Definition and Usage Area of Anionic polyelectrolyte

Anionic polyelectrolyte, In wastewater treatment systems, after the coagulant (coagulation) process, the anionic polyelectrolyte performs the flocculation process.

Depending on the type of waste in chemical wastewater treatment plants, anionic polyelectrolyte is applied by making a solution with water. It is a type of polymer used in the dewatering of sludge originating from biological treatment processes. It is used in drinking water and wastewater treatment, Paper Industry, Petroleum Industry, Mining, Agriculture, Textile, Cosmetics industry.

Anionic Poly Electrolyte is specially designed to improvise filtration and purification processes in sugar processing. This organic-based copolymer coagulant is effective in complex systems that coagulate solids and form flocs immediately. This product is processed more discreetly to make it compatible with any pH range.

Anionic Polyelectrolyte Powder is a medium anionic charged powder polyelectrolyte for use as a solidifier in direct filtration for the precipitation of inorganic suspended solids, wastewater

Polyelectrolytes are polymers with dissociating groups in their repeat units. They can be divided into polycations and polyanions and polysalts. Like ordinary electrolytes (acids, bases and salts), they dissociate in aqueous solutions (water) and bear one or more charges depending on the pH value. Thus, the properties of polyelectrolytes are similar to both electrolytes and polymers. The salts, i.e. the products of a polyacids (polyanions) with a monomeric base and vice versa are called polysalts. Like regular salts, their solutions are electrically conductive and like polymers, their viscosity strongly depends on the molecular weight and polymer concentration.

The three most common anionic groups are carboxylate (–COO^–), phosphonate (–PO₃H^–, –PO₃^2-), and sulfonate (–SO₃^–) and the most common cationic groups are primary, secondary and quaternary ammonium (–NH₃⁺, =NH₂⁺ & ≡N⁺). The type of ionic group, its counter ion and the structure of the repeat unit determine the properties of a polyelectrolyte such as solubility in water and other polar and hydrogen-bonding liquids (alcohols etc.), electrical conductivity, and solution viscosity. Unlike nonionic polymers, these properties strongly depend on the pH and salt content.
