- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a water-soluble linear polyelectrolyte with high molecular weight and positive charge density. Because of its low cost, high efficiency, and simple operation, CPAM is widely used as a chemical conditioner for flocculation pretreatment of sludge before mechanical dewatering (Sun et al. 2018; Zhou et al. 2014 ).
- What are cationic polyacrylamide copolymers (PAMS)?
- Keywords: Transformation, Sludge-amended soil, Outdoor lysimeter study Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management.
- Is CPAM a cationic microblock?
- It has been shown that the flocculation performance of CPAM is related to the distribution and sequencing of cationic units in the molecular chain (Feng et al. 2018b). The continuous arrangement of cationic units in CPAM can form cationic microblock structure.
- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
