    2019-9-1 · Enhanced oil recovery using polymers such as polyacrylamide (PAM) to improve the sweep efficiency in the aqueous phase has been increasingly applied in offshore oilfields worldwide (Morel et al., 2012). A large amount of PAM remains in the produced wastewater, with PAM concentrations as high as 1900 mg/L (Standnes and Skjevrak, 2014).
