“…Higher RSF values were observed for shale gas FPW as the FS than DI water, regardless of membrane orientations (Figure A,B). Similar phenomena have been reported using CTA membranes when DI water was replaced by oily wastewater or NaCl solution as the FS. − These were probably due to the reduction in dilutive external concentration polarization (ECP) or ICP and an increase in solute–solute interactions. On the one hand, compared to DI water, shale gas FPW as the FS has a lower water flux and less dilutive ECP (AL-DS mode) or dilutive ICP (AL-FS mode); thus, when DI water was replaced with shale gas FPW, the increased osmotic pressure in the FS may be masked by the marked decrease in dilutive ECP or ICP, reducing higher concentration gradient of draw solutes and hence higher RSF.…”

Fertilizer drawn forward osmosis (FDFO) was proposed to extract fresh water from flowback and produced water (FPW) from shale gas extraction for irrigation, with fertilizer types and membrane orientations assessed. The draw solution (DS) with NH 4 H 2 PO 4 displayed the best performance, while the DS with (NH 4 ) 2 HPO 4 resulted in the most severe membrane fouling. The DS with KCl and KNO 3 led to substantial reverse solute fluxes. The FDFO operation where the active layer of the membrane was facing the feed solution outperformed that when the active layer was facing the DS. The diluted DS and diluted FPW samples were used for irrigation of Cherry radish and Chinese cabbage. Compared to deionized water, irrigation with the diluted DS (total dissolved solid (TDS) = 350 mg• L −1 ) promoted plant growth. In contrast, inhibited plant growth was observed when FPW with high salinity (TDS = 5000 mg•L −1 ) and low salinity (TDS = 1000 mg•L −1 ) was used for irrigation of long-term (8-week) plant cultures. Finally, upregulated genes were identified to illustrate the difference in plant growth. The results of this study provide a guide for efficient and safe use of FPW after FDFO treatment for agricultural application.

“…This is in line with Hannibal and Portney's [52] findings that the nexus research, or the connection between water, energy and food, has not been sufficiently addressed in the social sciences. Field experiments were only employed by 4% of the studies, namely, Mortensen et al [53] on nutrient loops in arid-land rivers, Obade and Lal [54] on soil quality assessment, and Tran et al [55] on the suitability of a sulfur-based seed solution in the development of WEF nexus technology using sulfur chemicals that contain an air pollutant. These results prove that the WEF concept is starting to be operationalized in research.…”

Irrigated agriculture is essential to satisfying the globally increasing demand for food and bio-based products. Yet, in water scarce regions, water-use for irrigation aggravates the competition for the use of water for other purposes, such as energy production, drinking water and sanitation. Solutions for sustainable food production through irrigated agriculture require a systemic approach to assess benefits and trade-offs across sectors. Here, the water–energy–food (WEF) nexus has become an important concept in natural resource management. It has been conceptualized to analyze linkages and trade-offs between the three sectors, across temporal and spatial scales. However, the concept has so far mainly been conceptual, with little empirical evidence or proof of concept in real world cases. The objective of this paper was to take stock of the rapidly advancing literature on the WEF nexus in irrigated agriculture, and to analyze how the concept was actually implemented in research studies, and how the nexus between water, food and energy was actually dealt with. The study period ranges from 2011 to 2019, and includes 194 articles. Results showed that the WEF nexus is indeed very relevant in irrigated agriculture, and the respective literature makes up one third of all WEF nexus papers. Modeling and empirical research have caught up with conceptual synthesis studies during the last four years, thereby indicating that the WEF nexus concept is indeed increasingly operationalized. However, most studies addressed the WEF nexus from a perspective of either socioeconomic, technological or environmental categories, and they place one of the dimensions of water, food or energy into the foreground. To address sustainable development, there is a need to fully integrate across research disciplines and thematic dimensions. Such studies are only starting to emerge. These findings are an important evidence-base for future WEF nexus research on irrigated agriculture, in support of sustainable solutions for water scarce regions, especially in settings undergoing transformations.

“…This was the concept of the fertiliser-driven FO (FDFO) process, which was primarily applied for agricultural purposes via fertilised irrigation, or fertigation, wherein the fertilisers are supplied through an irrigation network system. While this process has yet to be fully commercialized, the concept of FDFO has since been the subject of a number of extensive work on fertigation, osmotically-driven processes, and hydroponics [14][15][16][17][18][19][20][21][22][23].…”

GreenPRO: A novel fertiliser-driven osmotic power generation process for fertigation

et al. 2018

This study introduces and describes GreenPRO, a novel concept involving fertiliserdriven osmotic energy generation via pressure retarded osmosis (PRO). The potential of GreenPRO was proposed for three objectives: (a) power generation, (b) water pressurization for fertiliser-based irrigation, and (c) water treatment, as a holistic water-energy-food nexus process. Three pure agricultural fertilisers and two commercial blended fertiliser solutions were used as the draw solution and irrigation water as feed to test this concept for power generation.Theoretical thermodynamic simulation of the maximum extractable Gibbs energy, was first performed. After which, a series of bench-scale experiments were conducted to obtain realistic extractable energy data. The results showed that concentrated fertilisers potentially have 11 times higher energy than seawater. Even after accounting for the irreversibility losses due to constant pressure operation, the investigated pure fertilisers were found to have between 2.5 -4.6 Wh/kg of energy. The outcomes from the flux and power density modelling were then validated with real experimental data. This study has successfully demonstrated that concentrated fertilisers can release a substantial amount of chemical potential energy when diluted for fertigation. This energy could be harnessed by transforming it into electric energy or pressure energy via PRO.
