Abstract

PURPOSE: To indicate whether or not parameters relating to turbidity of treated water in a water purification plant, such as alkalinity of water flowing into agitation pond, pH of coagulated water, and alkalinity of coagulated water, exceed specified values.
CONSTITUTION: Raw water is treated while passing through a water inlet well 1, an agitation pond 2, a flock formation pond 3, and a settling pond 4. Between the water inlet well 1 and the agitation pond 2, an alkaline agent 6 is injected, and corrected alkalinity, pH of coagulated water, and alkalinity of coagulated water are set to exceed specified values so that the effect of a coagulant 8 can be fully developed. At this time, three parameters of alkalinity 13 of water flowing into the agitation pond, coagulated water pH 9, and coagulated water alkalinity 10 are compared with each of the specified values. The values exceeding the specified values are displayed on CRT screen in different colors. When two or more parameters exceed the specified values, the parameter significantly exceeding the specified value is indicated in larger form.
