  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 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.
  • Does polyacrylamide structure affect flocculation of bentonite clay?
  • Shaikh and coworkers studied the effect of polyacrylamide structure on the flocculation of bentonite clay. 208 Using turbidity as a powerful measure, they compared flocculations using cationic, anionic, and amphoteric polyacrylamides of varying molecular weights.
  • What is the molecular weight of paetac flocculant?
  • The synthesized flocculants are cationic and highly charged with a viscosity average molecular weight of 340 – 560 KDa and 180 – 190 KDa. The high molecular weight of PAETAC provided better flocculation efficiency for both microalgal species.
