Best Practices Guidance for the Use of Anionic Polyacrylamide

PAM aids solid-liquid separation by causing suspended particles to bind and form larger aggregates. The process is known as polymer bridging. One of the most common polymer flocculants on the market. Common uses of PAM as a flocculant: reduction of sediment and nutrient loads to natural lakes and ponds.

The reduction in the negative zeta potential was found to be considerably greater in the presence of cationic polyacrylamide than anionic and amphoteric polyacrylamide, due to an increased adsorbed layer thickness of cationic polyacrylamide. 208 Amphoteric polymers exhibit both cationic and anionic behaviors, and their strength and a relative

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.

Comparison of adsorption ability of PAM, APAM and CPAM on

Abstract Swelling of clay minerals caused by the adsorption of water is one of the main problems encountered in oil well drilling industry during the operations of drilling with water-based fluids. Different types of chemicals can be used as inhibitor to solve the hydration of clay minerals in drilling fluids operations.

The cationic monomers on these microblock segments can be polymerized to form a CPAMD with a new cationic microblock structure. In addition, microwave has mechanical effects such as oscillation, emulsification, and diffusion, which can accelerate the heat and mass transfer process of the reaction system, thus accelerating the reaction rate (Wiesbrock et al. 2004; Hoogenboom and Schubert 2007
