Abstract
A method for cyanobacteria removal in an aqueous solution, includes a first main step of determining a percentage of coagulable dissolved aromatic organic matter to remove corresponding to a cyanobacteria percentage concentration to remove, a second main step of determining an optimal coagulant dose corresponding to the determined percentage of coagulable dissolved aromatic organic matter to remove and a third main step of applying the optimal coagulant dose as the adjusted coagulant dose for cyanobacteria removal. The invention may comprise an evaluation of cyanobacteria concentration in the aqueous solution. The invention may comprise a metabolite removal step adapted for removing dissolved cyanobacteria metabolites, comprising applying a powdered activated carbon dose/contact time couple as by determining at least one Freundlich coefficient for each metabolite type in the aqueous solution.
