Also, the feedback control system utilized in the past, operating with fixed residence time, showed the limit of automatic operation because it was unable to appropriately respond to the change of water filtration quantities, which resulted in exceeding standard for the K-water water quality Accordingly, proposing a disinfection process control system that automatically calculates the residence time from water filtration quantities, after comparing the data from injection rate operation, it has been verified that there is more than 1.5 Times improvement in direction of the target outflow concentration.
