Abstract

PURPOSE: To provide a novel chemical injection device in a purification plant. wherein the injection ratio of a coalescing agent is selected in consideration of the hourly varying spead of the turbidity of crude water, whereby excellent coalescing and settling effects can be obtained with respect to the rapid variation of the turbidity of crude water.
