A Process Modelling-Life Cycle Assessment-MultiObjective Optimization tool for the eco-design of conventional treatment processes of potable water

摘要

The eco-design of conventional potable water production processes is impeded by the high variability of operating conditions as a function of the inlet and the quality of outlet water, and by the large diversity of feasible technical solutions and treatment processes. Based on an already developed library of unit process modules which generates water treatment process inventories with integrated Life Cycle Assessment (EVALEAU tool), this work presents a new tool to combine Process Modelling, Life Cycle Assessment and MultiObjective Optimization (PM-LCA-MOO tool) for conventional potable water production processes, in order to solve the challenges of interconnecting LCA results and other conflicting process objectives.
