  • Which polyacrylamide is used for sediment control and turbidity reduction?
  • Polyacrylamides used for sediment control and turbidity reduction shall have a charge density of 8-35% by weight and have a molecular weight of 6 to 24 mg/mole. The acrylamide used in the PAM shall have active monomer limits of ≤0.05% by weight.
  • Can Pam be used for turbidity control?
  • Previous studies tested PAM applications for turbidity control in various construction site settings such as check dams [ 2, 10, 11 ], settling basins [ 12, 13, 14 ], erosion control blankets as ditch liners [ 9, 11 ], and dewatering operations [ 5, 15 ].
  • What is a polyacrylamide & oligomer?
  • Polyacrylamide (PAM) & oligomers PAM is a water-soluble, odorless, white synthetic linear polymer with the repeating formula (-CH 2 CHCONH 2 -), and its monomer used is AM. Its molecular weight (MW) of PAM ranges from 10 5 to >10 7 Da, with a length of up to six million monomer units.
  • 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.
