Sustainable design of different seawater reverse osmosis desalination pretreatment processes
Sustainable development is usually presented using the three pillar model: economy, environment and society. This research uses life cycle based assessments in conjunction with process system engineering methods for the design and analysis of sustainable processes with the example of pretreatment of seawater membrane desalination. At the first step, the sustainability potential of several state of the art process alternatives is analysed (namely granular media- and membrane-based filtration). Conducting a broad environmental LCA (life cycle assessment, using GaBi4 software) together with a LCC (life cycle costs assessment, according to SETAC (Society of Environmental Toxicology and Chemistry) guidelines) forms the so called ecoefficiency analysis (based on a definition by Germany's Institute for Applied Ecology) which together with a qualitative process performance assessment gives a good idea about the sustainability potential of the different process alternatives. The results show that the current trend of using a membrane based pretreatment is proven here to not always be a more sustainable process solution.
