Pilot-scale removal of organic micropollutants and natural organic matter from drinking water using ozonation followed by granular activated carbon

Abstract

Conventional drinking water treatment is inefficient in removing a large fraction of known organic micropollutants (OMPs). Ozonation in combination with granular activated carbon is a promising approach for addressing this issue.

Treatment Trends and Combined Methods in Removing Pharmaceuticals and Personal Care Products from Wastewater—A Review

“…For these reasons, a post-treatment of adsorption is added after ozonation to treat the remaining NOM, PPCPs and their by-products. Many investigations have used AC for this purpose [ 34 , 83 , 84 , 85 ].…”

Long-Distance Transport of Per- and Polyfluoroalkyl Substances (Pfas) in a Swedish Drinking Water Aquifer

“…Thus, the inflow of PFAS into Lake Mälaren is considerable. Detection of PFAS at a drinking water treatment plant using raw water from Lake Mälaren, which supplies Stockholm with drinking water, has recently been reported (Tröger et al, 2018;Ullberg et al, 2021). Although ∑ 11 PFAS concentrations at Stockholm's drinking raw water were relatively low (7.4 ng L − 1 ), removal efficiencies of PFAS at Stockholm's drinking water treatment plant were low (<10%) and higher ∑ 11 PFAS concentrations were found at Lake Ekoln near Uppsala (15 ng L − 1 ), which will eventually be transported to Stockholm's drinking raw water area (Tröger et al, 2018).…”

Fly Ash-Based Waste for Ex-Situ Landfill Stabilization of Per- and Polyfluoroalkyl Substance (Pfas)-Contaminated Soil

“…For AC, this is attributable to its large surface area [36], with e.g., Calgon carbon Filtrasorb 400 having surface area of around 1050 m 2 g − 1 [37]. For Enk FA-APC, although the sample size was small (n = 7), sorption of PFOS (4.2 m 2 g − 1 ) did not differ from that of other bottom or FA-APC types (range 2.7-45 m 2 g − 1 ) (Fig.…”
