polyacrylamide pam flocculants water treatment industrial use

polyacrylamide is widely used in various fields. cationic polyacrylamide is a linear polymer compound; it has many active genes, can be affinity with many substances, and form hydrogen bonds through adsorption. it is suitable for domestic sewage and organic wastewater treatment, such as various feed factories, etc.

transfer and degradation of polyacrylamide-based flocculants

this review summarizes the literature which gives information and scientific data on the fate of pam-based flocculants in hydrosystems. pam and associated amd have been considered, and three main families of phenomenon have been investigated: transport, adsorption, and degradation.

recent achievements in polymer bio-based flocculants for low cost,the water solutions of ph 7 or 9 contained alkali and alkaline–earth metal chlorides in the concentration of 0.5 m. cationic and anionic acrylamide copolymers were used as flocculants (dose range 0–700 g/ton of dry mass of solid).

what is anionic polyacrylamide? one of the most common polymer flocculants on the market common uses of pam as a flocculant: reduction of sediment and nutrient loads to natural lakes and ponds wastewater and drinking water treatment clarification of effluents in industries like pulp amp paper, aquaculture

optimization conditions to obtain cationic polyacrylamide,the 1 h–nmr spectral results agreed well with previous data that indicated that cpam copolymers were successfully synthesized from am and dmc . the chemical shifts of 5.6–6.2 ppm (corresponding to ch 2 =ch– and ch 2 =c–) [ 27 ] did not show any peaks in figure 4 , which means that the monomers reacted completely and the reactions had a

water soluble polymer flocculants synthesis

anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.

mechanical degradation of polyacrylamide at ultra high.the extent of degradation increased with , approximately following an empirical scaling relationship of for the polyacrylamide with an initial mw ≈ 10 7 da. degraded pam with lower mw ( 10 6 da) showed minimal degradation during multiple flow passes even at high deformation rates, suggesting that most mechanical degradation occurs at the

transfer and degradation of polyacrylamide based flocculants

67 high molecular weight pams can be modified to develop non-ionic, anionic, or cationic properties for 68 specific uses (scott et al., 1996). however for environmental applications which are described in this 69 article, anionic pams are preferred because of their extremely low aquatic toxicity compared to

textile industrial wastewater treatment by polyacrylamide,g of polyacrylamide aided magnesium chloride was applied in treating textile industrial wastewater. four independent factors, i.e. ph, dosage, agitat. on speed and time were used to determine their effects on colour removal (%) and cod reduction (%). all. independent factors were proved to have significant effect on the colour removal and cod
