Measurement of Color, Turbidity, Hardness, and Silica in Industrial Waters


The quality of water is of daily concern to most chemical companies, because product quality is often dependent on water quality. Continuous analysis should permit realization of the close control needed. Accepted laboratory methods for measuring color, turbidity, hardness, and silica in industrial waters are reviewed with particular emphasis on those which offer greatest promise for continuous analysis application. Standards for color and turbidity are also discussed.
