“…Hence, if a standard deviation of 30% is considered from the expected mean value of the salt concentration in the flowback water (80k ppm); ~95% of the data will be in the range of 32−128k ppm. Nevertheless, it should be highlighted that the brine discharge salinity should be at least equal to 300 g kg -1 (300k ppm) to achieve ZLD operation (Han et al, 2017).…”

“…The latter authors have used a finite differences-based method for the numerical simulation of the process, by allowing salt concentration in brine discharges near to saturation condition. On the other hand, Han et al (2017) have developed mathematical models for SEE and MEE-MVR processes simulations of ZLD seawater desalination. Through energy and exergy analyses, the authors have concluded that MEE are often more attractive than single-effect systems, due to lower compressor power consumption.…”

Sustainable and efficient desalination is required to treat the large amounts of highsalinity flowback water from shale gas extraction. Nevertheless, uncertainty associated with well data (including water flowrates and salinities) strongly hampers the process design task. In this work, we introduce a new optimization model for the synthesis of zero-liquid discharge (ZLD) desalination systems under uncertainty. The desalination system is based on multiple-effect evaporation with mechanical vapor recompression (MEE-MVR). Our main objective is energy efficiency intensification through brine discharge reduction, while accounting for distinct water feeding scenarios. For this purpose, we consider the outflow brine salinity near to salt saturation condition as a design constraint to achieve ZLD operation. In this innovative approach, uncertain parameters are mathematically modelled as a set of correlated scenarios with known probability of occurrence. The scenarios set is described by a multivariate normal distribution generated via a sampling technique with symmetric correlation matrix. The stochastic multiscenario non-linear programming (NLP) model is implemented in GAMS, and optimized by the minimization of the expected total annualized cost. An illustrative case study is carried out to evaluate the capabilities of the proposed new approach. Cumulative probability curves are constructed to assess the financial risk related to uncertain space for different standard deviations of expected mean values. Sensitivity analysis is performed to appraise optimal system performance for distinct brine salinity conditions. This methodology represents a useful tool to support decision-makers towards the selection of more robust and reliable ZLD desalination systems for the treatment of shale gas flowback water.Keywords: Shale gas flowback water; Multiple-effect evaporation with mechanical vapor recompression (MEE-MVR); Zero-liquid discharge (ZLD); Uncertainty; Risk management; Robust design.3

“…HDH systems were developed, with technical and economic considerations, for agricultural use and drinking water requirements in arid regions. These systems contain a humidifier and a dehumidifier, energy sources for heating and electrical energy generation as well as accessories for the fluid transfer and control devices [38][39][40]. The main crop requirements inside greenhouses in an HDH system are given in Table 2 [41,42].…”

Many countries in the MENA region (Middle East and North Africa) are facing water scarcity, which poses a great challenge to agricultural production. Furthermore, water scarcity is projected to increase due to climate change, particularly in arid and semi-arid regions. The integration of solar power and water desalination systems in greenhouses to overcome water shortages is one of the preferred technologies in crop-growing areas. Crop growth control is done through sufficient management of environmental climatic variables as well as the quantity and quality of water and applied fertilisers with irrigation. Numerous crops such as cucumbers, tomatoes, peppers, lettuces, strawberries, flowers, and herbs can be grown under greenhouse conditions using desalinated water. This paper displays the state of the art in (i) solar-driven saltwater desalination to irrigate crops, (ii) the feasibility of water desalination for agriculture in the MENA region, (iii) the economics and environmental impacts of the desalination process, (iv) the quality of desalinated water compared with other non-conventional water resources and (v) recommendations for the future in the MENA region.
