Performance evaluation of a submerged membrane bioreactor for the treatment of brackish oil and natural gas field produced water

The biodegradation of petroleum hydrocarbons in an upflow sludge-blanket/fixed-film hybrid bioreactor under nitrate-reducing conditions: Performance evaluation and microbial identification

“…The treatment of oilfield-produced water was evaluated in a membrane-coupled sequencing batch reactor, and 91.5% of oil and grease (O&G) was obtained at an inlet loading rate of 31.2 g/m 3 .h O&G [13]. Kose et al [31] reported a TPH removal level between 82% and 99% when treating a produced water contacting TPH at concentrations of 1030 and 2210 mg/L in a submerged aerobic membrane bioreactor. A membrane sequencing batch reactor was evaluated for treating a synthetically produced water, and a 98.8% O&G removal rate was detected at a hydrocarbon loading rate of 17 g/m 3 h [3].…”

Performance of a moving bed-membrane bioreactor treating saline wastewater contaminated by hydrocarbons from washing of oil tankers

“…However, in marine environment with high salt concentration (10-30 g L −1 of NaCl), slightly halophilic bacterial strains can be selected [6,8]. Furthermore, as the biological removal of TPHs is uncertain due to a toxic effect towards bacteria [4,9], a biomass acclimation is required before any biological treatment [10]. An increasing interest in the use of membrane bioreactor (MBR) technology has been expressed in the last decades, especially for the treatment of saline wastewaters [6,7,11] and for high salinity wastewater contaminated by hydrocarbons [4,10].…”
