  • Application of Lab-on-a-chip Technology in Water Analysis

    The Important of Water Analysis Water analysis is essential to ensure its quality or to detect pollutants that should be removed by water treatment. However, water quality does not mean making the water suitable for human consumption; it depends on its end use. For example, completely different quality standards are applied in case of industrial water compared to those ...

  • Oil Analysis for Hydraulic Systems

    Hydraulic systems are used in industrial, mobile and aviation applications to transmit power to operate equipment. They are incredibly efficient, compact, and lightweight relative to a mechanical equivalent. Hydraulic fluids transmit force in the system, and as such are carefully chosen by the system maker. Chemical stability, high flash and fire points, viscosity, and oxidation resistance are ...

  • CASE STUDY - Setup and calibration of a three-dimensional numerical multiphase model for design of in-situ remediation of jet fuel with surfactant

    BACKGROUND Storage and pumping of jet-fuel have caused a severe contamination of soil and groundwater at a military facility in Denmark. The contamination was detected in 2001. The Danish Defence has conducted 3 a series of investigations and set up a skimmer system, that has recovered approximately 25 m of jetfuel. In 2005, the recovery stopped, and the remaining jet-fuel is trapped as a ...

  • Match, don't mix: implications of institutional and technical service modalities for water governance outcomes in south Indian small towns

    This paper seeks to contribute to the limited literature on water governance in small towns in India. For assessing water governance, we propose a broad framework encompassing adequacy and affordability, equity, sustainability and responsiveness. Analytically, the concept of ‘service modality’ is expanded to include not only institutional arrangements but also water resource deployment, and ...

  • Organic matter removal in bio-filters to achieve biologically stable water downstream of the process

    Organic removal contaminants reclamation has increased over the past years as it has many advantages over other treatments. Product water from water treatment plants can be chemically complex resulting in physical and biological changes during transportation in the distribution systems. The general aim of this study was to evaluate the effectiveness of biofilters for reducing the concentration ...

  • Comparative analysis of two low cost point-of-use water treatment systems

    The study examined two low-cost point-of-use water treatment systems developed in respect of bacterial and particulate removal when exposed to surface water for three months. Bacterial removal efficiency was estimated using E. coli and fecal coliforms, while particulate reduction efficiency was estimated by determining turbidity and total suspended solids (TSS). The systems investigated were ...

  • Assessing the spatial pattern of iron in well water from a small central Florida community

    Iron is one of the most common elements in the Earth's crust, which corresponds to it being a common constituent in drinking water supplies. Residents of Bithlo, an unincorporated community in east-central Florida, have observed that their drinking water tastes like metal and stains clothing and teeth. An evaluation of water samples collected from over 200 private drinking water wells revealed ...
