Proxies to monitor the inactivation of viruses by ozone in surface water and wastewater effluent

Urs von Gunten, Tamar Kohn, Camille Wolf, Annalisa Pavese

Ozone treatment is an effective barrier against viral pathogens, therefore it is an integral part of many water and wastewater treatment trains. However, the efficacy of ozone treatment remains difficult to monitor, due to the lack of methods to track viru ...

Organic substrate diffusibility governs microbial community composition, nutrient removal performance and kinetics of granulation of aerobic granular sludge

Christof Holliger, Eva Reynaert

Basic understanding of formation of aerobic granular sludge (AGS) has mainly been derived from labscale systems with simple influents containing only highly diffusible volatile fatty acids (VFA) as organic substrate. This study compares start-up of AGS sys ...

Fate of Cr(III) during ozonation of secondary municipal wastewater effluent

Urs von Gunten, Caroline Gachet Aquillon

In the present study, the fate of trivalent chromium (Cr(III)) during ozonation of ultrapurified water and wastewater effluent was investigated. In experiments conducted in phosphate buffered ultrapurified water, O3 alone in excess was inefficient to oxidi ...
