  • What is the flocculation ability of Pam-hade compared with poly acrylamide-N-acryloyl-?
  • The flocculation ability of the novel PAM-HADE was compared with that of poly (acrylamide- N -acryloyl-1,2-diaminoethane hydrochloride) (PAM-LADE) as its linear alternative in 1 wt% kaolinite suspension.
  • How do high molecular weight PAMS work as flocculants?
  • High molecular weight PAMs (10 6 to 10 7 g mol −1) work as flocculants by causing suspended particles to bind together to form larger aggregates, which can settle out quickly from solution leaving a clear supernatant (Heath et al. 2006).
  • Can cationic polyacrylamide flocculants be used in river water?
  • The amount of flocculant added is 1/50 of that of inorganic flocculants, but the effect is several times higher than that of inorganic flocculants. For river water with severe organic pollution, it is better to use inorganic flocculants in conjunction with cationic polyacrylamide flocculants.
  • 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.
