water treatment flocculation: which flocculation agent is best?
polyacrylamide is a polymer-based flocculant that is widely used in the treatment of water, ranging from waste water to drinking water. it is often used as an anionic — or negatively charged — flocculant and is popular in industry, thanks to its broad availability and relative safety when in use or in storage.
biopolymer-based flocculants a review of recent technologies,biopolymer-based flocculants have become a potential substitute for inorganic coagulants and synthetic organic flocculants due to their wide natural reserves, environmental friendliness, easy natural degradation, and high material safety. in recent years, with more and more attention to clean technologies, a lot of researches on the modification and application of biopolymer-based flocculants
polyacrylamide pam flocculant for water treatment with best quality
polyacrylamide pam, with the chemical formula of (c3h5no)n, is a linear polymer. polyacrylamide polymer has good thermal stability, can be dissolved in water in any proportion. and the aqueous solution is a uniform and transparent liquid. pam is one of the most widely used water-soluble polymers.
degradation of polyacrylamide and its significance in nature,the hydrolyzed form of polyacrylamide (hpam), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic pam in oil and gas development as well as in soil conditioning.

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

- What is polyacrylamide (PAM) used for?
- High molecular weight polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction reducer in enhanced oil recovery and high-volume hydraulic fracturing.
- Does anionic polyacrylamide improve coagulation-flocculation process?
- Use of anionic polyacrylamide as a coagulant to improve the coagulation-flocculation process. High molecular weight hydrolyzed polyacrylamide.
- How do polyelectrolytes promote flocculation?
- Polyelectrolytes are available as various grades on basis of molecular weights, charge densities, and hydrolysis values. Polyelectrolytes are capable of promoting flocculation by neutralising the electric charges of suspending particles in the water and unstabilizing the particles.
- Does Pam solvated with Fe 3+ release acrylamide?
- It was found that PAM solvated with Fe 3+ generated ppb levels of acrylamide after exposure to sunlight under acidic conditions (pH 6). They concluded that release of acrylamide would be insignificant at low levels of iron (0.02 mg/L) under alkaline (7.5–8.5) conditions.
