Cationic polyacrylamide copolymers (PAMs): environmental half life determination in sludge-treated soil | Environmental Sciences Europe

Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).

Polyacrylamide in Agriculture and Environmental Land Management

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

Polyelectrolyte polymers¡ªTypes, forms, and function

The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers [80] .

Role of Polyelectrolytes in the Treatment of Water and Wastewater

10.3.2.3.1 Anionic Polyacrylamide (PAM) High molecular weight carboxylic acid polymers derived from polyacrylamide are used as flocculant in water industries. Copolymers with anionic structure are prepared by copolymerization of acrylic acid and acrylamide or its salts, or by polymerization of acryl amide followed by partial hydrolysis as shown in Fig. 10.8 (Haydar and Aziz 2009 ).
