The efficient removal of AOM (Algal Organic Matter) by coagulation requires sufficient particle destabilization at a pH value at which coagulants (AlFe hydrolysing salts) bear the highest charge and the organic macromolecules provide the most active centres. It was ascertained that due to their high affinity with metal ions, several AOM peptides/proteins inhibit coagulation by the formation of highly soluble metal-peptide/protein complexes. This leads to an increase in dissolved/colloidal Al or Fe that cannot be effective in the coagulation process. This study is aimed at the description of inhibition effect of peptides/proteins isolated from cyanobacterium Microcystis aeruginosa on coagulation by formation of complexes with Fe.
