What is biodegradation of partially hydrolyzed polyacrylamide?

Biodegradation of partially hydrolyzed polyacrylamide by bacteria isolated from production water after polymer flooding in an oil field Critical perspective on advanced treatment processes for water and wastewater: AOPs, ARPs, and AORPs

What is partially hydrolyzed polyacrylamide (HPAM)?

Partially hydrolyzed polyacrylamide (HPAM) is one of the most popular polymer used owing to strong thickening effect and good solubility ( Gao, 2013; Samanta et al., 2013 ). It was reported the content of HPAM in the produced wastewater ranged in 200–630 mg/L ( Li et al., 2021).

Does polyacrylamide improve oil recovery?

Introduction Polyacrylamide has been widely used in oilfields to enhance oil recovery ( Pogaku et al., 2018 ).

How are polyacrylamides treated?

The top left is the filter, the top right is the reservoir, and bottom left and bottom right are settling tanks. Polyacrylamides are typically addressed through various treatment methods, including membrane filtration, thermal distillation, oxidation treatment, and biological removal (Table 2).

What is partially hydrolyzed polyacrylamide (PHPA)?

Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.
