A model for wastewater organic removal and fouling development in a SMBR pilot plant
2007
The paper presents the setting up of a mathematical model for membrane bioreactor able to simulate physical-biological wastewater organic removal. The model is basically divided into two sub-models: the first sub-model is basically devoted for the simulation of the biological features and the second one for the physical processes. In particular regarding the biological aspects, the ASM concept has been employed. On the other hand, the physical processes have been modelled considering the deep-bed theory taking into account not only the effect of the physical membrane filtration but also the cake layer effect. This latter operates as a biological membrane leading to a further reduction of th…
Economic and Life Cycle Analysis of Passive and Active Monitoring of Ozone for Forest Protection
2021
At forest sites, phytotoxic tropospheric ozone (O3) can be monitored with continuously operating, active monitors (AM) or passive, cumulative samplers (PM). For the first time, we present evidence that the sustainability of active monitoring is better than that of passive sensors, as the environmental, economic, and social costs are usually lower in the former than in the latter. By using data collected in the field, environmental, social, and economic costs were analyzed. The study considered monitoring sites at three distances from a control station in Italy (30, 400, and 750 km), two forest types (deciduous and Mediterranean evergreen), and three time windows (5, 10, and 20 years of moni…

EFFICACIA DI UN INTERVENTO FORMATIVO RIVOLTO AGLI OPERATORI SANITARI DELL'AZIENDA OSPEDALIERA UNIVERSITARIA (AOU) POLICLINICO "P. GIACCONE" DI PALERM…

INTRODUZIONE: La vaccinazione antin uenzale rappresenta la misura preventiva più ef cace nel limitare la diffusione del virus in uenzale ed il Ministero della Salute raccomanda fortemente tale misura precauzionale a tutti gli operatori sanitari (OS). Gli OS sono ripetutamente esposti al virus, rappresentando una delle principali fonti di contagio per i pazienti e anticipando la malattia in uenzale rispetto alla popolazione generale. In numerosi studi, gli OS hanno riportato che la strategia preferita per implementare le coperture antin uenzali tra gli stessi, era l’organizzazione di corsi di formazione multidisciplinare sulla tematica. In questa ottica è stato svolto un intervento formativo…

INCIDENZA SULL’ANALISI DI RISCHIO DELLE MODALITÁ DI MISURA DEI SOIL GAS: IL CASO DI UN S.I.N. SICILIANO
2020
Il monitoraggio delle matrici aeriformi sta assumendo importanza crescente nell’ambito dei procedimenti di bonifica di siti contaminati, con riferimento sia all’esecuzione delle analisi di rischio, sia alla conseguente progettazione degli interventi di risanamento. L’utilizzo di misure dirette di campo si rivela di notevole interesse per la verifica di quelle indirette, ottenute con gli algoritmi implementati nei modelli matematici utilizzati per l’analisi di rischio. Obiettivo del lavoro presentato nella nota è stato quello di valutare l’influenza di misure dirette di soil gas e di flussi emissivi sull’analisi di rischio sanitaria. Come caso studio, si è considerato un S.I.N. nel territori…
WASTE PLASTICS MANAGEMENT IN MUNICIPALITIES: LOGISTICS AND PROCESSES IN LOMBARDIA (NORTHERN ITALY)
2013
A partnership of 49 Municipalities lying in Lombardia (Northern Italy) and belonging to the District “Monza and Brianza” has entrusted the management of the Municipal Solid Waste (MSW) to two Public Companies: “C.E.M. Ambiente S.p.A.” - which owns and operates a transfer station and a multi-material centre - and “SERUSO S.p.A.”, whose single facility is set up and equipped for a high performance factory sorting of the dry fraction of the urban waste. The catchment area is populated by 448 000, living in an area of 366 km2. The management system starts with household sorting for multi-bin curbside collection; followed by hauling to selection and physical treatment facilities; and last, trans…
Particle balance and return loops for microplastics in a tertiary-level wastewater treatment plant.
2021
Highlights: Dewatering by centrifugation was a step that removed a high number of MPs from the sludge. Sludge retained especially the fibrous microplactics. Reject water transported microplastics inside a wastewater treatment plant. Disc filter-based tertiary treatment ensured removal of 99% of microplastics in wastewater. Microplastics (MPs) from households, stormwater, and various industries are transported to wastewater treatment plants (WWTPs), where a high proportion of them are captured before discharging their residuals to watersheds. Although recent studies have indicated that the removed MPs are mainly retained in wastewater sludge, sludge treatment processes have gained less atten…
Towards a new protocol for field measurements of greenhouse gases from wastewater treatment plant
2016
Emissions into the atmosphere of greenhouse gases (GHGs), i.e., carbon dioxide, methane and nitrous oxide from wastewater treatment plants are of increasing concern in the water industry. In order to produce useful and comparable information for monitoring, assessing and reporting GHG emissions from wastewater treatment plants, there is a crescent need for a general accepted methodology. This paper aims at proposing the first protocol for monitoring and accounting GHG emissions from wastewater treatment plants taking into account both direct and internal indirect emissions focusing on sections known to be major responsible of GHG emissions i.e. oxidation tanks and sludge digestion. The main…
