niveles de color aparente establecidos por la legislación, como para su remoción hasta ciertos niveles, etapa de tratamiento que ha de ser complementada por otras posteriores.
