Application of polyacrylamide flocculants for water treatment
Polyacrylamide (PAM) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. The accumulation of PAM affects the formation of dewatered sludge and potentially produces

The Use of Cationic Polymers as Primary Coagulants
In applying organic polymers to the removal of UV absorbing compounds (used as a measure of trihalomethane precursors), a reservoir water was best treated with a high MW polydiallyldimethy-lammonium chloride (poly DADMAC). Similar results were obtained for a river water, where a cationic polyacrylamide (CPAM) of high charge was also effective.
These cationic flocculants are also offered in a range of molecular weights. This enables the customer to select the optimum polymer depending on application needs, such as low molecular weights for low shear applications (e.g. gravity belt thickener) to very high molecular weights for high shear environments (e.g. centrifuge decanters).
Polyacrylamide degradation and its implications
High MW anionic PAM is also the most commonly applied polymer in enhanced oil recovery applications; the use of surfactant-polymer flooding can increase oil recovery by 5–30% 14 and in some
mide with a cationic monomer, cationically modified acrylamide or a polyamine. The cationic charge in these polymers is derived from nitrogen in the form of a secondary, tertiary or quaternary amine group. Those containing secondary or tertiary amines are sensitive to pH, and the charge on these polymers drops off at a pH >6.0.

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. 1,9,12,21
cationic polymer in water treatment
Dissolved organic nitrogen removal during water treatment . However, polymer addition alone also removed more DON in Harwood Reservoir water. Since the polymer addition does not affect the pH of water samples (the cationic polymer solution had a neutral pH) and cationic polymer is a dominant positive charge contributor, the positive charge doses on these two waters were almost the same.

- What is water soluble anionic polyacrylamide (PAM)?
- Water soluble anionic polyacrylamide (PAM) was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1–10 g m −3 in furrow irrigation water. Water flowing from PAM treated irrigation furrows show large reductions in sediment, nutrients and pesticides.
- What is anionic polyacrylamide (PAM)?
- Volume 224, article number 1382, ( 2013 ) Anionic polyacrylamide (PAM) is a linear, water-soluble anionic polymer that is widely used for erosion control and water quality protection.
- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 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.
- Can anionic polyacrylamide (PAM) be used to treat animal waste?
- The application of anionic polyacrylamide (PAM) to soils and/or vegetative treatments may also provide a cost-effective way to dramatically reduce bacteria and nutrient loads in animal waste effluent and thereby reduce pollution in surface and ground waters receiving these effluents.
