transfer and degradation of polyacrylamide-based flocculants in hydrosystems: a review environmental science and pollution research manufacturer,the aim of this review was to summarize information and scientific data from the literature dedicated to the fate of polyacrylamide (pam)-based flocculants in hydrosystems. flocculants, usually composed of pams, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. these polymers can contain
effects of different electron acceptors on the methanogenesis
it can be concluded that the biodegradation efficiencies of hpam-containing wastewater with fe 3+ as electron acceptor are greater than that with so 4 2− as electron acceptor. moreover, the biodegradation efficiencies with fe 3+ and so 4 2− as the mixed electron acceptors are higher than that with the sole electron acceptor.
polyacrylamide in water treatment: enhancing efficiency and quality,advantages of pam in industrial water treatment: in industrial water treatment, pam can be used for scale inhibition and corrosion inhibition, helping to maintain the proper functioning of equipment. it can also be employed in the maintenance of cooling water systems, reducing corrosion and microbial growth while enhancing system efficiency.
