“…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].…”

“…The organic compounds present in feed streams like produced water exhibit a wide range of physiochemical properties and concentrations; however, their potential effects on membrane performance and sustainability is not yet clear. The effects of produced water and organic compound exposure on the properties of pressure driven membranes (e.g., water permeability, contaminant rejection, and membrane surface characteristics) has only been briefly investigated [7,22].…”

Evaluation of the transport Parameters and physiochemical properties of forward osmosis Membranes after treatment of produced water, Journal of Membrane Science, http://dx. AbstractThe application of semipermeable membranes for dewatering of complex oil and gas wastewaters continues to be a topic of increasing interest. Several studies have explored the fouling propensity and contaminant rejection of osmotically driven membranes during forward osmosis (FO) treatment of produced waters; however, none have investigated changes in membrane transport and physiochemical properties after exposure to these feed streams. In this study we discuss the impacts of produced water exposure on the transport and active layer surface properties of cellulose triacetate (CTA) and polyamide thin-film composite (TFC) FO membranes. While produced water exposure yields some, albeit minor, changes to the membrane performance and surface characteristics of the CTA and the traditional TFC membranes, close to 50% reduction in reverse salt flux and contaminant transport was observed for a surface-modified TFC FO membrane; only minimal changes in water permeability were recorded. Results of this study demonstrate the chemical and physical robustness of FO membranes for treatment of oil and gas wastewaters, and they highlight a knowledge gap that exists in membrane polymer selection and contaminant interactions with the membrane polymer matrix that should be further addressed in future membrane fouling studies.
