This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.

"Once one of the most important port cities in the New World, Havana was a model for the planning and construction of other colonial cities. This book tells the story of how Havana was conceived, built, and managed and explores the relationship between colonial empire and urbanization in the Americas. Guadalupe García shows how the policing of urban life and public space by imperial authorities from the sixteenth century onward was explicitly centered on politics of racial exclusion and social control. She illustrates the importance of colonial ideologies in the production of urban space and the centrality of race and racial exclusion as an organizing ideology of urban life in Havana. Beyond the Walled City connects colonial urban practices to contemporary debates on urbanization, the policing of public spaces, and the urban dislocation of black and ethnic populations across the region"--Provided by publisher.
