coagulants and flocculants in polymer water treatment

the next chemical reaction is called flocculation, which helps create even larger flocs or macro-flocs. in this step, a water-soluble polymer, or flocculant, helps bring together the coagulated particles to form longer and larger particle chains. as the flocculant chains become larger, they become heavier and even visible to the naked eye.

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.
What are polyacrylamide based flocculants?
Polyacrylamide-based flocculants constitute the most important group of water-soluble polymers commercially applied in harvesting freshwater and marine microalgae from their suspensions. This is primarily due to the high reactivity, hydrophilic nature and relatively low costs associated with their monomer acrylamide .
Are cationic polyacrylamides effective at a fixed flocculant dose?
The efficiency of four high molecular weight cationic polyacrylamides FO 4450, FO 4650, FO 4800 and FO 4990 at a fixed flocculant dose was analyzed by Garzon-Sanabria et al. on marine microalgae Nannochloropsis salina cultures in the presence and absence of algogenic organic matter.
Are nanocomposite flocculants based on synthetic polymers?
Most of the literature presents, however, nanocomposite flocculants based on synthetic polymers. An example of nanocomposite with using both synthetic and natural polymer is mentioned earlier graft copolymer of polyacrylamide/xanthan gum with silica nanoparticles
