摘要:
Pilot-scale tests were run with ozonation for reduction of 24 pharmaceuticals at 10 full-scale wastewater treatment plants in southern Sweden. Reduction was evaluated based on doses of 3, 5 and 7 g O3/m3 at all plants. The reduction of pharmaceuticals reached on average 65% at 3 g O3/m3, 78% at 5 g O3/m3 and 88% for 7 g O3/m3 in terms of total concentration of pharmaceuticals. Specific ozone dose (ratio O3: TOC) was found to be highly influential on pharmaceutical removal. At two WWTPs, the pharmaceutical removal was severely reduced. © IWA Publishing 2017.
