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

flocculants and coagulants: the keys to water and waste,the “art” of flocculation and coagulation has a lot more “science” than meets the eye. a variety of flocculants and coagulants is available, with different chemis-tries, molecular weights, charge ratios, and other attributes. it is critical that the appropriate flocculant and/or coagulant be chosen to ensure cost effective

What is a high molecular weight polyacrylamide (PAM)?
... High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
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 Pam degradation affect flocculant performance?
PAM-based flocculant degradation has been mainly studied for PAMs in aqueous solutions. The degradation of PAMs results in a reduction of the molecular weight of the polymer and can adversely affect the performance of such aqueous solutions in their commercial application as flocculants.
How do high molecular weight PAMS work as flocculants?
High molecular weight PAMs (10 6 to 10 7 g mol −1) work as flocculants by causing suspended particles to bind together to form larger aggregates, which can settle out quickly from solution leaving a clear supernatant (Heath et al. 2006 ).
