Controlling organic micropollutants in urban (waste) water treatment by activated carbon adsorption and membrane technology. Rosa, M. J. The number of climate-related disasters has progressively increased in the last two decades and this trend will drastically exacerbate in the medium- and long-term horizons according to climate change projections. In this framework, through a multi-disciplinary team and a strong background acquired in recent projects, ICARIA aims to promote the use of asset-level modeling to achieve a better understanding of climate related tangible direct and indirect impacts on critical assets due to complex, cascading, and compound disasters. Furthermore, it takes into account the related risk reduction provided by suitable, sustainable, and cost-effective adaptation solutions. ICARIA focuses on both (i) critical assets and services that were not designed for potential climate change-related impacts that can increase the unplanned outages and failures, and (ii) on housing, natural areas, and population. Cutting edge methods regarding climate scenario building, asset-level-coupled models, and multi-risk assessment approaches will be implemented and replicated in three EU regions to understand how future climate scenarios might affect critical assets and to provide decision-making support tools to private and public risk owners to assess the costs and benefits of various adaptation solutions.

Advanced management of urban water treatment systems Rosa, M. J. This document contains the programme of a curricular unit entitled “Advanced management of water treatment systems” prepared for submission to Habilitation (“Provas de Agregação”) in Environmental Engineering at Instituto Superior Técnico, Lisbon University, according to point b), article 5 of the Decree-law 239/2007, of 19th June. The programme’s format adopted follows the template currently required by the Portuguese Assessment and Accreditation Agency for University Study Programmes (A3ES), though providing more detail whenever considered relevant (i.e., exceeding max 1000 characters, particularly in Syllabus).

Energy and Carbon Balance in Wastewater Treatment Plants Duarte, B. This dissertation explores energy balances and GHG emissions in WWTP, focusing on estimating the latter and understanding the roles both variables play in advancing decarbonisation and energy neutrality efforts. The primary objectives are to evaluate the applicability of existing GHG quantification tools for WWTP, equipping utilities with the means to assess their own CF, identify GHG emission hotspots, and implement targeted reduction strategies. Additionally, this research establishes a national baseline for Portuguese wastewater services, analysing energy consumption and autonomy and GHG emissions using data from a representative sample of bulk and retail operators. To achieve these goals, two tools (ECAM and the Svenskt Vatten's tool) were applied to two case studies (Serzedelo II and Quinta da Bomba), with national baseline values also quantified using the selected tools' methodologies. Key findings suggest that, while these tools may not provide exact values, they are effective in estimating the relative contributions of different activities to the overall CF of a plant. The study highlights the need to deepen understanding of GHG emissions in Portuguese wastewater services and their connection to energy consumption and self-sufficiency. By offering insights into GHG estimation and energy management, this research provides a foundation for regulators and stakeholders to make informed decisions, supporting a more sustainable future for WWTP. Ultimately, it sets the stage for a standardised national approach to the assessment of the climate impact of these utilities, fostering accountability and proactive GHG management.

Avaliação e tratamento do risco na produção de água para reutilização Graça, A. A reutilização de água corresponde à utilização de água que provém de água residual e que alcança, após o tratamento necessário, a qualidade apropriada para o uso pretendido, tendo em conta os riscos para a saúde e para o ambiente e a legislação aplicável. A reutilização de água oferece uma origem alternativa de água que está constantemente disponível em zonas urbanas. A produção de Água para Reutilização (ApR) constitui, assim, um objetivo adicional no tratamento de águas residuais a integrar no funcionamento corrente das ETAR urbanas, sempre que existam condições para a utilização desta origem alternativa de água. Esta dissertação pretende contribuir para a aplicação de uma metodologia de avaliação e tratamento do risco associado à produção de água para reutilização em ETAR urbanas. Para atingir o objetivo proposto procedeu-se a: a) definição de objetivos e revisão do estado da arte das tecnologias de desinfeção de águas residuais; b) análise da metodologia a aplicar; c) definição de casos teóricos representativos de diferentes situações de produção de ApR; d) aplicação da metodologia nesses casos. O trabalho desenvolvido justifica-se pela necessidade de aplicar procedimentos claros na avaliação do risco na produção de água residual, tal como definido no Decreto-Lei n.º 119/2019, de 21 de agosto.
