What are non ionic organic polymer flocculants?

Non-ionic organic polymer flocculants are mainly polyacrylamide. It is obtained by polymerization of acrylamide. Polymers such as polyacrylic acid, sodium polyacrylate, calcium polyacrylate, and alkali hydrolyzate of polyacrylamide. Copolymers of styrene sulfonate, lignosulfonate, acrylic acid and methacrylic acid.

Is polyacrylamide a comonomer?

Polyacrylamide (PAM) is the basis for most commercial polymeric flocculants mentioned in the literature (anionic, cationic, or non-ionic); this polymer is also modifiable with combinations of comonomers.

What is a polymer flocculant?

Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [8, 9, 10]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.

Can polycarbonate & polyacrylic acid be used for flocculation?

When employing each polymer specifically, Al Dawery demonstrated that combining a blend of polycarbonate and polyacrylic acid for flocculation results in improved liquid clarity. The combination of flocculants could raise the sludge volume index by 70%, compared to 40% in the case of polycarbonate alone.

Are polymer flocculants a new approach to obtaining flocculants?

A New Approach in Obtaining Flocculants 7. Conclusions Polymer flocculants are used to promote solid–liquid separation processes in potable water and wastewater treatment. Recently, bio-based flocculants have received a lot of attention due to their superior advantages over conventional synthetic …
