  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • Using FTIR spectroscopy to measure hydrocarbon pollution in water

    According to the World Health Organization (WHO) and UNICEF’s 2015 Progress on Sanitation and Drinking Water report almost 700 million people around the world don’t have access to clean drinking water [1]. Poor water quality is beginning to return to the developed world too. The strain of population growth, intensified agricultural practices and continued industrial expansion have are ...

  • Drinking Water Analysis Guide

    Public Water Systems (PWS), regulated by the United States Environmental Protection Agency (USEPA), provide drinking water to 90% of Americans. Water systems and laboratories testing drinking water for Safe Drinking Water Act (SDWA) compliance must be certified and must use USEPA approved methods, which are developed by the USEPA, other government agencies, universities, consensus method ...

  • Analysis of PCB in water using the Dtech test system

    MATRIX: Water ANALYTE: PCB LIMIT OF DETECTION: Color Card: 100 ppb (as aroclor 1254), DTECHTOR meter: 50 ppb (as aroclor 1254) BACKGROUND: This application describes a field screening method for determining PCB concentrations in water. A 1:2 dilution of the sample in methanol is made to minimize adsorptive losses. A ...


  • Exergy analysis of an ammonia?water absorption system

    Exergy analysis of an ammonia?water absorption system for cooling applications is presented in this paper. Exergy destruction rate and heat rate in each component of the system are evaluated. From the results obtained it can be concluded that the evaporator and condenser heat loads and exergy destruction rate are less than those of the absorber and generator. This is due to the heat of mixing in ...

  • An enquiry into the place of systems analysis in the politics of water and the environment

    In many jurisdictions, the participation of stakeholders in decisions concerning their environment, and their water environment in particular, is still carried out, if at all, on an ad hoc basis. This paper envisions a legislative structure that allows a natural participation by the people in decision-making. While systems analysis and models may inform opinion in the ideal Legislature, ...

  • Analysis of PCB in water using the envirogard test system

    MATRIX: Water ANALYTE: PCB LIMIT OF DETECTION: Aroclor 1248: 1 ppm Aroclor 1260: 2 ppm Aroclor 1242: 2 ppm Aroclor 1254: 1.1 ppm BACKGROUND: This application describes a field screening method for determining PCB concentrations in water. A chemical reaction is induced that causes a color change ...


  • Guidelines for transient analysis in water transmission and distribution systems

    All water systems leak, and many supply systems do so considerably, with water losses typically of approximately 20% of the water production. The IWA Water Loss Task Force aims for a significant reduction of annual water losses by drafting documents to assist practitioners and others to prevent, monitor and mitigate water losses in water transmission and distribution systems. One of the causes of ...

  • An Analysis of Water Governance in Kibera, Kenya

    Abstract Populations in urban slums continue to rise due to the relatively affordable shelter provision. Most slums are neither planned nor formal and therefore lack basic service delivery. Despite the fact that the majority of inhabitants in these slums are low-wage earners, they are forced to pay more for basic needs such as water than their neighbours in ‘affluent’ and ‘well-to-do’ ...


  • Life Cycle Analysis of Water Networks

    Abstract Water authorities around the world are faced with the problem of ageing distribution networks and often only limited historical data on which to base a sound long term, cost efficient replacement policy. The LICAN approach to whole of life costing is introduced and a hypothetical case study is used to demonstrate the importance of such an approach. A selection of pipe networks ...

  • 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 ...

  • The influence of the existing network layout on water distribution system redesign analysis

    The methodologies usually adopted in water distribution system redesign problems consider the topology of the network as an input fixed datum; optimisation solely allowing for the duplication/substitution of existing components. In order to contribute to the identification of optimal solutions that may lead to a lower risk of failure to supply the required water, together with a lower redesign ...

  • Clustering analysis of water distribution systems: identifying critical components and community impacts

    Large water distribution systems (WDSs) are networks with both topological and behavioural complexity. Thereby, it is usually difficult to identify the key features of the properties of the system, and subsequently all the critical components within the system for a given purpose of design or control. One way is, however, to more explicitly visualize the network structure and interactions ...

  • Earthquake proofing of water treatment plants through seismic system risk analysis

    In Japan, earthquake resistance improvement (earthquake proofing) of drinking water infrastructure is not as developed as for other types of infrastructure such as gas and electricity. To facilitate earthquake proofing, it is important for water utilities to encourage customers to better understand its importance and effectiveness. So that water consumers could instinctively understand the ...

  • Comparative analysis of the outflow water quality of two sustainable linear drainage systems

    Three different drainage systems were built in a roadside car park located on the outskirts of Oviedo (Spain): two sustainable urban drainage systems (SUDS), a swale and a filter drain; and one conventional drainage system, a concrete ditch, which is representative of the most frequently used roadside drainage system in Spain. The concentrations of pollutants were analyzed in the outflow of all ...

  • Decision Analysis Applications for the Sustainability of Global Urban Water Resources and Drainage Systems

    ABSTRACTWater is one of the most vital elements needed for life. In many countries water supplies, especially for critical drinking water, are either being depleted or polluted. Too often these problems are magnified due to the lack of reliable drainage systems that provide proper stormwater and sanitary sewage collection and treatment of human generated wastewater. ...

  • System dynamics analysis of water supply and demand in the North China Plain

    Water resource carrying capacity (WRCC) is an important metric for regional sustainable development in China. It is defined as the difference between the total water supply and demand. The North China Plain (NCP) currently faces a serious water shortage if the WRCC is not managed at a sustainable level. This study focuses on applying system dynamics (SD) methodology to evaluate different water ...

  • Investigation and analysis of college's water system: the case of Northeastern University

    To date there have been many studies of water system optimization which were focused on the water use performance of industrial, regional, and urban areas from a macro-perspective. However, water system optimization colleges and universities are rare, though the amount of water consumption is huge in higher education institutions. We applied a water extended input–output model to investigate ...

  • Logistic regression analysis to estimate contaminant sources in water distribution systems

    Accidental or intentional contamination in a water distribution system (WDS) has recently attracted attention due to the potential hazard to public health and the complexity of the contaminant characteristics. The accurate and rapid characterization of contaminant sources is necessary to successfully mitigate the threat in the event of contamination. The uncertainty surrounding the contaminants, ...
