Anionic flocculants are co-polymers of acrylamide with increasing proportions of acrylate groups, which give the polymers negative charges, and thus anionic active character, in aqueous solution. Our anionic polyacrylamide is available in solid powder and emulsion forms.
The solutions of anionic polymers must be prepared in suitable plants equipped with dry powder feeding and dispersion units and with continuous and moderate agitation. The dissolution water must have a temperature included between 10°C and 40°C; For a correct use of anionic polyelectrolyte and in order to achieve the best possible results, it is necessary to allow a "maturation" time of 60 minutes. When treating turbid water, the flocculants solution must be added to the water in a point of average turbulence, in order to achieve a thorough and homogeneous mixing without impairing the flock formation. Recommend operating concentration is 3g/l, and the maximum operating concentration is 15g/l.
