Removal efficiency and homologue patterns of dioxins in drinking water treatment

Polychlorinated Dibenzo-p-dioxins (PCDDs) and Dibenzofurans (PCDFs) and Polychlorinated Biphenyls (PCBs) in Water Samples from the Middle Reaches of the Yangtze River, China

“…The concentration ranges of total PCBs in drinking water from Japan (Kim et al 2002) were comparable to those in this study. Kumar et al (2012) reported that total dl-PCB concentrations were higher in surface water from various sources in India than those found in this study.…”

“…The concentrations of P PCDD/Fs in the Yangtze River ranged from 0.6 to 6.8 pg/L (Table 1) which were comparable with those reported for ground water in Japan (Kim et al 2002). The P PCDD/Fs concentrations in samples collected from industrialized areas such as the River Kanzaki (Kishida 2013) were more than ten times higher than those from this study.…”

Refractory organic pollutants and toxicity in pulp and paper mill wastewaters

“…Even though dioxins and furans have low solubility in water, they have been found in aquatic environment mainly from atmospheric deposition but also from sewage treatment plants (Kim et al 2002). Dioxins can be removed by e.g.…”

Dry and Wet Deposition of Polychlorinated Dibenzo-p-dioxins and Dibenzofurans on the Drinking Water Treatment Plant

“…If the deposition was not removed by the treatment units, it will increase the PCDD/F concentration in water up to 8.91 × 10 -3 pg I-TEQ/L, which is about 92% of PCDD/Fs in raw water. Kim et al (2002) reported that the majority of PCDD/F mass are well removed (removal efficiency 87%) by conventional rapid sand filtration, thus the treated water may increase 1.16 × 10 -3 pg I-TEQ/L, which is about 43% of the level in tap water. The above results indicate that the influence of atmospheric deposition of PCDD/Fs on drinking water is of great significance and the water treatment facility with a cover is suggested.…”
