high molecular weight partially hydrolyzed polyacrylamide (pam) can be bio-hydrolyzed on the amide side group, however, solid evidence regarding the biological cleavage of its main carbon chain backbone is limited. in this study, viscometry, flow field-flow fractionation multi-angle light scattering (fff-mals), and attenuated total reflectance
polyacrylamide polymer bio-based flocculants for water treatment.the flocculants, designed for coal slime water treatment, were characterized using the ftir, xrd and sem methods. it has been shown that water turbidity was reduced by ~97% and ~94%, while cod removal was ~78 and ~74% in the presence of fe 3 o 4 -chitosan-cellulose and fe 3 o 4 -chitosan-biochar, respectively.

what is anionic polyacrylamide? anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. no studies on the environmental fate of polyacrylamide are available. as a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. anionic polyacrylamide has a low acute toxicity concern to aquatic
high quality price flocculant pam powder polyacrylamide,poly(acrylamide), granular (non-ionic), in the paper industry, pam is used as a retention and drainage aid, enhancing the efficiency of papermaking by improving the retention of fillers, fibers, and other materials used in the paper matrix.

ultrasound-initiated synthesis of cationic polyacrylamide for oily wastewater treatment: enhanced interaction between the flocculant and,2.7.3. characterization of morphological properties of flocs floc size was measured by a laser diffraction polyacrylamide (mastersizer2000, malvern, uk). dynamic sludge flocs size was monitored during the whole formation, breakage and re-flocculation process. d 50 (50% of the flocs were of the sizes in the range 0–d 50) was adopted to represent the average floc size.
recent achievements in polymer bio-based flocculants for sale
there are numerous studies on cellulose derivatives of anionic polyacrylamide, cationic polyacrylamide and amphoteric nature, as high-performance polymer flocculants. the flocculation efficiency of anionic cellulose (dicarboxylic acid cellulose, dcc) was examined in the coagulation–flocculation treatment of municipal wastewater.
