“…Hence, although the cost per cubic meter of inlet water decreases, the same cost expressed in terms of cost per cubic meter of permeate increases, changing from just over 23 US$ per cubic meter of water generated in the process to nearly 27 US$ per cubic meter. This trend agrees with works published by Elsayed, N et al (2015) and Tavakkoli et al (2017). Fig.…”

“…Since high recycle ratios are needed to reach the outlet specified salinity and these streams must be reheated before entering the membrane stage again, the amount of thermal and pumping energy required increases dramatically. Similar findings were reported by Tavakkoli et al (2017), in whose study most of the operational cost was attributed to the thermal energy requirements.…”

Optimization of multistage membrane distillation system for treating shale gas produced water

Thermal membrane distillation (MD) is an emerging technology to desalinate highsalinity wastewaters, including shale gas produced water to reduce the corresponding water footprint of fracturing operations. In this work, we introduce a rigorous optimization model with energy recovery for the synthesis of multistage direct contact membrane distillation (DCMD) system. The mathematical model (implemented in GAMS software) is formulated via generalized disjunctive programming (GDP) and mixed-integer nonlinear programming (MINLP). To maximize the total amount of water recovered, the outflow brine is fixed close to salt saturation conditions (300 g·kg -1 water) approaching zero liquid discharge (ZLD).A sensitivity analysis is performed to evaluate the system's behavior under different uncertainty sources such as the heat source availability and inlet salinity conditions. The results emphasize the applicability of this promising technology, especially with low steam cost or waste heat, and reveal variable costs and system configurations depending on inlet conditions. For a produced water salinity ranging from 150 g·kg -1 water to 250 g·kg -1 water based on Marcellus play, an optimal treating cost are between 11.5 and 4.4 US$ m -3 is obtained when using low-cost steam. This cost can decrease to 2.8 US$ m -3 when waste heat from shale gas operations is used.

“…The average freshwater production by the proposed MD system was evaluated up to 40,759 L/day with a cost of $0.392/m 3 . The authors of [176] evaluated the economic feasibility of MD for wastewater treatment by performing a techno-economic assessment (TEA) for a hypothetical 0.5 million gallons per day (MGD) direct contact MD (DCMD) which concentrates produced water from 10% (100,000 mg/L) TDS to 30% salinity. Sensitivity analysis showed that the TDS level of the feed and the price of thermal energy significantly affect the total cost of treating produced water.…”

The scarcity of freshwater has been recognized as one of the main challenges people must overcome in the 21st century. The adoption of an environmentally friendly, cost-effective, and energy-efficient membrane distillation (MD) process can mitigate the pollution caused by industrial and domestic wastes. MD is a thermally driven process based on vapor–liquid equilibrium, in which the separation process takes place throughout a microporous hydrophobic membrane. The present paper offers a comprehensive review of the state-of-the-art MD technology covering the MD applications in wastewater treatment. In addition, the important and sophisticated recent advances in MD technology from the perspectives of membrane characteristics and preparation, membrane configurations, membrane wetting, fouling, and renewable heat sources have been presented and discussed.

This study explored the techno-economic feasibility of using membrane distillation to recover clean water from acid mine drainage employing both renewable and nonrenewable energy sources. A microporous hydrophobic polypropylene membrane displaying 0.45 um pores exhibited the highest water flux during long-term testing under steady state continuous process conditions. Currently, natural gas and electricity are the most economical energy sources for the proposed membrane separation process to treat acid mine drainage. However, by 2030 renewable sources, and PV in particular, will become competitive with nonrenewable energy sources.
