“…Other revisions have involved the sector as a whole, as [6,23]. According to [17], of the total energy consumed, 70% is used for operation and 30% for the construction. In North American WWTPs, due to the large volume of treated wastewater, 94% of the spent energy is in the plant's operating phase [23].…”

“…Reference [17] estimated consumption at 0.09 kWh/m 3 in India, or 45.3% of the total used for the WWTP operation. In the USA, the expenditure at this stage is 0.04 kWh/m 3 , in New Zealand it varies between 0.04 and 0.19 kWh / m 3 , in Canada it is around 0.02 and 0.1 kWh/m 3 [24], in Hungary it is between 0.045 and 0.14 kWh/m 3 , and in Australia it is estimated to be between 0.1 and 0.37 kWh/m 3 [21,25] suggested a global consumption average of 5 to 18% for pumping.…”

“…In Europe, in 2014, the primary energy produced from wastewater sludge biogas was 4.97x1013 kJ / year and in Spain, the estimate is 5.94x1012 kJ/year [40]. In a study by [17], the recovery of biogas in the WWTPs reduced the energy consumption by 33%, or 0.10 kWh/m 3 . Further research also indicates that the anaerobic digestion may generate 0.1 kWh / m 3 [3].…”

“…In the European Union, the energy and climate change strategy aims to transform the current resource-intensive economy model into a new sustainable growth model [16]. Ensuring energy and water security and reducing carbon emissions is important in the city planning [17]. Making a wastewater treatment plant (WWTP) self-sustaining in energy can improve its profitability [18] and reduce GHG emissions.…”

Abstract:Wastewater treatment is a process of intensive use of resources, mainly energy, which accounts for 15 to 40% of the operating costs in conventional wastewater treatment systems. With the expected demographic increase and the restrictive trend in quality standards for effluent discharge, the energy consumption tends to increase further if there are no changes in the processes. The literature gathers the energy consumption of different wastewater treatment systems, in an attempt to map the processes and to help the decision making in the search for better alternatives. One of these alternatives is the recovery of energy from the sewer. The conventional treatment system requires between 0.3 and 0.6 kWh/m 3 , while the energy contained in the wastewater may be up to 10 times of the one required for the treatment. The simultaneous wastewater treatment and power generation, called the hybrid treatment system, is a worldwide trend. In Brazil, recent studies have shown, through energy balances, the energy viability of anaerobic-aerobic systems, with the production of algae. This work presents a comparative review of the energy consumption of different wastewater treatment plants, aiming at a better understanding and management of the processes. The results showed that there are few Brazilian data published, indicating that the country still demands more studies on the subject to improve its processes. In the treatment of wastewater, most studies point to the aerobic process as the largest consumer of energy, and efforts are focused on the optimization of the conventional system, but still without great achievements. Environmental goals and water supply strategies are poorly integrated with the energy handling, leading to an inefficient use, and with economic and environmental consequences.

The energy-carbon-water (ECW) nexus has aroused increasing attention worldwide, as it is very important for sustainable development of socioeconomic systems. Researchers conducted a literature review of existing studies on the ECW nexus in terms of concepts, research focuses, mechanisms, and methodologies.Current research on the ECW nexus mainly focuses on the ECW flow accounting, the impact assessment of ECW-related policies or measures, and the description of the nexus characteristics. ECW-related measures may lead to a variety of cobenefits: economic growth, pollutant reduction, water quality improvement, and the carbon-water trade-off-that is, that the adoption of water-saving cooling technologies (such as wet cooling) could increase energy use and carbon dioxide (CO 2 ) emissions. ECW-related measures could also lead to the deployment of some lowcarbon power generation technologies, such as hydro, nuclear, and biofuel that could increase power sector water use. Nexus mechanisms of existing studies are mainly aimed at a specific sector; fewer studies consider the mechanisms from an economy-wide perspective. Integrated models, such as computable general equilibrium-based models and input-output (IO)-based hybrid life cycle assessment models, should be used to assess the broad socioeconomic impacts of ECWrelated measures in future, in order to inspire policymakers to design and implement effective measures for integrated ECW management.
