“…Considering the inevitable use of such resources in industries, water and energy use have obligatory interdependencies. Such interdependencies are encompassed in the concept of the water-energy nexus [3][4][5][6]. The improvement of energy efficiency in industries has been a subject of study by several authors (namely regarding the identification and analysis of improvement measures [7][8][9][10], their application into industrial processes factories [11] and the optimization of single equipment [12]).…”

Review on Water and Energy Integration in Process Industry: Water-Heat Nexus

2022

The improvement of water and energy use is an important concern in the scope of improving the overall performance of industrial process plants. The investment in energy efficiency comprehended by the most recent sustainability policies may prove to be an effective response to the fall of energy intensity rates associated with the economic crisis brought by the COVID-19 pandemic. The improvement in water efficiency may also prove to be a potential approach due to its interdependencies to energy use, whose exploitation comprises part of the study of the water-energy nexus. Waste heat recovery and water reclamation practices have been exploited to improve water and energy efficiency. A specific method designated “Combined Water and Energy Integration” has been applied to water recycling as both an additional water source and a heat recovery source in a set of water-using processes. In scientific and industrial domains, there is still a need for integrated approaches of water-using and combustion-based processes for overall water and energy efficiency improvements in industrial plants. In this work, an innovative approach for a simultaneous improvement of water and energy use is proposed based on process integration and system retrofitting principles. This proposal is based on the delineation of two innovative concepts: Water and Energy Integration Systems (WEIS) and Water-Heat Nexus (WHN). A review on existing technologies for waste heat recovery, thermal energy storage and heat-driven wastewater treatment is performed, following a conceptualisation design.

“…The work of Gregory N. et al [34], which deals with the projection of sustainability through the prism of intersectoral legislation at the government level, is noteworthy since it relates to our own issues. Interest in the water-energy nexus, a theory that describes how these two resources are connected, has grown along with worries about energy security and water scarcity.…”

This study deepens and further concretizes an analysis conducted in a prior study highlighting Romania’s goals and objectives in comparison with the sustainable development principles established through the adoption of the European Green Deal (EGD) at the European Union (EU) level. The second section of this paper presents this study’s methodology, aiming to highlight the quantification of the compatibility of the targets of Romania’s pertinent strategies with the EGD after evoking the principles of sustainable development (SD) and—in this context—the importance of achieving the objectives set by the EGD. The third section of this paper presents our findings, and the final section offers conclusions drawn from our analysis.

“…Despite their interconnection, water and energy tended to be studied and managed independently until Dr. Peter H. Gleick demonstrated an intrinsic relationship between these two resources in the 1990s, developing the concept that is known as the "water-energy nexus" [8]. Scientific and technological developments have since confirmed the close interrelation between the water and energy sectors [9][10][11].…”

Water-Energy Nexus: A Pathway of Reaching the Zero Net Carbon in Wastewater Treatment Plants

et al. 2020

View full text Add to dashboard Cite

The water-energy nexus, together with the need for sustainable management of these interconnected resources, has attracted growing attention from the scientific community. This paper focuses on this nexus from the point of view of the energy that is required by wastewater treatment plants, which are intensive energy consumers and major emitters of greenhouse gases. The main objective of the study is to investigate the possible use of a wastewater plant’s internal chemical, potential, and kinetic energy, and the addition of external renewable technologies with a view to achieving clean energy consumption and reducing greenhouse gas emissions. For this purpose, an analysis is made of the feasibility of introducing alternative technologies—anaerobic digestion, hydraulic turbines, wind turbines, and photovoltaic modules— to meet the plant’s energy needs. The plant chosen as case study (Jinamar plant, Canary Islands, Spain) has an energy consumption of 2956 MWh/year, but the employed methodological framework is suitable for other plants in locations where the renewable energy potential has previously been analyzed. The results show that a renewable energy production of 3396 MWh/year can be obtained, more than enough to meet plant consumption, but also confirm the need for an energy storage system, due to seasonal variability in energy resource availability. In terms of climate change mitigation, the emission of 2754 tons/year of greenhouse gases is avoided. In addition, the economic viability of the proposed system is also confirmed.
