“…High-salinity brines are generated from a variety of industrial sources, including flowback and produced water from oil and gas extraction, 1−3 waste effluents from thermoelectric power plants, 4,5 and discharges of coal-to-chemicals facilities. 6,7 Other prominent examples are concentrates from inland brackish water desalination and landfill leachate treatment.…”

Zero liquid discharge (ZLD) of hypersaline brines is technically and energetically challenging. This study demonstrates ZLD of ultrahigh-salinity brines using temperature swing solvent extraction (TSSE), a membrane-less and nonevaporative desalination technology. TSSE utilizes a low-polarity solvent to extract water from brine and then releases the water as a product with the application of low-temperature heat. Complete extraction of water from a hypersaline feed, simulated by 5.0 M NaCl solution (≈292 g/L TDS), was achieved using diisopropylamine solvent. Practically all of the salt is precipitated as mineral solid waste and the product water contains <5% of NaCl relative to the hypersaline feed brine. Consistent ZLD performance of high salt removals and product water quality was maintained in three repeated semibatch TSSE cycles, highlighting recyclability of the solvent. The practical applicability of the technique for actual field samples was demonstrated by ZLD of an irrigation drainage water concentrate. This study establishes the potential of TSSE as a more sustainable alternative to current thermal evaporation methods for zero liquid discharge of ultrahigh-salinity brines.

“…Cleaning is also an important part of effective membrane plant fouling management. Typically in membrane processes, inorganic foulants can be removed by washing with product water or acid (hydrochloric or citric) leading to complete recovery of flux [36][37][38][39][40]. Partial reversal of organic fouling by humic substances has been shown using water and complete recovery was achieved with a subsequent clean with 0.1 M NaOH [41].…”

“…This is due to the potentially low fouling in MD compared to pressure-driven processes, ability to achieve a very high concentration factor, and excellent quality of the permeate obtained. The investigations carried out so far have mainly focused on the flux and fouling behavior (Jacob et al 2015), scaling issues (Yu et al 2013), and the effect of pretreatment on the process performance (El-abbassi et al 2013).…”

Direct contact membrane distillation for the treatment of wastewater for a cooling tower in the power industry

et al. 2018

Water abstraction for cooling requirements in energy production accounts for more than 40% of the total gross abstraction in the European Union, thus driving the interest in using alternative water resources. The current study presents the application of direct contact membrane distillation for the treatment of wastewater from a flue gas desulphurization (FGD) plant for potential applications in cooling towers. Membrane distillation (MD) performance of two commercial lab-scale membrane modules (in capillary and flat configuration) was compared in terms of flux, specific energy consumption (SEC), and rejection towards non-volatiles present in wastewater samples, pretreated according to various protocols. For the flat module, two commercial membranes were tested. In all cases, a good quality permeate was produced, with stable flux over experimental time. SEC of MD for wastewater treatment, calculated experimentally, varied from 946 to 2,830 kWh/m3 for the various applied membranes operating under different conditions. MD allows extracting more than 80% freshwater from FGD wastewater stream while maintaining high (>99.60%) rejection towards electrical conductivity.
