Water Pinch

Fuel ethanol is considered to be a clean alternative fuel to meet increasing energy demands and mitigate environmental pollution. Faced with challenges in terms of energy security and environmental pollution, China is vigorously developing fuel ethanol. However, ethanol-manufacturing is a water-intensive industry; it consumes large volumes of fresh water and generates a corresponding amount of waste water. Expansion of this industry can reduce water quality and cause water stress. This study aims to combine the water footprint (WF) with a water pinch analysis technique to manage water consumption and sewage discharge systematically in an ethanol plant. A well-operated cassava ethanol plant in China was chosen as a case study. The WF of industrial ethanol production was evaluated. The total WF was 17.08 L/L ethanol, comprised of a 7.69 L blue water footprint (BWF), and a 9.39 L gray water footprint (GWF). The direct WF was 16.38 L/L ethanol, and the indirect WF was 0.70 L/L ethanol. Thereafter, a water pinch analysis was conducted, and the optimal direct water reuse scheme was studied. After the water network was optimized, the BWF was reduced by 0.98 L/L ethanol, while the GWF was reduced by 1.47 L/L ethanol. These results indicate that the combined use of WF and pinch analysis can provide the starch-based ethanol industry with an effective tool to improve its water management.

The United Nations Brundtland Commission defined sustainability as “meeting the needs of the present without compromising the ability of future generations to meet their own needs.” In the context of this definition, sustainable water management should encompass current management of water resources as well as its potential effect on the future. Sustainable water management in oil and gas is a journey that will need approaches from many perspectives. The highlighted papers illustrate the different perspectives and accompanying complexities that can advance progression toward more-sustainable water management. The approaches are multi-faceted in that they consider technological, environmental, economic, and social needs and responsibility. The papers include issues and challenges in reuse/recycling of produced water, new guidelines to standardize application of risk-based assessments to assess potential environmental impact from produced-water discharge, and a novel certification process for responsible water use. A common thread found in these papers is the understanding driving criteria for current water practices, and measurement of these criteria will enable continual improvement. An example of this is the assessment of the water footprint for production activity in the Peruvian Amazon by Repsol in their journey toward their Blue certification. The assessment of the water footprint provided a benchmark for improvement, which, in turn, highlighted parameters to measure and key areas for mitigation.

This paper describes part of a program undertaken by South Sydney City Council to promote sustainable water management The aim of the project, named SQIRTS (Stormwater Quality Improvement & Reuse Treatment Scheme) was to demonstrate best-practice water management approaches, to learn from the process of implementing these, and to encourage the further use of these technologies. It comprises three main components located in a suburban park: a gross pollutant trap (GPT), a stormwater reuse system, and interpretative artworks that aim to educate and interpret the water processes within the park. Results from the pre-construction monitoring program are presented.
