polyacrylamide pam flocculants water treatment industrial use
polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction.dissolved into 0.3% concentration and cross-linking agent added. it can be sprayed on desert to prevent and solidify sand.
journal of the taiwan institute of chemical engineers.polyacrylamide (pam) is extensively utilized in oilfield polymer flooding for enhanced oil recovery, owing to its high molecular weight and the resulting high viscosity in low-concentration aqueous solutions. however, the increased exploitation of oilfields has led to a rise in wastewater volumes containing pam.
recent achievements in polymer bio-based flocculants for low cost
among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (pam)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [8,9,10]. the acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
