ABSTRACT:
A method and apparatus for controlling the feed rate of water treatment chemicals to a process stream requiring such treatment. A sample stream is obtained from the dynamic process stream at a controlled and constant rate and is fed to a settling column. The settling column is equipped with underflow and overflow weirs and a sensor between the weirs for monitoring the concentration of solids. The settling column provides a quiescent area in which solids and/or other particulate matter to be settled can demonstrate their relative tendency to do so. A controller responsive to the sensor governs the feed rate of a particular treatment chemical.
