Abstract
PURPOSE: To perform the treatment of water effectively by saving chemical by the procedure in which a slow-speed stirred basin and a sedimentation basin are bypassed at the time when the turbidity of original water in a water purification plant is low and then introduced from a high-speed stirred basin directly to a filtration basin and at the same time the amount of chemical to add is controlled to a minimum.
CONSTITUTION: Original water injected with a coagulant in the high-speed stirred basin 2 is usually treated at the slow-speed stirred basin 3 to form flocs, sent to the sedimentation basin 4 to precipitate and remove the flocs, and then introduced into the filtration basin 5. And, at the time when the trubidity of original water is low, it is detected by the turbidity detection circuit 13 in the slow-speed stirred bypass controller 12 and then original water injected with coagulant at the high-speed stirred basin 2 is introduced into the filtration basin 5 and then filtered in the state of containing the nuclei of floas. At the same time, a bypass signal is sent to the chemical control panel 7 and also a command to alter the setting for the chemical to be injected to a limit amount necessary for forming the floc, are given.
