Vf. Kurenkov et al., Comparison of the efficiencies of aluminum hydroxochloride and sulfate in water treatment with and without polyacrylamide, RUS J AP CH, 73(8), 2000, pp. 1420-1423
The efficiencies of coagulants (aluminum hydroxochloride and sulfate) in wa
ter treatment with and without a flocculant (polyacrylamide) were compared,
depending on the concentrations of the coagulants and flocculant and on th
e method and time of their addition to water.
