“…Thus, the membrane is not selective and the separation is based on the phase equilibrium [35]. Examples of hypertonic solutions can be the brines obtained from integrated membrane desalination systems, reaching concentrations higher than 250 g/L of salt [36], of which the recovery and/or reuse is subject of further study [37][38][39][40]. In addition, the porous surface of the membrane induces heterogeneous nucleation (formation of nuclei locally close to the surface) while the crystal growth can be produced in a separate place.…”

“…ED is more cost effective than RO in the salinity range of 1.5-5 g/L [18] and has the potential to treat the waste stream generated by pressure driven membrane processes, which are commonly used in desalination and water reuse applications. Such waste streams, or brines, contain salts, nutrients, organic matter (OM) and numerous micropollutants including pesticides, heavy metals, endocrine disrupting chemicals [19].…”

Endosulfan (ES) is a micropollutant found in reverse osmosis concentrates from water reuse applications. Electrodialysis (ED) can remove and recover charged solutes from such concentrates.While polar compounds cannot normally be removed, their fate in ED is important as they can contribute to membrane fouling/poisoning and be released during cleaning. High adsorption of ES to ED membranes was observed. Consequently, the influence of solution pH and presence of humic acid (HA) on sorption mechanisms of ES to ion-exchange membranes during batch sorption isotherm and ED experiments were investigated systematically. ES-membrane partition coefficients * Current address: Faculty of Engineering, University of Wollongong, Wollongong NSW 2522, Australia 2 (log K AEM/CEM ) quantified through sorption isotherm experiments suggested that ES sorption was resultant of membrane catalysed ES degradation, hydrogen bonding and cation-π interactions between ES and membrane functional groups. ES sorption at pH 7 (550 µg/cm 3 ) was greater than sorption at pH 11 (306 µg/cm 3 ) due to alkaline hydrolysed ES and resultant decrease in bonding capacity with the membranes at high pH. The presence of HA reduced sorption at pH 7 (471 µg/cm 3 ) and 11 (307 µg/cm 3 ) due to HA competitive sorption. Partial membrane desorption was noted in isotherm (≤ 20%) desorption experiments and was dependent on the initial mass sorbed, solvent pH and resultant membrane interactions.

“…In addition to their low capital cost, evaporation ponds have the potential to be combined with salt recovery, mineral harvesting, solar ponds for electricity generation, and saline aquaculture including: fish, brine shrimp, and algae growth for biofuels or for beta carotene production (Ahmed et al 2003;Van Der Bruggen et al 2003). In these cases, the saline effluent is converted from a waste to a resource.…”

Assessment of Brine Management for Geologic Carbon Sequestration

Geologic carbon sequestration (GCS) is the injection of carbon dioxide (CO2), typically captured from stationary emission sources, into deep geologic formations to prevent its entry into the atmosphere. Active pilot facilities run by regional United States (US) carbon sequestration partnerships inject on the order of one million metric tonnes (mt) CO2 annually while the US electric power sector emits over 2000 million mt--CO2 annually. GCS is likely to play an increasing role in US carbon mitigation initiatives, but scaling up GCS poses several challenges. Injecting CO2 into sedimentary basins raises fluid pressure in the pore space, which is typically already occupied by naturally occurring, or native, brine. The resulting elevated pore pressures increase the likelihood of induced seismicity, of brine or CO2 escaping into potable groundwater resources, and of CO2 escaping into the atmosphere. Brine extraction is one method for pressure management, in which brine in the injection formation is brought to the surface through extraction wells. Removal of the brine makes room for the CO2 and decreases pressurization. Although the technology required for brine extraction is mature, this form of pressure management will only be applicable if there are cost--effective and sustainable methods of disposing of the extracted brine.Brine extraction, treatment, and disposal may increase the already substantial capital, energy, and water demands of Carbon dioxide Capture and Sequestration (CCS). But, regionally specific brine management strategies may be able to treat the extracted water as a source of revenue, energy, and water to subsidize CCS costs, while minimizing environmental impacts. By this approach, value from the extracted water would be recovered before disposing of any resulting byproducts. Until a price is placed on carbon, we expect that utilities and other CO2 sources will be reluctant to invest in capital intensive, high risk GCS projects; early technical, economic, and environmental assessments of brine management are extremely valuable for determining the potential role of GCS in the US.We performed a first order feasibility and economic assessment, at three different locations in the US, of twelve GCS extracted--water management options, including: geothermal energy extraction, desalination, salt and mineral harvesting, rare--earth element harvesting, aquaculture, algae biodiesel production, road de--icing, enhanced geothermal system (EGS) recharge, underground reinjection, landfill disposal, ocean disposal, and evaporation pond disposal. Three saline aquifers from different regions of the US were selected as hypothetical GCS project sites to encompass variation in parameters that are relevant to the feasibility and economics of brine disposal. The three aquifers are the southern Mt. Simon Sandstone Formation in the Illinois Basin, IL; the Vedder Formation in the southern San Joaquin Basin, CA; and the Jasper Interval in the 3 eastern Texas Gulf Basin, TX. These aquifers are candidates for GCS due ...
