Abstract
Sampling campaigns were conducted for hazardous chemicals and heavy metals in influents and effluents of industrial wastewater treatment plants (WWTPs) in Korea for best management practices (BMPs) of those pollutants through the plants and the receiving water bodies. Twenty seven WWTPs, receiving wastewater from industrial complexes and treating more than $2,000m^3/day$, were selected for the sampling campaign. Influents and effluents of each WWTPs were sampled once a month (total three times per plant) between July and September, 2012, and analyzed for 22 hazardous water pollutants among 28 regulated for effluents limits in Korea. Concentrations of mercury, arsenic, 1,1-dichloroethylene, and benzene in the influents were relatively higher; concentrations of mercury and arsenic in effluents were relatively higher than those of other pollutants. Most of the hazardous chemicals and heavy metals were removed (including phase transfer) more than 60% through the treatment processes except for selenium (30% removal) and 1,4-dioxane (18% removal).
