PURPOSE: To promptly respond to the change in the water quality of raw water, automate an apparatus and enhance the reliability of the apparatus by optimizing a chemical injection ratio necessary to get an objective flock particle diameter to obtain good water quality. ;CONSTITUTION: An apparatus is equipped with, besides an agitation vessel 8, a quantitative raw water supply part 9, an agitator 10, a pH control part 11, a water discharge part 12, a measuring part 13, and a coagulant injection part 14 as main units. The raw water supply part 9 and the agitation vessel 8 are connected by a raw water supply pipe 17, in which an alkli injection port 17a and a chemical injection port 17b are formed. The size of flocks produced in the agitation vessel 8 is measured by the measuring part 13, and the data are output to a computer 24 to be compared with a preset particle diameter. A coagulant is sent to the quantitative injection pump of the coagulant injection part 14 and injected from the chemical injection port 17b of the raw water supply pipe 17. The rotation speed is output to the agitator 10.;COPYRIGHT: (C)1995,JPO
