Effectiveness of Polyacrylamide in Reducing Runoff
Effectiveness of Polyacrylamide in Reducing Runoff and Soil Loss under Consecutive Rainfall Storms Birhanu Kebede 1,2, *, Atsushi Tsunekawa 3 , Nigussie Haregeweyn 4 , Amrakh.
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
Polyacrylamide efficacy for reducing soil erosion
Polyacrylamide reduced SL for all slopes. A higher rate of PAM (40P) had less SL than a lower rate of PAM (20P) at slopes of 20% and 40%. With 40P, the reduction in SL was 72% greater than 0P at 40% slope. Therefore, slope is a critical factor in determining a PAM rate for reducing soil erosion and should be considered for proper application.

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°.
POLYACRYLAMIDE EFFECT ON SEDIMENT YIELD, RUNOFF,
Polyacrylamide effect on sediment yield, runoff, and seedling emergence on a steep slope K. Chaudhari and D.C. Flanagan Introduction Recent estimates indicate that 600 000 ha of land surface is critically disturbed annually in the United States by construction of new urban areas, roads, and highways (Troeh et al., 1991).

Effects of Polyacrylamide and Gypsum on Soil Erosion
This study evaluates the effectiveness of two popular soil amendments of gypsum and polyacrylamide (PAM) in minimizing soil erosion from one soil and one overburden (spoil) material of a mine rehabilitation site in Central Queensland. The treatments included an untreated soil (control), a gypsum application rate of 10 t/ha,
However, APS 705 alone was more effective at reducing turbidity than other PAMs combined with gypsum. PAM effectively decreased turbidity of most soil suspensions and could be very useful in reducing construction site runoff turbidity to meet water quality standards.
Applicability of PAM(Polyacrylamide) in Soil Erosion
Abstract. Surface runoff and erosion are responsible for extensive losses of top soil and agricultural productivity. In this study, a laboratory experiment was conducted to investigate the effects of different polyacrylamides (PAM) on the protection of soil from erosion and turbidity in loamy sand soil.
soil surface against shear-inducing detachment (Lentz and Sojka, 1994), decreasing soil susceptibility to seal formation (Levy et al., 1992; Shainberg et al., 1990, 1992), runoff generation and soil erosion (Smith et al., 1990; Bjorneberg and Aase, 2000); (iii) increasing the size and thus decreasing settling time of particles suspended in
- Which polymers are used in water and wastewater treatment operations?
- The classification of the synthetic organic polymers used in water and wastewater treatment operations is based on the ionic charge present, e.g. cationic, anionic and non-ionic polyelectrolytes. Cationic polyelectrolytes formed the largest number of polymeric coagulants that have been used in CF operations.
- Which coagulants are used in water and wastewater treatment operations?
- Metal and polymer based materials are the conventional coagulants used in water and wastewater treatment operations.
- Why do we use polymeric coagulants in water treatment?
- Relative to the use of the inorganic coagulants in water treatment, the use of polymeric coagulants significantly reduced the coagulant dose requirements, the sludge volume, the ionic load cum the residual aluminium concentrations in the treated water and the process economy (i.e. cost savings of up to 25–30%) [33, 47].
- Can natural polymer coagulants be used in wastewater treatment?
- Using natural polymer coagulants in treating different wastewaters is currently gaining much attention.
