영문 초록

In this study. chlorine dose at water storage tank was predicted to meet the recommended guideline for free chlorine residual in drinking water distribution system. using EPANET which is a computer program that performs extended period simulation of hydraulic and water quality behavior within pressurized pipe networks. The results may be summarized as follows. The decay of chlorine residual by season varied considerably in the following order: in summer (25℃) > spring and fall (15℃) > winter (5℃). For re-chlorination at water storage tank by season. season-varying chlorine dose was required at its maximum of 1.00 mgll in summer and minimum of 0.40 mgll in winter as free chlorine residual. The decay of chlorine residual through out the networks increased with water age spent by a parcel of water in the network except for some points with low water demand. In conclusion. the season-varying chlorine dose as well as the monitoring of water quality parameters at the some points which showed high decay of chlorine residual may be necessary to deliver the safe drinking water.
