Design of sustainable municipal wastewater treatment plants

摘要

Nowadays, an adequate design for wastewater treatment plants (WWTP) based on optimization methods is fundamental with sustainability factors under consideration. This can be achieved by developing a systematic methodology based on models that uses as decision criteria sustainability metrics, such as costs, contaminant removal and customer value. As a preliminary analysis, two dimensions of sustainability (economic and environmental) have been studied as mono-objective functions to make evident the need for a comprehensive assessment when designing a WWTP. This was carried out considering a case study for the treatment municipal wastewater from Mexico City.
