What are polyacrylamides (Pam)?

Polyacrylamides (PAM) are synthetic polymers available in both powder and liquid (emulsion) form (Needham & Doe, 1987; Chang, 1978; Donaldson et al., 1989). These polymers are manufactured in a variety of ways to yield a wide range of physical and chemical properties that make them candidates for many different oilfield applications.

What is polyacrylamide used for?

Polyacrylamide (PAM) has been sold in the United States since 1995 for reducing irrigation-induced erosion and enhancing infiltration. PAM's soil stabilizing and flocculating properties have also… Influence of polyacrylamide application to soil on movement of microorganisms in runoff water.

Does granular polyacrylamide reduce soil loss by water?

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… Water loss through surface runoff is a significant constraint for rainfed agricultural lands across the Mediterranean region.

Can Pam polymer reduce soil cracks and increase soil strength?

Several experiments have been conducted to investigate PAM polymer in high plasticity silt soils to reduce soil cracks and increase soil strength properties. In this study, Polymer was mixed in soil with different PAM variations (0.2%; 0.4%; 0.6%, 0,8% and 1% by weight).

Can polyacrylamide polymer reduce cracking during wetting-drying cycles?

This paper presents the potential of polyacrylamide (PAM) polymer to reduce cracking during wetting-drying cycles. Several experiments have been conducted to investigate PAM polymer in high plasticity silt soils to reduce soil cracks and increase soil strength properties.

Can polymeric polyacrylamide reduce soil eutrophication?

Both PAM and BP applications may not induce eutrophication with stable levels of total contents of N and P and the use of polymeric soil amendments is an environmentally friendly way to mitigate soil erosion and nonpoint source pollution. Expand The use of anionic polyacrylamide (PAM) as a soil conditioner could help prevent soil loss by water.
