Cost-effectiveness analysis for sustainable wastewater engineering and water re...
Costa, Sérgio; Coutinho, L.; Brito, A. G.; Nogueira, R.; Machado, A. Patrícia; Salas, J. J.; Póvoa, C.A cost-effectiveness integrated methodology applied in a water resources management and sanitation project in Minho and Lima’s region (Portugal) is presented. First, environmental objectives and programmes of measures (PM) are established and priorities are identified using a cause–effect assessment matrix and a global effectiveness index. Aiming to achieve more demanding goals, some complementary actions are c...
Depuranat project : sustainable management of wastewater in rural areas
Vera, L.; Martel, G.; Salas, J. J.; Sardón, N.; Nogueira, R.; Brito, A. G.; Faby, J. A.; Ramón, A.The Urban Wastewater Directive is aiming to implement adequate treatments of collected wastewater before 31 December 2005 in small communities with a population until 2000 equivalentinhabitant. Within the framework of the DEPURANAT project, co-financed by the European Interregional Cooperation Programme (Interreg IIIB Atlantic Arc), several Natural Reclamation Systems (NRS) based upon no-conventional technologi...
Economic and environmental assessment of small and decentralized wastewater tre...
Nogueira, R.; Brito, A. G.; Machado, A. Patrícia; Janknecht, P.; Salas, J. J.; Vera, L.; Martel, G.The aim of the present work was the assessment of economic and environmental aspects of decentralized energy-saving wastewater treatment systems. The formulated investment and operation cost functions were adjusted by a power law function. The different wastewater systems serving population settlements between 50 p.e. and 250 p.e., presented associated investment costs varying from €400/p.e. to €200/p.e. and an...
Life cycle assessment of wastewater treatment options for small and decentraliz...
Machado, A. Patrícia; Urbano, Lino; Brito, A. G.; Janknecht, P.; Salas, J. J.; Nogueira, R.Sustainability has strong implications on the practice of engineering. Life cycle assessment (LCA) is an appropriate methodology for assessing the sustainability of a wastewater treatment plant design. The present study used a LCA approach for comparing alternative wastewater treatment processes for small and decentralised rural communities. The assessment was focused on two energy-saving systems (constructed w...

The DEPURANAT project : sustainable management of wastewater in rural areas
Vera, L.; Martel, G.; Salas, J. J.; Sardón, N.; Nogueira, R.; Brito, A. G.; Faby, J. A.; Ramón, A.The DEPURANATt project received co-financing from the European Union through its interregional cooperation programme, Interreg IIIB Atlantic Arc Programme. This project, coordinated by the Canary Islands Institute of Technology, allowed French, Portuguese and Spanish institutions to work together on sustainable management of wastewater in rural and protected areas. Within the framework of this project, twelve n...
Cost-effectiveness analysis for sustainable wastewater engineering : a case stu...
Costa, Sérgio; Coutinho, L.; Nogueira, R.; Brito, A. G.; Salas, J. J.; Póvoa, C.The present work was focused on a methodological assessment for defining cost-effective measures regarding to wastewater sanitation in rural areas and was carried out within the project AQUA Project – Preliminary Studies for the Water Framework Directive Implementation at the Minho and Lima’s Rivers Basins. In order to assure a good ecological and chemical status in water bodies according to Water Framework Dir...
Bioindicators as a tool for monitoring and control biofilm reactors : a simplif...
Coutinho, L.; Salas, J. J.; Nogueira, R.; Brito, A. G.The control of wastewater treatment plants requires an extensive monitoring programme based on physicochemical costly routine analysis. Microbial populations are well known indicators of operational conditions in biological reactors. This research was carried out by the CENTA and the University of Minho in the scope of the Erasmus programme. The aim of the work was the development of a simplified approach, base...
Evaluación de los sistemas de depuración natural
Vera, L.; Martel, G.; Gutierrez, J.; Márquez, M.; Abreu Acosta, N.; Salas, J. J.; Sardón, N.; Herrera Melián, J. A.; Aguilar Bujalance, M. E.La fase de experimentación de los diferentes proyectos pilotos de depuración natural, su evaluación y seguimiento, ha constituido uno de los pilares fundamentales del Proyecto DEPURANAT. Los socios responsables de los proyectos piloto incluidos en dicha fase de Experimentación y Demostración establecieron, de forma común, un protocolo único de seguimiento, tanto analítico como de supervisión de la operación de ...
