Assessment of wastewater treatment plant design for small communities: Environmental and economic aspects
چکیده انگلیسی

The preliminary design and economic assessment of small wastewater treatment plants (less than 2000 population equivalent) are issues of particular interest since wastewaters from most of these agglomerations are not covered yet. This work aims to assess nine different technologies set-up for the secondary treatment in such type of facilities embracing both economic and environmental parameters. The main novelty of this work is the combination of an innovative environmental decision support system (EDSS) with a pioneer approach based on the inclusion of the environmental benefits derived from wastewater treatment. The integration of methodologies based on cost–benefit analysis tools with the vast amount of knowledge from treatment technologies contained in the EDSS was applied in nine scenarios comprising different wastewater characteristics and reuse options. Hence, a useful economic feasibility indicator is obtained for each technology including internal and external costs and, for the first time, benefits associated with the environmental damage avoided. This new methodology proved to be crucial for supporting the decision process, contributing to improve the sustainability of new treatment facilities and allows the selection of the most feasible technologies of a wide set of possibilities.


► Environmental decision support system embracing environmental and economic aspects
► Ranking wastewater treatment technologies for small communities according to sustainability criteria
► Environmental benefit analysis of several wastewater treatment technologies under different scenarios
► Membrane bioreactor technology is the only one with the potential to produce an effluent suitable for all analyzed scenarios.
