Science of the total environment [online], 659, pages 1403-1414. Available from: https://doi.org/10.1016/j.scitotenv.2018.12.337

Many toxic and/or noxious cyanobacteria appear in nature with a filamentous, stacked cell arrangement called trichomes. Although water treatment can be optimized to keep cyanobacterial cells intact and to avoid the release of toxic and/or noxious com...

A paradigm-shift in water treatment: in-reservoir UV-LED-driven TiO2 photocatalysis for the removal of cyanobacteria: a mesocosm study. Presented at the 12th International conference on toxic cyanobacteria (ICTC 2022), 22-27 May 2022, Toledo, USA.

Potentially harmful cyanobacteria challenge potable water treatment globally, with high biomass events, and dissolved toxic and nuisance metabolites. Retrofitting existing water treatment infrastructure is often impractical (if not impossible) and of...
