  • Stakeholder involvement in water management: the role of the stakeholder analysis within participatory processes

    Water is a central resource supporting human activities and ecosystems and it is required for different purposes and uses that are often conflicting. Existing water-related problems are expected to increase and conventional water resource management systems are not likely to be able to face future challenges. There is the need for an integrated water resources management, which should be ...

  • Controlling Parameters in Water Analysis

    The COD (Chemical Oxygen Demand) is one of most important parameters in water analysis. In Germany as in nearly all European countries tax for indirect discharges is based on the COD. Using the oxygen consumption is reasonable in the case of tax because the delay time of waste water in a treatment plant depends mainly on its biological activity. The oxygen consumption again is a degree of ...

  • The role of process water in pathogen reduction

    The USDA’s Pathogen Reduction/Hazard Analysis and Critical Control Point (HACCP) rule in July of 1996 required all meat and poultry slaughter plants to adopt a system of process controls to prevent food safety hazards. It contained four components: standard operating procedures (SOPs) for sanitation, HACCP plans, generic E. coli testing and Salmonella performance standards. With the ...

  • The urban water reform project: a critical discourse analysis of the water policy making process in Delhi, India

    Making sense of policy processes in India requires an understanding of how particular ways of thinking about water have gained ascendancy in national and state discourses, and how they have determined the frame through which water is perceived, defined and handled. The way in which the concept of water is framed has important implications for the ways in which water reform policies come to be ...

  • Solvent-free oil-in-water analysis

    Non-ionic surfactants can homogenize oily, produced water samples, creating optically clear microemulsions that are ideal for fluorescence measurements [1]. The use of surfactants to reduce fouling and improve the performance of on-line, fluorescence-based, oil-in-water monitors has been reported previously [2,3]. This paper describes the use of surfactants to prepare discrete water samples ...

  • Water Quality Analysis Safeguarding Families

    Water is intensely purified and treated by water authorities before being ready for thousands of families. Everybody expects clean and safe tap water when turning on their taps. A water quality analysis center in Shanghi, China excels in its water testing and analysis with fully automatic potentiometric titration. Traditional Water Quality Analysis In order to ensure water hygiene and safety ...

  • Analysis of the impact of intermittent distribution by modelling the network-filling process

    In many countries, users acquire private tanks to reduce their vulnerability to water scarcity. In such conditions, water managers often apply intermittent distribution in order to reduce the water volumes supplied to the users. This practice modifies the hydraulic behaviour of the network and determines competition among users that need to collect enough water resource for their uses. ...

  • Catchment process affecting drinking water quality, including the significance of rainfall events, using factor analysis and event mean concentrations

    To ensure the protection of drinking water an understanding of the catchment processes which can affect water quality is important as it enables targeted catchment management actions to be implemented. In this study factor analysis (FA) and comparing event mean concentrations (EMCs) with baseline values were techniques used to asses the relationships between water quality parameters and linking ...

  • A critical process analysis of wine production to improve cost, quality and environmental performance

    ABSTRACTWine production in South Africa is delocalised, with numerous small-to-medium sized producers within several regions within the Western Cape. Whilst adapting to new technological changes, producers have to respond to pressure from consumers and governments regarding the environmental consequences of winemaking, especially water usage and pollution. To date, no systematic analysis ...

  • Sensitivity analysis on parameters and processes affecting vapor intrusion risk

    A one‐dimensional numerical model was developed and used to identify the key processes controlling vapor intrusion risks by means of a sensitivity analysis. The model simulates the fate of a dissolved volatile organic compound present below the ventilated crawl space of a house. In contrast to the vast majority of previous studies, this model accounts for vertical variation of soil water ...

  • Characterisation of water–oil drainage process through a reservoir rock sample by digital core analysis

    Oil–water relative permeability and capillary pressure of a water–wet digital core are computed using the finite–volume/volume of fluid method and mimicking traditional laboratory steady–state experiments carried out on a water saturated sample. Commercial software is used for immiscible multiphase fluid flow simulations, carried out on a low–cost multicore workstation, and the pore–scale data ...

  • The use of response surface methodology for modelling and analysis of water and wastewater treatment processes: a review

    In recent years, response surface methodology (RSM) has been used for modelling and optimising a variety of water and wastewater treatment processes. RSM is a collection of mathematical and statistical techniques for building models, evaluating the effects of several variables, and obtaining the values of process variables that produce desirable values of the response. This paper reviews the ...

  • Linking Uncertainty Analysis with Trading Ratio Determination from TMDL Allocation Process

    ABSTRACTTMDL allocation is central to the overall TMDL process because it creates a technically feasible and reasonably fair division of the allowable load among sources. An innovative approach for TMDL allocation and implementation is the watershed-based pollutant trading. Given the inherent scientific uncertainty for the tradeoffs between point and nonpoint sources, setting of trading ratios ...

  • Sensitivity analysis in a simulated auto thermal Natural Gas reforming process

    Auto Thermal natural gas Reforming (ATR) is one of the mostly used conventional hydrogen generation technologies by the highly developed countries. ATR reactors do not need any direct or indirect heat exchanger, and that is why they are more compact and so preferable than the other reformers. In this study, a process including reformers, carbon dioxide sequestration and a cryogenic separation ...

  • The Harvard Water Federalism Project – process and substance

    This Special Edition of Water Policy is one outcome of an innovative educational and research project, the Harvard Water Federalism Project, designed to train a new generation of students from a wide variety of disciplines to address the growing challenge of water security. This paper describes the core ideas behind the project, namely the creation of a new generation of ‘specialized ...

  • Degradation of azo dyes in water by Electro-Fenton process

    Abstract The degradation of the azo dyes azobenzene, p-methyl red and methyl orange in aqueous solution at room temperature has been studied by an advanced electrochemical oxidation process (AEOPs) under potential-controlled electrolysis conditions, using a Pt anode and a carbon felt cathode. The electrochemical production of Fenton's reagent (H 2O 2, Fe 2+) allows a controlled in situ generation ...

  • Drinking water quality monitoring using trend analysis

    One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled ...
