| Abstract | The influences of biological and chemical extractions of heavy metals on the physical and chemical properties of sludge biocolloids and the stability of a concentrated sludge suspension formed on the municipal wastewater biological treatment plant are compared. The most significant changes occur at the biological heterotrophic process, namely: increase of the organic component by ∼10%, hydrophobization of biocolloids surface, decrease of their negative charge, and increase of the sedimentation rate by 10–20 times as compared with chemical processes. |
