polyacrylamide pam flocculants water treatment industrial use
polyacrylamide is widely used in various fields. cationic polyacrylamide is a linear polymer compound; it has many active genes, can be affinity with many substances, and form hydrogen bonds through adsorption. it is suitable for domestic sewage and organic wastewater treatment, such as various feed factories, etc.
recent achievements in polymer bio-based flocculants for low cost,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 polymers or inorganic agents.
transfer and degradation of polyacrylamide-based flocculants
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.
polymer based flocculants review of water purification,alpam, fepam, and hydrolysed pam (hpam) were shown to have good flocculating qualities, with hpam being the least effective and more prone to the overdose of the flocculants studied. proper mixing had a significant impact on flocculation performance.

recent achievements in polymer bio-based flocculants for low cost
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.

application of flocculants in wastewater treatment
to do so, anionic/non-ionic polymeric flocculants are widely used to bring together and agglomerate the slow-settling micro-flocs formed by the coagulant to form larger and denser flocs, thereby facilitating their removal in subsequent sedimentation, flotation and filtration stages (lee et al., 2012).

natural flocculants for the treatment of wastewaters
they have concluded that a modified polysaccharide (positively charged starch) is almost as well or superior efficacy than commercial flocculants to treat suspensions containing negatively charged colloids. in addition, cationic polyacrylamidees are most efficacious when the colloids are strongly negatively charged.

- 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.
- Which polyacrylamide is best for flocculation?
- Cationic polyacrylamides performed the best in terms of high flocculation efficiencies and low optimum flocculant doses.
- How much polyacrylamide flocculant do you need?
- In general, polyacrylamide flocculants with very low charge densities below 10 mol% required very high flocculant doses above 45 mg/L to effectively flocculate the marine algae cells.
- What is the maximum flocculation efficiencies of polyacrylamide?
- In general, the maximum flocculation efficiencies recorded for all polyacrylamide variants ranged from 94 to 100% for flocculant doses varying from 45 mg/L to 1.66 mg/L, respectively, for freshwater Chlorella vulgaris suspensions.
