Polyacrylamide in Agriculture and Environmental Land
Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced 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 × 10 6 g/mol).

hey guys, how are you all doing? I’m so sorry for the lack of posting recently, I’ve been so busy and I just haven’t been able to find the time to take photos ? also I’ve finished my second day of gastrointestinal surgery and so far I’m not really enjoying it that much lol, some of the doctors we’re with aren’t the nicest...
