Flocculants are reagents used in wastewater treatment, water treatment to potable levels. On the chemical level these are macromolecular particles capable of adsorbing molecules of the flocculant with particle molecules in the fluid, which form flakes while settling at the bottom. They are divided into organic and inorganic. Inorganic flocculants (silicic acid) are used in industry. Organic flocculants are subdivided into natural and synthetic. The first group includes acrylamide polymers and copolymers. The most common, PAA or polyacrylamide, is used for high-quality treatment of industrial and natural drains. The chemical composition of treated liquids may vary, so it is important to determine the functionality level of the reagent having different molecular weight and charge. Flocculants have cationic, anionic and neutral structure and are suitable for many types of waste. They are marketed in the form of granules, powder or emulsion.
