What is a high molecular weight polyacrylamide (PAM)?

… High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.

What is anionic polyacrylamide used for?

Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment. Anionic polyacrylamide is suitable for high concentrations of positively charged inorganic suspensions, as well as coarse suspended particles (0.01-1mm), with a Ph value of neutral or alkaline solution.

What is polyacrylamide used for?

Polyacrylamides are water-soluble synthetic linear polymers made of acrylamide or the combination of acrylamide and acrylic acid. Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment.

What is cationic polyacrylamide used for?

Cationic polyacrylamide can also be used as an oil field chemical additive, such as clay anti swelling agent, thickening agent for oil acidification and paper making reinforcing agent. Nonionic polyacrylamide is suitable for separation of suspended solids in organic and inorganic mixtures, and the solution is acidic or neutral.

Who makes acrylamide based flocculants?

SNF is the world’s leading manufacturer of water-soluble polymers and acrylamide monomer, which is the primary ingredient for polyacrylamide-based flocculants.

Can nonionic polyacrylamide be used as a sewage treatment agent?

Nonionic polyacrylamide can be used as a sewage treatment agent for acidic slurry, making the suspended particles flocculate and precipitate. * You have to Login or Register to download this file.
