Guezennec et al. (2015) studied the polyacrylamide transfer and degradation in hydrosystems. Mclaughlin and Bartholomew (2007) presented the soil factors influencing the flocculation process
Degradation and transfer of polyacrylamide based
The polyacrylamide was not much studied, essentially focusing on its degradation mechanism. The risk associated with polyacrylamide use is then an important factor to understand. The scientific knowledge in this domain is too much limited to be able to assess the environmental impact of these products in this specific context.
Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed. Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation.
Polyacrylamide degradation and its implications
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

Polyacrylamide(flocculant)used for Drinking water
Polyacrylamide(flocculant)used for Drinking water treatment. Drinking water grade PAM is mainly be used in raw water treatment,sugar making,fermentation,etc.PAM can be added in raw water for the purpose of settling and flocculating,which can effectively reduce the additive quantity of poly-aluminum, thus avoiding producing too much sludge.
The formation of fouling on an AEM will be affected by the composition of the solution, which includes various dissolved salts, partially hydrolyzed polyacrylamide (HPAM), crude oil, and surfactants.
- What are flocculants used for?
- Flocculants, usually composed of PAMs, 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 residual monomer of acrylamide (AMD), which is known to be a toxic compound.
- Can flocculant be used for wastewater treatment?
- The first two photos indicate reaction components, whereas the last SEM image depicts the result. Flocculant, in addition to displaying good flocculation performance, has also shown success in eliminating ammonia, nitrogen, iron, and phosphorus. These findings suggest that this flocculant is ideal for many wastewater treatment applications.
- What is a flocculant program?
- Flocculant Program Provides Significant Benefits to a Nickel Processing Plant Dealing with Difficult to Process Ores Solenis offers a complete portfolio of emulsion, powder and water-based flocculants for water treatment and process treatment applications.
- How much PAM based flocculants are consumed in France?
- In France, for instance, the consumption of PAM-based flocculants is about 15 kt year −1. In particular, the aggregate production uses about 900 t year −1 of PAM-based flocculants (i.e., 6 % of the total consumption) as clarification aid (UNPG 2013).
