What is water soluble anionic polyacrylamide (PAM)?

Water soluble anionic polyacrylamide (PAM) was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1–10 g m −3 in furrow irrigation water. Water flowing from PAM treated irrigation furrows show large reductions in sediment, nutrients and pesticides.

Is polyacrylamide effective for erosion control and water quality protection?

Since the early 1990s use of polyacrylamide (PAM) has been shown to be an effective strategy for erosion control and water quality protection ( Lentz and Sojka, 1994 ).

What is polyacrylamide (PAM)?

Polyacrylamide (PAM) is a generic chemistry term, referring to a broad class of compounds. There are hundreds of specific PAM formulations that vary in polymer chain length and number and kinds of functional group substitutions. In some chain segments PAM amide functional groups are substituted with groups containing sodium ions or protons.

Can Pam be used as a water quality protection measure?

PAM treatment also filtered significant amounts of NH 4, PO 4 and total P in cattle and swine wastewater. This points to the potential of developing PAM as a water quality protection measure in combination with large-scale animal feeding operations.

Can anionic polyacrylamide (PAM) be used to treat animal waste?

The application of anionic polyacrylamide (PAM) to soils and/or vegetative treatments may also provide a cost-effective way to dramatically reduce bacteria and nutrient loads in animal waste effluent and thereby reduce pollution in surface and ground waters receiving these effluents.

Is Pam a water soluble polymer?

In the 1990s, water soluble anionic PAM was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1–10 g m −3) in furrow irrigation water ( Lentz et al., 1992, Lentz and Sojka, 1994, McCuthan et al., 1994, Trout et al., 1995, Sojka and Lentz, 1997, Sojka et al., 1998a, Sojka et al., 1998c ).
