What is polyacrylamide used for?

Polyacrylamide (PAM) Polyacrylamides (PAMs), are polymer-based materials used to facilitate erosion control and decrease soil sealing by binding soil particles, especially clays, to hold them on site. In addition, these types of materials may also be used as a water treatment additive to remove suspended particles from runoff.

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.

Does polyacrylamide reduce soil erosion in furrow irrigation?

Research results indicated that PAM application decreased soil erosion in furrow irrigation significantly (Trout et al., 1995). Polyacrylamide treatments showed the greatest infiltration improvement and erosion reduction compared with the controls.

Can polyacrylamide be used in steep rocky slope stabilization projects?

Overall, the results of this study could promote polyacrylamide application in the steep rocky slope stabilization projects to reduce nutrient losses and soil erosion of substrate material. This research was funded by the National Natural Science Foundation of China (Project Nos. 41501563, 41401618 and 21507077).

Which Pam treatments reduce soil erosion?

All PAM treatments reduced soil erosion by 18.9 to 39.8% compared with the control group (Fig. 4). The PAM types that performed best in erosion reduction for the substrate material was the M18-C30 treatments.

Does polyacrylamide reduce phosphorus and nitrogen losses?

The results showed that: (1) Polyacrylamide application reduced total nitrogen losses by 35.3% to 50.0% and total phosphorus losses by 34.9% to 48.0% relative to the control group. (2) The losses of total nitrogen and total phosphorus had significant correlation with the molecular weight.
