Production, Characterization, and Flocculation Mechanism
Between 200–300 µm flocs were formed by the ETH-2 strain when tested for kaolin clay flocculation (Figure 7b), indicating its advantage on flocculation. The purified bioflocculant ETH-2 also formed 100–200 µm flocs during kaolin clay flocculation testing (Figure 7c), larger than flocs formed by Bacillus megaterium TF10 (20–30 µm) .

Intrinsic viscosity, surface activity, and flocculation
The polymer exhibited good surface activity in both water and salt solution. Its flocculation properties were evaluated with kaolin suspensions using a standard jar test. The results demonstrated the superiority of the copolymer over the no-modified cationic polyacrylamide as a flocculant.
The fabrication of a cationic polyacrylamide (CPAM) with high efficiency and economy has been highly desired in the field of high-turbidity water treatment. polyacrylamide (PAM) made in the laboratory was used for the characterization analysis. 2.2. Synthesis of copolymers The FTIR analysis of the kaolin flocs that formed confirmed that
- Is polyacrylamide a good thickening agent for EOR?
- Polyacrylamide (PAM) Polyacrylamide is a renowned thickening agent for EOR applications. This is because of its high molecular weight (>1 × 10 6 g/mol). In its unhydrolyzed form, PAM is nonionic in nature (see Figure 8). Hence, high adsorption of the polymer on mineral surfaces is prevalent. This limits its direct application for chemical EOR.
- Can polyacrylamide be used as a thickener in water-based fracturing fluids?
- Polyacrylamide (HPAM) is commonly used as a thickener in water-based fracturing fluids due to its good solubility and thickening ability. However, drawbacks such as the formation of high temperature and high salinity in oil and gas production currently limit its use as a thickening agent for fracturing fluids.
- Can polyacrylamide improve hydrocarbon production efficiency?
- npj Materials Sustainability 2, Article number: 15 (2025) Cite this article Polyacrylamide (PAM) and its derivatives play a pivotal role in various facets of hydrocarbon development. Proper application and treatment of PAM have the potential to enhance hydrocarbon production efficiency while mitigating adverse environmental effects.
- What is high molecular weight polyacrylamide (PAM)?
- Provided by the Springer Nature SharedIt content-sharing initiative 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.
