1. Introduction. Partially hydrolyzed polyacrylamide (HPAM) is widely used in various fields, such as enhanced oil recovery, water treatment, and agriculture, as a result of its availability in large quantities and low cost [].However, HPAM has poor temperature and salt resistance, meaning that it cannot meet the requirements for reservoir stimulation under high-temperature and high-salt
Influence of polyacrylamide application to soil
sediment transport in the furrows. The effect was not quantified and the specific chemical polymer used was not identified, although its description would suggest some type of polyacrylamide (PAM) formulation. Mitchell (1986) also noted the clarification of runoff streams but did not quantify sediment effects. The effect

- 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.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
- Does cationic polyacrylamide flocculate Phaeodactylum tricornutum?
- However, Nguyen et al., observed high flocculation efficiency of marine microalgae Phaeodactylum tricornutum with a cationic polyacrylamide flocculant (FO3801). The discrepancy in the literature suggested that a future flocculation study using one type of polymer with multiple marine species.
- How cationic polyacrylamide (PAMC) is prepared?
- Flocculation and mechanism was discussed based on zeta potential and pH analysis. A novel cationic polyacrylamide (PAMC) with various cationic monomer contents were prepared by copolymerizing acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride aqueous solution (DMC) through low-pressure ultraviolet (UV) initiation.
