Rainwater reuse in urban areas: a mathematical model and a longterm modelling approach
2018
Natural water resources are becoming increasingly limited due to global-scale climate change and water availability issues have become so severe that they must be addressed. Given these issues, reuse of wastewater and rainwater provides a promising way to cope with water shortages. This paper describes an investigation into the efficiency of rainwater usage systems. A conceptual model was built to assess the behaviour of rainwater tanks and their effectiveness in coping with water shortages. The study is based on a long-term simulation (12 years) of different rainwater reuse tank schemes. The associated reductions in residential freshwater demand (water reuse efficiency) and wetweather runo…
Occurrence of Microplastics in Waste Sludge of Wastewater Treatment Plants: Comparison between Membrane Bioreactor (MBR) and Conventional Activated S…
2022
In this study, the presence of microplastics in the sludge of three wastewater treatment plants (WWTPs) was examined. The investigated WWTPs operated based on a conventional activated sludge (CAS) process, with (W1) or without (W2) primary clarification, and a membrane bioreactor process (MBR) (W3). The microplastics (MPs) concentration in the samples of W3 was approximately 81.1 ± 4.2 × 103 particles/kg dry sludge, whereas MPs concentrations in W1 and W2 were 46.0 ± 14.8 × 103 particles/kg dry sludge and 36.0 ± 5.2 × 103 particles/kg dry sludge, respectively. Moreover, MPs mainly consisted of fragments (66–68%) in the CAS plants, whereas the fra…
Modelling biological nitrogen and phosphorus removal with soluble microbial products (SMP) production-degradation processes
2011
Over the last two decades, Membrane Bioreactors (MBR) are increasingly used for wastewater treatment. Mathematical modelling of MBR systems has played a key role in order to better explain the effect of their peculiarities. Indeed, several MBR models have been presented in literature in order to improve the knowledge on MBR systems: biological models, hybrid models which include soluble microbial product (SMP) modelling, physical models able to describe the membrane fouling and integrated models which couple the hybrid models with the physical ones. However, among the existing MBR models only few integrated models have been developed which take into account the existing relationship between…
I SISTEMI DI GESTIONE PER LA QUALITÀ E I MODELLI DI ACCREDITAMENTO VOLONTARIO E DI ECCELLENZA NELLE AZIENDE SANITARIE SICILIANE
2015
Introduzione: Il programma di ricerca è finalizzato allo studio del grado di sviluppo organizzativo dei “modelli sistemici” per la qualità dell’assistenza nelle strutture sanitarie pubbliche e private siciliane, prendendo spunto dalla rilevazione condotta dalla Direzione Generale della Programmazione sanitaria, dei livelli di assistenza e dei principi etici di sistema del Ministero della Salute nel 2007 a livello nazionale. Materiali e Metodi: Il questionario è stato progettato per la compilazione on line, prevedendo domande miranti a rilevare il livello di diffusione degli strumenti e dei metodi per il miglioramento della qualità dell’assistenza, in riferimento all’anno 2013, ed è stato in…
Towards a reduction of greenhouse gas emission from wastewater treatment plants: a new plant wide experimental and modelling approach
2016
The increasing interest in greenhouse gas (GHG) emissions from wastewater treatment plants (WWTPs) has led to the development of new tools for their design and management. Studies about gas emissions show that the sewer collection and the wastewater treatment plant are anthropogenic GHG potential sources, so they contribute to the climate change and air pollution. A wastewater treatment plant receives wastewater from sewers and, while produces treated water for discharge into surface water, emits the three major greenhouse gases, CO2, CH4, and N2O, during the treatment processes, and additional amounts of CO2 and CH4 from the energy demands (Bani Shahabadi et al., 2009). Indeed, energy cons…
Global sensitivity analysis in environmental water quality modelling: Where do we stand?
2014
Global sensitivity analysis (GSA) is a valuable tool to support the use of mathematical models for environmental systems. During the last years the water quality modelling field has embraced the use of GSA. Environmental water quality modellers have tried to transfer the knowledge and experience acquired in other disciplines. The main objective of this paper is to provide an informed problem statement of the issues surrounding GSA applications in the environmental water quality modelling field. Specifically, this paper aims at identifying, for each GSA method, the potential use, the critical issues to be solved and the limits identified in a comprehensive literature review. The paper shows …
Optimización de la medida de la calidad de vida en personas mayores con dependencia en centros residenciales de Guipúzcoa: Escalas Fumat y Qualid
2019
La investigación tuvo como objetivo poner a disposición de los centros residenciales un conjunto de herramientas validadas para la medida de la calidad de vida de personas mayores con dependencia, tanto con como sin deterioro cognitivo grave, que fueran ágiles y sirvieran para orientar el diseño de intervenciones y guiar la implantación de modelos de atención centrados en la calidad de vida de las personas. La escala FUMAT ADAPTADA se construyó con 24 ítems rescatados de la escala FUMAT (Verdugo, Gómez y Arias, 2009) de entre los que los 22 profesionales de 4 grupos focales validaron para su uso en centros residenciales. Se validó confirmatoriamente (n=191), al igual que la escala QUALID (W…
Fonti per la storia del Manicomio di Palermo alla Vignicella (1884-1902)
2020
Il testo ripercorre le tappe che hanno condotto alla realizzazione di una delle più vaste opere pubbliche di stampo sanitario realizzate a Palermo nel XIX secolo: l'Ospedale Psichiatrico alla Vignicella. Tramite l’individuazione e l’analisi delle principali fonti ottocentesche e dei primissimi del Novecento, pur confrontandosi con la più recente letteratura periegetica, si fissano alcuni punti fermi rispetto alla progettazione ed esecuzione dei lavori, oltre che, non di meno, in relazione alla concezione scientifica sulle quali erano state fondate. Le immagini d’epoca accompagnano il testo in senso illustrativo e documentario. The text traces the steps that led to the construction of one of…
