Removal of pharmaceuticals in conventional drinking water treatment processes

Abstract

“Antibiotics are used as a feed additive to promote livestock production. In the United States, there are roughly 2.5 million kilograms of antibiotics used for livestock production each year. There has been increasing public concern, however, that this widespread antibiotic use may lead to contamination of the ground and surface water. This contamination risk increases the potential for the creation of antibiotic-resistant bacteria that could pose a risk to human health.

In this paper, seven antibiotics: carbadox (CARB), sulfamerazine (SMRZ), sulfamethazine (SMZN), sulfadimethoxine (SDMX), sulfathiazole (STZL), sulfachlorpyradazine (SCPD) and trimethoprim (TRMP) were chosen for study of pharmaceutical water removal. Alum coagulation, iron coagulation, lime softening, powdered activated carbon (PAC) sorption, chlorination, ultraviolet (UV), ozonation, ion exchange, and reverse osmosis (RO) were used for treating antibiotics.

The results showed that alum coagulation, iron coagulation, lime softening, UV photolysis and ion exchange methods were determined to be ineffective for treating antibiotics. However, PAC, chlorination, ozonation and RO were more effective, and could attain 90 percent removal of pharmaceuticals. Chlorination of pharmaceuticals created oxidation byproducts detected by HPLC/UV. Identification of the identity and properties of these byproducts were beyond the scope of this study. The further research should focus on PAC, chlorination and ozonation methods"--Abstract, page iv.
