What are water soluble polymer flocculants?

Abstract Water soluble polymer flocculants are important constituents of solid–liquid separation units for the treatment of a variety of process-affected effluents. The systematic development of a …

Is hydroxypropyl methyl cellulose grafted with polyacrylamide a biodegradable flocculant?

HPMC-g-PAM was found to be an efficient flocculant. The nature of the developed flocculant is biodegradable. Polymer bridging is the dominating mechanism for this system. Herein, the development and application of a high performance polymeric flocculant based on hydroxypropyl methyl cellulose grafted with polyacrylamide (HPMC-g-PAM) is reported.

Which cationic polyacrylamide is synthesized through UV initiation?

Recently, Ma et al. used acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride (DMC) to synthesize a novel cationic polyacrylamide (CPAM) through low-pressure ultraviolet (UV) initiation.

How do short chain polyelectrolytes cause flocculation?

On the other hand, short chain polyelectrolytes (charged polymers) often induce flocculation by compression of the double layer thickness, allowing the particles to aggregate due to van der Waals attraction forces.

Are systematic advances in polymer flocculants possible?

The authors believe that systematic advances in this area can only be achieved when these two aspects are brought together during the design and optimization of polymer flocculants. The authors declare no conflict of interest. Vahid Vajihinejad is a Ph.D. candidate at the University of Alberta under the supervision of Professor João Soares.

Does hydrolyzed polyacrylamide have a better settling rate than bitumen?

Using QCM-D, Klein et al. showed that hydrolyzed polyacrylamide had a greater affinity for “clean” surfaces (Al 2 O 3) than for bitumen-contaminated surfaces. 183 They also measured the initial settling rate of tailings as a function of their bitumen content.
