Significance and Current Status of Wastewater Reuse in Sicily
1991
In Sicily wastewater is being regarded as a supplemental source of water, especially for agricultural use, which represents the greatest demand at present and in the future. That is because water demand is already approaching total usable resources, and severe shortage is experienced almost everywhere and in every sector. To help overcome possible implementation problems due to high salinity and pollutant concentrations, lack in monitoring capabilities, and emotional public perception of possible health risks, major field research programs have been undertaken, including an experimental station with a pilot plant and a series of field plots.
Wastewater Treatments for the Food Industry: Biological Systems
2017
This chapter provides a general overview of biological wastewater remediation systems in the food industry. Water reuse systems are becoming more and more interesting and promising technologies, depending on merely quantitative estimations, physical and chemical features of pollutants and the variability of these characteristics, week after week. Different systems are available for the food industry. Several of these remediation systems may be subdivided into four categories depending on the peculiar removal operation, including biological systems. Biological techniques aim to reduce organic loads and the remaining suspended materials in wastewaters from primary processes (after a prelimina…
Wastewater Treatments for the Food Industry: Physical-Chemical Systems
2017
This chapter provides a general overview of physical–chemical wastewater remediation systems in the food industry. Water reuse systems are becoming more and more interesting and promising technologies, depending on merely quantitative estimations, physical and chemical features of pollutants and the variability of these characteristics, week after week. Different systems are available for the food industry, depending on the final destination or water effluents and peculiar chemical–physical and biological features of the fluids before treatment. Several of these remediation systems can be subdivided into different groups, depending on the desired amount of gross removed matters, or into fou…
Rainwater Reuse in Urban Areas: A Mathematical Model and a Long-Term 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 wet-weather run…
From limit to centrality. Regeneration of the Genoa's port area through architectural and urban design
2012
This survey’s core is the case study of the regeneration of the port area and of the urban waterfront of the city of Genoa, as an emblematic example where the architectural and urban design plays an important role, oriented to the transformation of the port area and to the modification of the relationship that exists between the harbour and the city. In particular this will deepen the possibility, to reverse the condition of limit that characterizes the port area into a new centrality, through the design, passing by intermediate steps that redefine the modalities of access and of connection between city and port, breaking the condition of isolation that ports usually present. As a matter of…
Resilient cities and sustainable urban mobility in Sicily
2018
The global crisis that in recent years has been investing our planet at different levels - social, economic, political, cultural, environmental - has determined a constant change in the quality of life in the cities. Cities, unfortunately, increasingly vulnerable characterized by insecurity, uncertainty, unpredictability due to mistakes made in the past. This is why, today, urban planning is called to satisfy the new needs of the community through a planning that must be adapted to change. In this scenario, urban centers - in order to ensure high levels of quality of life and responsible management of territorial resources - they must re-examine their governance, their strategies for expans…
MAPS Project
2019
From 2016 to 2018 OC OPEN CITY Research Group of Politecnico di Milano / Dastu Department was involved within the European Program MAPS (acronymous for Military Assets Public Space), part of URBACT, financially supported by the European Union. The program was leaded by the Municipality of Piacenza, as city leader of a group of 10 European cities which shared the architectural and urban topic of neglected military assets’ regeneration. Together with associations and citizens, Politecnico di Milano research group worked on ideas and visions for reuse of Laboratorio Pontieri area (one of the case-study of OC2018) with an open and participatory approac as player of ULG (Urban Local Group). For …
Research and Projects for the Recovery of the “Tifeo” Power Station in Augusta, Sicily
2016
The buildings of the Tifeo Augusta Power Station (SR) significantly tell us, even today, the history of the Sicilian industrial dream at the end of the Fifties. However, with the passing of time, it revealed the underlying contradictions still present today in Augusta together with polluting and oppressive petrochemical plants built during those times. Regardless of any recovery theory about the Augusta Power Station, it is clear that an open and multidisciplinary look cannot be ignored, locating the power station in the actual and future setting of the vastest territory in which it is sited. The past, the present and, of course, the future of the Augusta area are tightly connected to the s…
Architettura storica: conoscenza obiettiva e rifunzionalizzazione
2010
Il progetto di restauro è basato sulla conoscenza obiettiva dell'architettura e il contributo mostra il percorso metodologico per accrescere la quantità di informazioni che supportano l'elaborazione del progetto. L'obiettivo dell'intervento, nel rispetto del carattere storico dell'edificio, è la definizione di una utilizzazione compatibile. The restoration project is based on objective knowledge of architecture and the contribution shows the methodological approach to increase the amount of information that support the development of the project. The goal of the intervention, in accordance with the historic character of the building, is the definition of a compatible use.
Ethics of restoration and conservation science: the completion and reuse of the former Mother Church in Santa Margherita di Belice (Sicily) / Ética d…
2016
Restaurare l’architettura significa conservare la sua essenza autentica e le stratificazioni storiche, rispettare il criterio della distinguibilità e attualizzare le funzioni che racchiude. Questo moderno indirizzo culturale e metodologico ha sostanziato il progetto di restauro e di rifunzionalizzazione della ex chiesa madre di Santa Margherita di Belice, in Sicilia, che oggi ospita il “Museo della Memoria”. L’istinto progettuale conservativo si è manifestato fin dalle prime ipotesi d’intervento, quando è stata rigettata la possibilità di riproporre “nuovamente” le masse murarie del monumento, sconquassate da un violento terremoto nel 1968. Si è scelto, infatti, d’attuare un’operazione raff…
