Removal of Model Organic Precursors by Coagulation

Abstract

Low-molecular-weight organics, i.e., phloroglucinol (P), resorcinol (R), and p-hydroxybenzoic acid (PHBA), were selected as the target compounds to evaluate their removal and precursor reduction efficiency by coagulation under the presence of high-molecular-weight compounds. The results of this investigation reveal that turbidity removal efficiencies can achieve 95% and above, but the total organic carbon removal for P, R, and PHBA are not remarkable, which are less than 20%.
