Biodegradation of partially hydrolyzed polyacrylamide hpam using bacteria isolated from omani oil fields. In Society of Petroleum Engineers - SPE EOR Conference at Oil and Gas West Asia 2025 (Vol. 2025-March). Society of Petroleum Engineers.
Polyacrylamide (PAM) used in sludge dewatering widely exists in high-solid anaerobic digestion. Degradation of polyacrylamide accompanied with accumulation of its toxic monomer is important to disposition of biogas residues. The potential of anaerobic digestion activity in microbial utilization of PAM was investigated in this study.
Biodegradability enhancement of hydrolyzed polyacrylamide
1. Introduction. In the process of the exploitation of oil and nature gas, HPAM is widely used to raise oil or natural gas yield (McGuire et al., 2006, Zhao et al., 2025).However, the wastewater from the drilling process cannot be effectively treated because of its high COD and HPAM concentrations, these wastes, especially the residual HPAM, often causes a great threat to human health and

Biodegradation of Polyacrylamide and Its Derivatives
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.
At 8 months, there was little evidence of biodegradation. The implanted hyaluronic acid remained walled off from the surrounding tissue by a capsule consisting of collagen and fibroblasts. Minimal infiltration of cells into the implant was noted and there was no connective tissue formation within the implant. Inflammation was minimal.
Global Oilfield Polyacrylamide Market Segment Outlook
The global oilfield polyacrylamide market is segmented on the basis of type, application, and geography. The Global Oilfield Polyacrylamide market is estimated to be US$ XX.X Mn in 2025 and is projected to increase significantly at a CAGR of x.x% from 2025 to 2028. Oilfield Polyacrylamide Market Scope:
The use of composts and vermicomposts as adsorbents is an important topic of study in the field of environmental remediation. These materials are rich in organic matter and have functional groups that can interact with organic and inorganic compounds. They also contain microorganisms that can promote biodegradation of organic substances.

- Is acrylamide a monomer or a polymer?
- Indeed, monomers can be classified as more active monomers (MAMs), such as acrylamide or acrylates, and less active monomers (LAMs), such as N -vinylpyrrolidone or methacrylate. When considering acrylamide polymerization, the large amount of heat released (82.8 kJ·mol −1) results in a fast temperature rise .
- What is polyacrylamide (PAM)?
- Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
- Is polyacrylamide toxic?
- Studies have shown that polyacrylamide is harmless to the body, but the acrylamide monomer released from polyacrylamide contains toxins . The toxicity of acrylamide mainly includes neurotoxicity, reproductive toxicity, genetic toxicity, immunotoxicity, and potential carcinogenicity .
- What is polyacrylamide made of?
- Polyacrylamide is a polymer of controllable molecular weight formed by the polymerization of acrylamide monomers available in one of three forms: solid (powder or micro beads), aqueous solution, or inverse emulsions (in water droplets coated with surfactant and suspended in mineral oil).
