What is polyacrylamide (PAM)?

Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.

Is polyacrylamide a good soil conditioner?

However, as these solutions are proposed, numerous doubts and opposing opinions are emerging. Polyacrylamide (PAM), also known as “soil conditioner”, “soil amendment” and “soil stabilizer” in soil science (Gilda Dell'Ambrogio and Wong, 2019), is commonly used to modify the unfavorable and damaged characteristics of soil.

What is a non hydrolyzed polyacrylamide (PAM)?

Non-hydrolyzed polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) are frequently used in many industrial applications including waste water treatment processes (Guezennec et al. 2015), soil conditioning and erosion control (Levy and Warrington 2015), and oil and gas operations.

Can polyacrylamide be used as a soil stabilizing agent?

This chapter considers the potential of polyacrylamide (PAM, a synthetic organic polymer), as a soilstabilizing agent. Addition of PAM to aggregates at the soil surface leads to their stabilization and to improved bonding between adjacent aggregates that, in turn, improves soil physical and hydraulic properties.

Is a non-toxic acrylamide a good soil amendment?

Use of soil amendments such as a non-toxic anionic poly- acrylamide (PAM) has been shown to be beneficial for soil and water conservation and water quality (e.g. reviews by Sojka et al., 2006; Levy & Warrington, 2015 and cited refer- ences).

How dangerous is polyacrylamide (PAM)?

4.1.1. Polyacrylamide (PAM) As PAM is extensively used in our daily lives, it is essential to be aware of its potential hazards. Studies have indicated that PAM exhibits low or non-toxicity to humans, primarily due to the large sizes of polymers, which restrict their ability to penetrate the skin.
