Combined coagulation – ultrafiltration technology of Dniper river water treatment was investigated in this study. High humic compounds content, that typical for Dniper river water, can essentially decrease efficiency of water pretreatment as by traditional technologies so by an ultrafiltration. Performed investigations showed that in-line dosing of coagulant before ultrafiltration stage can increase efficiency of color and permanganate oxidation removal.

Key words: coagulation, ultrafiltration, humic compounds, aluminium oxychloride.
