Comparative study of NF and RO membranes in the treatment of produced water—Part I: Assessing water quality

Evaluation of the transport parameters and physiochemical properties of forward osmosis membranes after treatment of produced water

“…An FO transport and structural parameter model [20] and containment rejection data collected during membrane exposure tests support the findings of this investigation. The results of this study can help guide future investigations on the performance and sustainability of polymeric membranes for produced water 3 and the modeled structural parameter (S) of the three membranes were determined using methodologies developed by Tiraferri et al [20]. The A, B, and S coefficients for each membrane were similar to those reported in our previous study [9], which employed membranes from the same casting.…”

“…This is especially true in the oil and gas industry, where rapid oil field exploration has spurred the development of tight-barrier membrane processes for treatment of wastewaters like hydraulic fracturing flowback and produced waters [3][4][5][6][8][9][10][11][12][13][14][15]. While exceedingly higher total dissolved solids (TDS) concentrations in produced water has been a traditional hurdle for a variety of water treatment technologies, the prevalence of dissolved organic and aromatic compounds in oil field wastewaters has gained significant attention [16][17][18][19][20][21].…”

“…The application of semipermeable polymeric membranes for dewatering of complex feed streams, and especially those laden with a variety of organic compounds and hydrocarbons, has increased in recent years [1][2][3][4][5][6][7][8]. This is especially true in the oil and gas industry, where rapid oil field exploration has spurred the development of tight-barrier membrane processes for treatment of wastewaters like hydraulic fracturing flowback and produced waters [3][4][5][6][8][9][10][11][12][13][14][15].…”

Influence of salts, anion polyacrylamide and crude oil on nanofiltration membrane fouling during desalination process of polymer flooding produced water

“…Their results demonstrated that this technology could effectively meet water standards for polymer flooding and ensure stable oil production. Many researchers [18][19][20][21][22] purified produced water with various NF and RO membranes aiming for water reuse, confirming the feasibility of this technical process. Based on the facts above, it is highly expected to adopt NF to realize PFPW reuse for polymer flooding extraction.…”

Advanced treatment of municipal wastewater by nanofiltration: Operational optimization and membrane fouling analysis

“…It is well known that NF can effectively remove multivalent ions and high molecular weight organic compounds with lower operating pressure and higher permeate flux in comparison with RO. Thus, NF is a promising technology for advanced wastewater treatment considering its energy requirements and cost effectiveness, particularly when both NF and RO are suitable for wastewater reclamation (Alzahrani et al, 2013;Shahmansouri and Bellona, 2015). Despite these advantages, membrane fouling is still a key issue that hinders the application of membrane technologies.…”
