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
polyacrylamide (pam) is the basis for most commercial polymeric flocculants mentioned in the literature (anionic, cationic, or non-ionic); this polymer is also modifiable with combinations of comonomers. anionic pam; the most important category of pam, can be made by copolymerizing acrylamide with acrylic aid or partially hydrolysing
transfer and degradation of polyacrylamide-based flocculants,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 pam, 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
recent achievements in polymer bio-based flocculants for sale
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. the acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
iop conference series: materials science and engineering,some types of chemical flocculants that are often used in the flocculation process are polynatriumacrylate, polyacrylamide, copolymers of acrylamide and n,n − dimethyl amino propylene acrylate. mainly because of their low prices, where their market prices are much lower compared to chemical flocculants as shown in table 1.

flocculation characteristics of polyacrylamide grafted.this suggests that the flocs formed with high dosage of flocculant were harder than the flocs formed with low dosage of flocculant [47]. with further increase in flocculant dosage over 2.50 ppm, rate of flocculation declines as the kinetics constant k 1 for aggregation of particles reduced and the aggregate breakage constant k 2 increased.
new tech polyacrylamide for wastewater treatment flocculant
the non-ionic polyacrylamide magnafloc 351 produced the lowest removal efficiency of 79.9% with a high optimal flocculant dose of 10 mg/l [39]. in contrast to cationic polyelectrolytes, flocculation by anionic and non-ionic polyelectrolytes occurs fundamentally employing chemical forces instead of electrostatic forces.

- What are polyacrylamide based flocculants?
- Polyacrylamide-based flocculants constitute the most important group of water-soluble polymers commercially applied in harvesting freshwater and marine microalgae from their suspensions. This is primarily due to the high reactivity, hydrophilic nature and relatively low costs associated with their monomer acrylamide .
- What is the maximum flocculation efficiencies of polyacrylamide?
- In general, the maximum flocculation efficiencies recorded for all polyacrylamide variants ranged from 94 to 100% for flocculant doses varying from 45 mg/L to 1.66 mg/L, respectively, for freshwater Chlorella vulgaris suspensions.
- Are polyacrylamide-based flocculants a viable alternative to physical harvesting methods?
- Compared to traditional physical harvesting methods, coagulation-flocculation techniques using polyacrylamide-based flocculants have garnered attention as promising alternatives due to their high harvesting efficiencies, cost-effectiveness, convenience, and scalability.
- Are polyacrylamide flocculants toxic?
- While most polyacrylamide flocculants are stable and non-toxic, some may leave behind acrylamide residues that are anticipated to be neurotoxic, potentially carcinogenic and generally exhibit high toxicity towards aquatic life .
