Introduction
My main research interest are drinking water quality, wastewater treatment plants performance assessment and wastewater treatment technologies, with special emphasis on nature-based solutions to remove microorganisms, natural organic matter and contaminants of emerging concern.
The urban waste management, regarding methodologies for waste reduce, reuse and recycle, are also areas were contribute in teaching, as well as waste valorization.

The main goal of a wastewater treatment plant (WWTP) is to comply with the treated wastewater (TWW) quality requirements. However, the assessment of this compliance is a rather complex process for WWTPs in the EU Member States, since it requires the integration of a large volume of data and several criteria according to EU Directives 91/271/EEC and...
Removal efficiencies are often used to assess the performance of a single or a group of unit operations/processes (UOPs) of a wastewater treatment plant (WWTP). However, depending on the influent concentration (Cin), the same efficiency of removal (Er) may be insufficient or excessive to achieve the UOP or WWTP effluent quality requirements, expres...
The Azores archipelago is located in the North Atlantic Ocean, including nine volcanic islands. The Azores climate, temperate oceanic, is influenced by the Azores anticyclone, being characterized by high air humidity indices, low thermal amplitude, abundant precipitation and persistent wind. Like other urban areas, Ponta Delgada, in S. Miguel Islan...
Constructed wetlands are considered integrated ecosystems and a promising wastewater
treatment option, relying on vegetation, soils, and microbial assemblages. The potential dispersal of effluents from domestic septic systems, the application of dairy farm effluents containing excessive nutrients and pathogens into pastures, and undertreated efflue...
Na Região Autónoma dos Açores o abastecimento público de água é realizado maioritariamente com recurso a origens subterrâneas, com desinfeção prévia à distribuição. De acordo com o 6.º objetivo para o desenvolvimento sustentável das Nações Unidas, a diminuição da poluição nas origens de água é uma das formas de melhorar a qualidade da água final. A...
The constructed wetlands (CWs) are natural engineered systems, suited in general for wastewater treatment from small agglomerations and individual houses. These systems are characterized by low energy and low chemical consumption, and the water treatment is due to biological, chemical and physical processes occurring in granular media, biofilms and...
El agua en la región de la Macaronesia es obtenida, dependiendo del archipiélago considerado, mediante el aprovechamiento de recursos subterráneos principalmente, seguido de los recursos no convencionales, como la desalación y depuración de aguas y, finalmente, en mucha menor cuantía, los recursos superficiales. Las dos últimas fuentes no presentan...

Performance assessment of water supply and wastewater services is today a major issue. Over the past six years, the National Civil Engineering Laboratory (Portugal) has been developing performance assessment systems for drinking water treatment plants (WTPs) and wastewater treatment plants (WWTPs). In 2009, a national field-test was launched in Por...
A performance assessment system (PAS) is an important instrument to provide a cost-effective and sustainable management of wastewater treatment plants (WWTPs). Despite the fact that many PASs have been developed in recent years, important aspects of WWTP evaluation have not yet been considered. This paper presents the framework and the overall perf...
RESUMO A Iniciativa Nacional de Avaliação de Desempenho de ETA e ETAR Urbanas «PASt21» é um projecto de I&DT que envolve o LNEC, I.P., a UNA-PD, dez empresas e a Direcção de Engenharia da Águas de Portugal, S.G.P.S. S.A., a AGS, S.A., os SMAS de Almada e a ERSAR. Conta ainda com o apoio da APESB e da APRH e decorre de Maio de 2009 a Maio de 2011. O...
2); Helena ALEGRE (3); Catarina SILVA (4); Pedro RAMALHO (5) Resumo Os principais desafios actuais da gestão de estações de tratamento de águas residuais (ETAR) urbanas são o cumprimento dos requisitos de descarga, da água para reutilização e das lamas para valorização, a optimização da utilização de recursos e a diminuição da pegada ecológica. Par...
