The use of anionic polyacrylamide (PAM) as a soil conditioner could help prevent soil loss by water. In this study, we determined the effective granular PAM rate that best reduces runoff and soil loss from Oxisols. Furthermore, the effectiveness of the selected PAM rate was tested by applying it in a mixture with gypsum (G) or lime (L). The study was conducted in two phases: (i) Dry PAM rates
Effectiveness of Polyacrylamide (PAM) in Improving Runoff
This study was an evaluation of straw, with or without polyacrylamide (PAM), and wood fiber hydromulch, with or without PAM, for reducing erosion and improving runoff water quality.

Effect of Polyacrylamide Application on Runoff, Erosion
Soil erosion affects soil productivity and environmental quality. A laboratory research experiment under simulated heavy rainfall with tap water was conducted to investigate the effects of anionic polyacrylamide (PAM) application rates (0, 0.5, 1.0, and 2.0 g m −2) and molecular weights (12 and 18 Mg mol −1) on runoff, soil erosion, and soil nutrient loss at a slope of 5°.

The efficiency of PAM in improving aggregate and structural stability relative to untreated soils ranged from 1.01 to 3.90 and the relative SR of kaolinitic < illitic < smectitic samples. These results suggest that the less stable the aggregates the greater the effectiveness of PAM in increasing aggregates stability (i.e., smectitic
A comparative investigation of the effectiveness
Erosion from construction sites significantly affects water quality in receiving streams. A rainfall simulator was used to evaluate the effectiveness of different methods for controlling erosion from construction sites. Erosion control methods investigated included dry and liquid applications of polyacrylamide (PAM), hydroseed, and straw mulch.
High molecular weight (106–3 × 107 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
- Can polyacrylamide contribute to residual polymer formation?
- Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.
