Chlorination and ozonation are effective for the destruction of residual dissolved microcystins and cylindrospermopsin. Anatoxin-a can be effectively removed using ozone, although chlorine is relatively ineffective. Oxidation techniques do not appear to be the best method for the treatment of saxitoxins under normal treatment plant operating conditions. Powdered activated carbon can be effective for the removal of all toxins, except, perhaps, microcystin LA, provided the appropriate carbon and the correct dose is applied. Granular activated carbon filters show a limited lifetime for the adsorption of most microcontaminants, including cyanotoxins. The biodegradation of cyanotoxins across GAC filters shows great potential as a treatment process. algal toxins, cyanobacteria, water treatment This content is only available as a PDF. © IWA Publishing 2004 You do not currently have access to this content.
