  • Does polyacrylamide reduce turbidity?
  • Increasing regulations on construction site runoff requires improved sediment and erosion control practices, including the application of polyacrylamide (PAM) to enhance turbidity reduction.
  • Can polyacrylamide be used for erosion control?
  • The chemical polyacrylamide (PAM) is well suited for erosion control enhancement, and its use is described below. PAM is a term describing a wide variety of chemicals based on the acrylamide and acrylate units. When linked in long chains, these units can be modified to result in a net positive, neutral, or negative charge on the PAM molecule.
  • Which treatment chemicals reduce stormwater-based sediment export from construction sites?
  • number of treatment chemicals are available for reducing stormwater-based sediment export from construction sites, including polyacrylamide (PAM—a generic term for a broad class of compounds), chitosan, gypsum, alum (aluminum sulfate), and DADMAC (diallyldimethylammonium chloride).
  • How can treatment chemicals improve sediment removal in stormwater treatment ditches?
  • Treatment chemicals can enhance sediment removal in stormwater treatment ditches. For example, tethering soluble polymer along the upstream portion of a ditch that receives sediment-laden stormwater enables settleable floc formation.
