Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation鈥恑nduced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms in runoff.

Review of ASP EOR (alkaline surfactant polymer enhanced oil

PAM (Polyacrylamide) Polyacrylamide ( Fig. 6 a) was the first polymer used as a thickening agent for aqueous solutions. The thickening capability (increase of the corresponding solution viscosity) of PAM resides mainly in its high molecular weight, which reaches relatively high values (>1 脳 10 6 g/mol).

Despite dramatic improvements in water quality, polyacrylamide, also called PAM, has been slow to be adopted as a management practice on the central coast and in much of California. One reason may be because of misunderstandings about how to most effectively use PAM for treating runoff, especially for sprinkler irrigation.
