“…New technologies are also considered to be of fundamental importance for the sustainable use of phosphorus in industrial processes, as is the case, for example, in the process for recovering phosphorus from oyster shell residues by means of pyrolisis, and in the use of physicochemical or incineration processes for recovering phosphorus from sanitary sewage sludge, making it available for reuse (Jegatheesan et al, 2009;Mihelcic et al, 2011).…”

Strategies for managing phosphorus in the environment have been considered to be of great significance. In light of debates about protecting water resources, tools for recovering and recycling phosphorus are being assessed, with the aim of guaranteeing the sustainability of natural reserves. This study discusses phosphorus dynamics in the environment and measures geared towards the management of its presence in water. In order to illustrate the situation in Brazil, we present an assessment of the size of the potential phosphorus load that is discharged daily into the Tietê River, State of São Paulo, by the urban population living in its basin. Due to its replacement in powdered detergents, the results showed a potential reduction in the amount of phosphorus discharged into the Tietê of about 11.7 t day -1 . The size of the potential phosphorus load that might be recovered from sewage sludge shows a scenario of great potential for re-using and recycling in agricultural areas, as long as the necessary care is taken regarding safety and environmental protection. Management methodologies, such as Cleaner Production (CP) techniques, are important tools for controlling water pollution, as they contribute to the reduction of phosphorus emissions. They can therefore improve the perception producers and consumers have of this issue, introducing reducing, recycling and recovering concepts, and assisting in compliance with public policies geared towards preserving the environment.Keywords: effluent, nutrients, water quality.A gestão do fósforo nas águas: estudo de caso do Rio Tietê, Brasil RESUMO O desenvolvimento de estratégias para gestão do fósforo nas águas tem sido considerado, cada vez mais, de grande importância para a manutenção da qualidade de vida. Assim, paralelamente às discussões sobre alternativas para promover a proteção das águas, são avaliadas ferramentas para controle das fontes e reciclagem do fósforo no meio ambiente, buscando garantir a sustentabilidade das reservas conhecidas e exploráveis. Face ao exposto, o objetivo deste trabalho é discutir a dinâmica do fósforo no meio ambiente e as medidas voltadas para a gestão de sua presença nas águas. A título de ilustração da situação vivenciada no Brasil a respeito desse assunto, apresenta-se um dimensionamento da carga potencial de fósforo lançada diariamente nas águas do rio Tietê, localizado no Estado de São Paulo, a partir da população urbana da bacia hidrográfica.

“…Changes have occurred in consumption and production patterns, with the endless increasing need for goods for millions of people (France, 2013;Jegatheesan et al, 2009;Makki et al, 2011). There have been many changes in lifestyle, as an example, longer and more frequent baths and showers, increasing use of washing machines and dishwashers, (Lake and Bond, 2007;Schleich, 2009).…”

“…This data provides benefits for water utility managers and researchers for planning and operating a water distribution network improving the overview of water demand and trends, determining the location and scale of water stress, determine the uncertainties of consumption and identifying leaks with the overall intention of satisfying consumer demand by maintaining reasonable pipe pressure (Jegatheesan et al, 2009;Lake and Bond, 2007;Portnov and Meir, 2008;Velázquez, 2006;Widén et al, 2009;Wong and Mui, 2007;Yurdusev and Firat, 2009). …”

In this paper, a periodic hourlybased model with meaningful parameters has been developed to analyze and forecast water demand as a function of time, thus enabling a better understanding of the consumption pattern and the condition of the pipe network. The model was tested by investigating the daily water consumption from selected categories of users which were isolated from different distribution networks in Sligo, Ireland. The flow data used was obtained in 15-min intervals and averaged in different time periods for analysis. In all cases, the model fittings obtained were highly consistent and all the parameters showed satisfactory confidence intervals (=0.05), thus demonstrating the reliability of this approach. The model provides a quick analysis revealing the regularities of water demand that could benefit water utility managers and researchers: to obtain optimal regulation and pumping schemes; for planning and design purposes; to control unexpected scenarios that can take place during the distribution of water; the performance of water distribution systems; and to locate possible network failures. In addition, the model parameters can be used as standard criteria for water utilities to compare precisely the water demand between different areas, identify complex trends and analyze the pipe network for managing, auditing and monitoring purposes.

This paper aims to evaluate the sustainability performance of machining operation of through-hardening steel, AISI 52100, taking into account the impact of the material removal process in its various aspects. Experiments were performed for dry and cryogenic cutting conditions using chamfered cubic boron nitride (CBN) tool inserts at varying cutting conditions (cutting speed and feed rate). Cutting forces, mechanical power, tool wear, white layer thickness, surface roughness and residual stresses were investigated in order to evaluate the effects of extreme in-process cooling on the machined surface. The results indicate that cryogenic cooling has the potential to be used for surface integrity enhancement for improved product life and more sustainable functional performance.
