Transfer and degradation of polyacrylamide-based flocculants in

Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. These polymers can contain residual monomer of acrylamide (AMD), which is known to be a toxic compound.

Research on a new cationic polyacrylamide (CPAM) with a

Flocculation is a common method to improve filtration efficiency and purify water quality in water supply plants where the commonly used flocculant is cationic polyacrylamide (CPAM) (Vandamme et al. 2010; Teh et al. 2016). For sludge dewatering, CPAM shows superior conditioning performance and obtained more and more attention.

Ultraviolet-assisted synthesis of polyacrylamide-grafted chitosan

Flocculation is involved in the physical aggregation process of many finely divided or dispersed particles in wastewater to form lager flocs so they are separated from the wastewater through settling (Chang, Hao, & Duan, 2008; Pal, Ghorai, Dash, Ghosh, & Udayabhanu, 2011).

Partially hydrolyzed polyacrylamide: enhanced oil recovery applications

PAM and HPAM are the most extensively used polymers in enhancing oil recovery due to their customized properties and wide availability. Although the usage of PAM and HPAM as an EOR method resulted in increasing the production of oil considerably to overcome the current energy crisis, it is adverse environmental and health issues suggested searching for other eco-friendly alternative polymers.

Enhancing the flocculation of stable bentonite suspension using hybrid

The addition of NADES as a coagulant aid reversed the flocculation activities of the PAMs due to the presence of positively charged NADES that enhances the adsorption of the anionic polyacrylamide (APAM) over the cationic polyacrylamide (CPAM).
