There are increased activities in development and application of directly electrolysed water using the natural chloride content for disinfectants production. Free chlorine produced with electrolysis water can be a very useful disinfectant for the removing pathogen microorganism. The present works presents the evaluation of free chlorine generation and THMs characteristics during and after electrolysis. All electrodes were titanuim based insoluble materials and rectangular plate with an effective area of 50 ㎝×20 ㎝. Electrolysis reactor composed of the six negative electrodes and the five positive electrodes. Directly electrolysis reaction using the natural chlorine content in sand filtered water generated the free chlorine for feasible disinfectant. The residual chlorine be generated 1.0 ㎎/L in current density 3.8 A/㎠ and flow 5.0 L/min. the generated free chlorine concentration was stable. Electricity was exponentially increased with flow increment for the chlorine formation. Specific chlorine value which means the generated chlorine rate per current density was 1.60 at the flow of 15 L/min. Chlorine concentration of 1 ㎎/L was stably generated above 1.0 current density and below 30 sec retention time for chlorination concentration of 1 ㎎/L. The by-products generated by high concentration residual chlorine in the reactor such as trihalomethanes were detected in less than a water quality standards.
