Stoichiometric Relationship Between Humic and Fulvic Acids and Flocculants
The investigation of the flocculation of humic and fulvic acids has shown that the sodium salts of these acids, which are anionic polyelectrolytes, react chemically with the flocculants, such as cationic polyelectrolytes, and aluminum sulfate through carboxylate and phenolate groups. A stoichiometric relationship has been found between humic and fulvic acids content in solution and the cationic polyelectrolyte or alum dose required for effective flocculation of the humic substances. As the pH value becomes lower, flocculation is better; the degree of dissociation of the organic molecule is lower, and the flocculant requirement is lower.
