Model 1: Non-ionic
Nonionic polyacrylamide exists in water in a nonionic form and has no charge. This type of PAM is mainly used for soil improvement and water and fertilizer conservation in farmland. Nonionic PAM can also be used for water treatment in oil fields, mines and coal mines, with excellent sedimentation and filtration effects.
Model 2: Anionic
Anionic polyacrylamide carries a negative charge. This type of PAM is widely used in the field of water treatment to treat various wastewaters and sewage, including industrial wastewater, agricultural wastewater, and urban sewage. Anionic PAM can effectively precipitate suspended matter, remove particulate matter, sediment, and organic matter, and improve water quality.
Model 3: Cationic
Cationic polyacrylamide carries a positive charge. This type of PAM is suitable for the treatment of various water containing anionic substances, such as wastewater containing grease, dyes, proteins, etc. Cationic PAM can adsorb organic matter and anionic particles, aggregate into large particles and then precipitate, which is easy to separate and treat.
