Evaluation of Turbidity Reduction Using Polyacrylamide with ...

To reduce turbidity and keep eroded sediment on site, this research was conducted to evaluate the potential for turbidity reduction using polyacrylamide (PAM) flocculants with sediment control best management practices (BMPs). Previous research has shown significant turbidity reduction when applying granular PAM to linear sediment control BMPs.

Streams and lakes adjacent to construction sites are often heavily impaired by sediment and turbidity coming from areas of exposed soil. A study was conducted to determine if the application of polyacrylamide (PAM) can reduce erosion and runoff turbidity on moderate to steep slopes at construction sites.

Which polyacrylamide is used for sediment control and turbidity reduction?

Can polyacrylamide remove sediment from stormwater discharge?

This may include the combined usage of other sediment control best management practices in order to effectively remove sediment from stormwater discharge. 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.

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.

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 turbidity reduction & sediment control?

Any PAM treatment system for turbidity reduction and sediment control shall be designed and installed to achieve significant reductions in turbidity levels in stormwater discharged through the system. OPTIONAL BAFFLE PIT may be used on the plan sheet(s).

Can polyacrylamide be used to flocculate sand?

Polyacrylamide shall not be used in an effort to flocculate large sediment particulates such as sands and any PAM treatment system used shall be designed to protect the PAM from heavy sediment loads and larger sized sediment particulates. When handling and mixing PAM Manufacturers’ recommendations and criteria shall be followed.
