  • 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 is Pam used for in water treatment?
  • PAM is also widely used as a flocculant in drinking water treatment (at concentrations <1 mg/L). 37 PAM can create bridges between destabilized particles, forming micron-size aggregates with good settling properties. 38 Cationic, nonionic, and anionic PAM have all been studied for flocculation.
  • What is polyacrylamide (PAM) used for?
  • npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • Why are polymer flocculants used in water purification?
  • Therefore, in modern water purification technologies, polymer flocculants are increasingly used. Polymer flocculants cause the formation of large, coherent aggregates (so-called flocs) that settle in the solution. Synthetic polymers are highly effective flocculants at low dosages but have poor shear stability.
