Investigating the coagulating capacity of advanced aluminium-containing coagulants in natural water treatment

Summary

The results of testing three new coagulants developed at the A. A. Baikov Institute of Metallurgy and Material Sciences of the Russian Academy of Sciences: two North-Onega bauxite-based coagulants and one red-mud-based coagulant are presented. The test results showed that the overall performance of water treatment with optimal dosages of the new coagulants was practically similar to the treatment with traditional aluminium sulfate, except for the red-mud-based coagulant that increased the concentration of iron ions in water after treatment.

Key words

iron , coagulant , turbidity , natural water treatment , chromaticity , efficiency of treatment
