Full Description

The equilibrium adsorption behavior of natural organic matter (NOM) subjected to coagulation and various levels of ozonation and biostabilization was investigated in bench-scale experiments. The overall adsorbability of NOM increased with coagulation but decreased if coagulation was followed by ozonation and biostabilization. Without adsorption, ozonation was shown to enhance the biodegradability of coagulated NOM; up to 46 percent of total organic carbon was removed at the highest ozone dosage. The adsorption of NOM was described quantitatively by accounting for competitive adsorption among pseudocomponents and by applying concepts of polymer adsorption. Neither approach was entirely satisfactory for obtaining a systematic relationship between adsorbability and ozone dosage. Includes 29 references, tables, figures.
