Coagulation of Organic Color With Hydrolyzing Coagulants
This study investigated the coagulation of organic color using humic substances that were isolated from river water and separated into an acid insoluble (humic) fraction and an acid soluble (fulvic) fraction. The objective was to compare the behavior of the two fractions; a previous study indicated that differences in the properties of organic color in different waters were probably due more to the variations in the proportions of these fractions than to the properties of the individual fractions. Coagulation tests were made at different pH values on solutions of known ionic composition containing different concentrations of humic and fulvic acids. The coagulation method consisted of adding a calculated quantity of a suitable acid to the coagulant so that the total addition of acid equivalents was constant.
