degradation of polyacrylamide and its significance in nature
high quality flocculant polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction enhancer.
polymer based flocculants review of water purification,when employing each polymer specifically, al dawery [110] demonstrated that combining a blend of polycarbonate and polyacrylic acid for flocculation results in improved liquid clarity. the combination of flocculants could raise the sludge volume index by 70%, compared to 40% in the case of polycarbonate alone.
application of flocculants in wastewater treatment
abstract. flocculation is an essential phenomenon in industrial wastewater treatment. inorganic coagulants (salts of multivalent metals) are being commonly used due to its low cost and ease of use. however, their application is constrained with low flocculating efficiency and the presence of residue metal concentration in the treated water.
high performance, cost-effective and ecofriendly flocculant,in general, the anionic cis flocculant shows excellent cost effectiveness, where the predicted operation cost of as-prepared cis is about 60 % of conventional polyacrylamide flocculant. it also has the advantages of excellent ecofriendliness and rich raw material source, indicative its potential applications of wastewater treatment.
optimizing the flocculation effect of cationic polyacrylamide
cationic polyacrylamide (cpam) is a commonly used flocculant for water treatment. factors that affect the flocculation effect and can be controlled manually include the type and dosage of cpam, wastewater ph, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of cpam. in this paper, the optimal flocculation conditions of a novel cpam were
water treatment flocculant polymer highchem trading,anionic polymer and cationic polymer are flocculants / flocculation chemicals used in waste water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering. these are normally used in conjunction with a coagulant chemical, poly aluminum chloride.
water soluble polymer flocculants synthesis
flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. 35 polyacrylamide is the most important water soluble nonionic flocculant because its monomer, acrylamide

water soluble polymer flocculants synthesis,in addition to the rate of polymer adsorption and particle collisions, the rate at which the adsorbed polymer chains relax on the particle surface (eventually forming a flattened conformation) is crucial in determining the extent of flocculation, defined by gregory as equilibrium and nonequilibrium flocculation. 9 in the latter, the adsorbed polymer is still extended when particles collide
