, and nonionic (NPAM) types. This document focuses on the cationic type while also covering the anionic type.
2.Physical and Chemical
3.Main Functions and Applications (What are its
- CPAM is the first-choice flocculant for sludge dewatering. Through charge neutralization and bridging, it rapidly flocculates and dewaters sludge, and is widely used in municipal sewage plants, papermaking and chemical sludge treatment.
- APAM is used for flocculation and clarification of mineral processing, metallurgical and coal-washing wastewater, accelerating the settling of suspended solids.
- Both cationic and anionic PAM serve as retention and drainage aids, improving the retention of fine fibers and fillers.
- APAM is used as an oil-displacing agent, drilling-fluid viscosifier and fracturing-fluid friction reducer.
- APAM meeting sanitary standards is used for drinking water flocculation.
- The cationic type suits negatively charged sludge and colloids, while the anionic type suits positively charged inorganic particle systems; the choice depends on the charge characteristics of the water.
