Strategies for Improving Optimal Positioning of Quality Sensors in Urban Drainage Systems for Non-Conservative Contaminants
2021
In the urban drainage sector, the problem of polluting discharges in sewers may act on the proper functioning of the sewer system, on the wastewater treatment plant reliability and on the receiving water body preservation. Therefore, the implementation of a chemical monitoring network is necessary to promptly detect and contain the event of contamination. Sensor location is usually an optimization exercise that is based on probabilistic or black-box methods and their efficiency is usually dependent on the initial assumption made on possible eligibility of nodes to become a monitoring point. It is a common practice to establish an initial non-informative assumption by considering all network…

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…
Geschlecht und Gender in der Medizin
2005
Gender specific medicine is a part of gender-research, which has been insufficiently considered up to the present in medicine, sanitation and politics. Part of the scientific medicine simply ignores the knowledge that menand women are different in feeling, thinking and social acting without any question. Doctors often incline to treat all their patients as if there was just one gender: i. e. the male one. It is without dispute that men and women vastly suffer from the same diseases, but they often go through them quite differently. The female body seems to work differently from the male one in nearly all respects - starting with the brain, going on with the heart, cardiovascular, lungs, sto…
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…
L’attività normativa del governo nel periodo 2020-2021
2022
L’articolo descrive l’attività normativa del governo nel periodo 2020-2021. Il biennio è stato segnato dalle misure di contrasto alla pandemia da Covid-19. Di conseguenza, si prendono in considerazione, innanzitutto, le misure sanitarie adottate nel periodo emergenziale e concernenti tanto gli obblighi di distanziamento fisico e di contenimento dell’epidemia, quanto le disposizioni relative alle vaccinazioni e alla presentazione del «certificato verde» o green pass. Successivamente, si dà conto delle principali normative adottate a supporto dell’economia e del sistema imprenditoriale, distinguendo tra gli ausili finanziari destinati a ridurre l’impatto negativo della pandemia sulle aziende …
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 …
