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

Abstract

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.

Forward Osmosis Application in Manufacturing Industries: A Short Review

“…Investigation of forward osmosis application ranges from lab-scale experiments (with either synthetic or real water) to full-scale implementation (with real water) and covers many fields, including: seawater desalination to produce drinking water [ 62 , 63 , 64 ], emergency water supply with so-called hydration bags [ 78 ], treatment of wastewater from oil and gas production as well as from mining [ 34 , 79 , 80 , 81 , 82 ], agricultural use for fertigation [ 83 , 84 , 85 ], biological wastewater treatment with osmotic membrane bioreactors [ 37 , 86 , 87 , 88 , 89 ], treatment of anaerobic digester centrate [ 90 , 91 ], microbial fuel cells [ 92 , 93 , 94 , 95 , 96 , 97 , 98 ], removal of trace organic compounds [ 99 , 100 , 101 , 102 , 103 , 104 ]. …”

Biodegradation of cellulose triacetate and polyamide forward osmosis membranes in an activated sludge bioreactor: Observations and implications

“…In addition, the initial rearrangement of the polymeric matrix of the membrane active skin layer may also contribute to the observed flux decline. It has been reported that the reverse salt flux could increase the ionic strength within the interface between the membrane active layer and the feed solution, reducing the electrostatic repulsion among CTA polymer chains and thereby compacting the membrane active layer [43].…”

Sustainable Water Reclamation from Different Feed Streams by Forward Osmosis Process Using Deep Eutectic Solvents as Reusable Draw Solution

“…The market for forward osmosis is growing rapidly owing to the extraordinary progress being made in the fields of membrane development, − draw solution, − and process design. , Despite the high number of publications and patents being filed in the niche of FO, there are only a limited number of reports which deals with the overall process, i.e., recovery and the quality of final potable/reusable water, ,, with robust FO membranes developed by HTI, Albany, U.S.A. being utilized in most of the FO research works and pilot plants. ,, Further with the pioneering work by Modern Waters & Oasys Water Inc. in developing the process and technology at commercial scale, FO is now competing with other technologies in both seawater desalination and wastewater treatment …”
