Anionic polyacrylamide (APAM) is a white powder-grained polymer with superior water solubility and exhibits high polymer electrolyte properties in neutral to alkaline media.
The application of APAM is mainly focused on the field of water treatment. When used, APAM can be dissolved to 01%-0.5% aqueous solution, preferably neutral and free of salt impurities. The temperature during the dissolution process is suitable between 50-60 °C, and the low-speed paddle is used for stirring. When adjusting the pH value of the treated liquid, it can give full play to the role of APAM, form flocs by adsorbing suspended solid particles in water, accelerate the sedimentation of particles in suspension, and improve clarity and filtration effect.
In addition, when adding APAM product solutions, care needs to be taken to evenly disperse and avoid the formation of clumps. For the specific amount to be put into the water treatment system, the optimal pH value and the appropriate amount of APAM can be selected through experimentation. In specific applications, APAM is widely used in industrial wastewater treatment, such as steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, etc., and is also suitable for municipal sewage treatment, tap water industry, coal washing, mineral processing, metallurgy, steel industry and other fields. Its mechanism of action is mainly through flocculation and sedimentation, which effectively improves water quality and water treatment efficiency, and provides reliable additives for various water treatment processes.
