The commercial polymeric flocculants are usually based on
polyacrylamide (PAA) (Bratby, 2006). Mainly, their applications
include treatment of natural and wastewaters, and ore flotation
tailings. Major consideration for wide use of PAA was high formation
rate of a high molecular mass polymer. Other considerations
to be mentioned are low power consumption with the monomer
separation as a crystal, and that PAA has proved itself as nontoxic
for humans, animals, fish and vegetation (Seybold, 1994).
