Product Usage

AnionicCationic Polyacrylamide is available in anionic, cationic, and non-ionic types, and is a highly effective water-soluble polymer flocculant. In water treatment, anionic PAM is suitable for treating wastewater containing positively charged suspended particles, such as steel processing and stone cutting wastewater, promoting rapid sedimentation through charge neutralization and adsorption bridging. Cationic PAM is suitable for negatively charged organic colloidal wastewater, such as municipal sewage, printing and dyeing wastewater, and paper mill effluent, effectively dewatering, removing turbidity, and improving sludge dewatering efficiency. Additionally, it is used as an oil displacement agent in petroleum extraction, as well as in textile sizing and soil conditioning. Its advantages include low dosage requirements and fast flocculation rates.
