Effect of water pH on removal of some heavy metal ions by using pre-hydrolyzed coagulants PAX and aluminium sulfate
Four com. Al-2(SO4)(3) and prehydrolyzed AlCl3-based coagulants were used to removal of color, turbidity, org. matter, Pb, Ni and Cd ions from surface water at pH 6-8.7. The efficiency of Ni, Cd and Pb ions removal was 53-65%, 77-88%, and 80-89%, resp. The efficiency of org. matter removal did not exceed 29%.
