Aeration Settling Process on Treating ASP Produced Water of Oilfield

The concentration of suspended solid, oil, HPAM, surfactant, sulfide and silicate colloid was investigated by the simulation aeration and settling experiment. The major factors that influenced the content change of suspended solid were also determined in this study to provide reliable basis for the actual process.By the simulation experiment, the main influence factors that changed the concentration of suspended solid in ASP produced water were the precipitation of HPAM
