  • 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 polyacrylamide injection reduce effluent turbidity?
  • Many construction projects need to pump turbid water from borrow pits or other excavations into stilling basins or sediment filter bags prior to discharge. This study evaluated the effectiveness of these devices with polyacrylamide (PAM) injection to reduce effluent turbidity.
  • Are polyacrylamides for stormwater clarification soil specific?
  • 894 - 1 Polyacrylamides for stormwater clarification are soil specific. PAM shall be tested with on-site soil and water samples to determine which formulation performs most effectively. Polyacrylamide must mix completely within the water column for sufficient flocculation of sediment to occur.
  • What is the optimal Pam concentration for turbidity reduction?
  • The PAM solution was injected to achieve a concentration of 5 mg L − 1 in the pumped water, which was the optimal PAM concentration for turbidity reduction in the laboratory tests.
