Organic flocculants come in three forms: solid; emulsion (polymer in an organic solvent emulsion); solution (approximately 20 g · L –1 in a water-based medium). The use of solid or emulsion flocculants always requires a specially prepared solution. These products always require secondary dilution (see section using “polyelectrolyte” polymers).
