transfer and degradation of polyacrylamide-based flocculants,this review summarizes the literature which gives information and scientific data on the fate of pam-based flocculants in hydrosystems. pam and associated amd have been considered, and three main families of phenomenon have been investigated: transport, adsorption, and degradation.
polymer based flocculants review of water purification
anionic pam; the most important category of pam, can be made by copolymerizing acrylamide with acrylic aid or partially hydrolysing polyacrylamide. the mw of pam may also be easily adjusted throughout the manufacturing process; intentional degradation can also tune in the mw of pam.

the depressing effect of an anionic polyacrylamide on
high molecular weight polymers based on polyacrylamide (pam) are used successfully as flocculants [5].pam are non-ionic polymers with amide being the primary functional group (fig. 1 a) which forms the molecules through a polyaddition processes [6].
- Can natural polymer flocculant be used as a terpolymer in water treatment?
- Natural polymer flocculant possesses an exciting prospect in water treatment due to its non-toxicity, wide source, low cost and biodegradability. In this work, we have successfully synthesized the anionic terpolymer of carboxymethyl cellulose-itaconic acid‑sodium alginate (CIS) by microwave-assisted copolymerization.
- What is a flocculant used for?
- Previously, mainly inorganic compounds (such as aluminum sulfate and iron chloride) were used for water and wastewater treatment, owing to their high availability and low price, but currently polymers (both synthetic and natural) are increasingly popular flocculants.
- Which flocculants are used in wastewater treatment?
- Summary of chitosan, cellulose, and alginate-based flocculants used in the treatment of wastewater TOC, total organic carbon; CNC, cellulose nanocrystal. Stimuli-responsive polymers are a class of macromolecules that undergo conformational changes and switch their solubility when the right stimulus is applied.
- Are polymer-based flocculants effective in treating wastewater from mining industries?
- However, Sarkar et al., demonstrated the efficacy of naturally abundant polymer-based flocculants/adsorbents for treating wastewater from mining industries [ 102 ].
