TL;DR: The homogeneous surface diffusion model (HSDM) was used to predict PAC doses required to reduce MIB and geosmin concentrations to below 10 ng L-1 at four water treatment plants in Adelaide, South Australia and it was found that higher doses of PAC were required for both compounds to produce acceptable quality water when turbidities rose above 26 NTU.

TL;DR: The NOM in a natural water sample displayed the greatest competition with MIB, due to the presence of small compounds that were lost during the concentration and desalting procedures used to obtain the NOM fractions.

TL;DR: The presence of dissolved organic matter (humic material in particular) in source water decreases the effectiveness of granular activated carbon filters in the treatment of drinking water as discussed by the authors, which may be due to an increase in the negative charge on the carbon surface and a decrease in available surface area after adsorption.

TL;DR: In this article, the adsorption of microcystin-LR by eight different powdered activated carbons (PACs) was investigated and found to vary markedly between carbons.

TL;DR: The results confirmed that both cyanotoxins microcystin LR and LA and anatoxin-a were ozonated at a range of ozone doses in four treated waters with very different water quality and indicated that a direct reaction with molecular ozone could be responsible for the destruction.
