UCT-MBR vs IFAS-UCT-MBR for Wastewater Treatment: A Comprehensive Comparison Including N2O Emission
2017
In this study the performance (in terms of carbon and nutrient removal) and N2O emission of two plant configurations adopting innovative technologies were investigated. With this regards, an University Cape Town (UCT) membrane bioreactor (MBR) plant and an Integrated Fixed Film Activated Sludge (IFAS) -UCT-MBR plant were monitored. Both plants treat real wastewater under two different values of the influent carbon nitrogen ratio (C/N = 5 mgCOD/mgN and C/N = 10 mgCOD/mgN). Results have shown the highest carbon and nutrients removal efficiencies for the IFAS-UCT-MBR configuration during both the two investigated C/N values. Furthermore, the lowest N2O emission occurred for the IFAS-UCT-MBR.
Evaluation of biomass activity and wastewater characterization in a UCT-MBR pilot plant by means of respirometric techniques
2011
Abstract Over the last two decades, Membrane Bioreactors (MBRs) emerged even more for wastewater treatment, ensuring high removal efficiencies as well as very small footprint requirements. Indeed, in this kind of process, a modification in biomass activity and viability can exist compared to that of a CAS process. In this context, respirometric analysis represents a reliable tool in order to evaluate the actual biomass kinetic parameters, to insert in mathematical models in the design phase, as well as to monitor the biomass viability, especially when these processes are operated with high SRT values. The paper presents some results of respirometric techniques applied for the characterisati…
Implementación de estrategias y herramientas de coordinación sociosanitaria en un departamento de salud
2018
Resumen: Es objetivo de este artículo mostrar una experiencia de práctica novedosa implementada por la dirección de un departamento de salud. Se expone un modelo organizativo de coordinación sociosanitaria entre los diferentes niveles asistenciales y sectores, estableciendo sinergias de los recursos sociales y sanitarios comunes del Departamento de Salud Clínico-Malvarrosa (Valencia). Tras un año, se han constituido cinco consejos de salud de zona básica en atención primaria y una comisión de coordinación sociosanitaria integrada por tres subcomisiones: 1) de atención asistencial social y sanitaria, 2) de asociacionismo y voluntariado hospitalario, y 3) de acción comunitaria y participación…
Performance of a hybrid activated sludge/biofilm process for wastewater treatment in a cold climate region: Influence of operating conditions
2013
a b s t r a c t The main aim of the study was to investigate a hybrid MBBR process, mostly in terms of organic matter removal and nitrification, when operating with different values of the mixed liquor sludge retention time (SRT), and highlighting the influence of temperature on the process. Based on experience in practice it was hypothesized that nitrification could be maintained at far lower SRT's than in conventional activated sludge systems and with high organic loading rates applied. A field gathering campaign has been carried out on a hybrid activated sludge/biofilm. The obtained results highlighted that the pilot plant was capable to remove the organic matter at loading rates up to 3…
Wastewater modification processes in a stabilization reservoir: a new mathematical model
2018
The paper presents a mathematical model for the simulation of the ecology of a wastewater stabilization reservoir (WSR). WSRs are hypertrophic aquatic systems devoted to water storage in warm countries where shortage conditions are often encountered. Several factors that affect the stabilization reservoir’s effluent quality were taken into account: hydraulics and hydrology, solar radiation, reaeration, algae, zooplankton, organic matter, pathogens, and sediment-water interactions. The model quantifies the specific influence of each factor on effluent quality, and evaluating the correlation between the different factors. State variables included in the model were: algae, dissolved oxygen, or…

BIOLOGICAL DENITRIFICATION OF GROUNDWATER: BIO-PRB COLUMN TEST PERFORMANCES EVALUATION
2012
The occurrence of nitrates in groundwater is steadily raising concern due to possible health consequences of nitrate ingestion. Biological denitrification in BIO-PRB is the enhancement of a natural process that occurs naturally when bacteria live in an environment void of oxygen with carbon availability. Bio-PRB represent a perspective of development for PRB technique but, despite the fact that this technology has already been widely used for chlorinated solvents, data on denitrification PRBs are still scarce. This paper reports on the results of an experimental study carried out for 214 days on a bench-scale pilot column (10 cm in internal diameter and 100 cm in length with sampling ports …
Análisis de los determinantes socioeconómicos y de la morbilidad del Departamento de Salud Valencia Clínico-Malvarrosa. Desarrollo de un índice de pr…
2021
Los CRG (Clinical Risk Group) permiten estratificar a la población según la morbilidad, pero hasta ahora, no se ha estudiado el impacto de variables socioeconómicas sobre ésta utilizando este agrupador. Se dispone de información socioeconómica de cada individuo en la base de datos APSIG. Los índices de privación son indicadores compuestos que se utilizan para medir desigualdades en salud entre los territorios. El Departamento de Salud Valencia Clínico-Malvarrosa (DSVCM) ofrece cobertura a Zonas Básicas de Salud (ZBS) de la ciudad de Valencia y pueblos de L´Horta Nord. Esta diversidad geográfica y social aporta singularidad y riqueza al estudio de las desigualdades en salud. OBJETIVO. Analiz…
Le ordinanze in materia di protezione civile, tra potere di urgenza e urgenza di potere
2020
Il presente contributo ripercorre le tappe che hanno condotto all’affermazione del potere di ordinanza di protezione civile. Si tratta di un percorso caratterizzato dalla tensione con principi propri di un moderno Stato di diritto, come quelli di legalità e tipicità dell’azione amministrativa. Tale potere è ricollegato al manifestarsi di eventi emergenziali eccezionali, e si caratterizza, infatti, per una duplice deroga all’ordinamento giuridico. Da un lato vengono dispensati i normali presupposti d’esercizio di ogni singolo potere d’autorità. Sotto altro profilo, anche il contenuto ha carattere derogatorio, potendo consistere nell’adozione di qualsiasi potere amministrativo, tra quelli pre…
Illicit drugs consumption evaluation by wastewater-based epidemiology in the urban area of Palermo city (Italy)
2017
Introduction. A wastewater-based epidemiology approach was performed to estimate the drug consumption in Palermo city, the fifth largest city of Italy with a population of 671 696 inhabitants, and to investigate the monthly variability of drug loads in wastewater from different areas of the city. A seven-months detection campaign was conducted at the two wastewater treatment plants of the city. Methods. Following a pre-treatment, 32 samples of wastewater were analyzed by liquid chromatography-tandem mass spectrometry. Results. We estimated a mean cocaine use in Palermo of 0.19 g/day/1000 people, corresponding to 1.90 doses/1000 people and cannabinoids use of 2.85 g/day/1000 people, correspo…
