  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

  • Water testing 101: TDS

    According to Wikipedia, total dissolved solids (TDS) is defined as “the combined content of all inorganic and organic substances contained in a liquid that are present in a molecular, ionized or microgranular suspended form.” The article goes on to state that “total dissolved solids are differentiated from total suspended solids (TSS) in that the latter cannot pass through a ...

  • Stainless steels within desalination for reliable water supply

    To assure sustainable water production, the materials used in desalination plants need to perform for many decades without failures. During the last years, duplex - austenitic-ferritic - stainless steels have been selected for several desalination projects due to their unique combination of mechanical properties and corrosion resistance. Price stability of those grades, as a consequence of a ...

  • Simulating development strategies for water supply systems

    ABSTRACT The objective of this paper is to point out existing risks of current design and management strategies in water supply systems and to identify possible ways of designing and operating schemes which minimize these risks. This paper is motivated by the observation that existing design principles and engineering rules (best practice) seem to cope insufficiently or even conflict with ...

  • Testing and developing energy harvester systems for operation of energy-self-sufficient measurement and control units in drinking water supply

    In recent years, wireless measurement and control units have become more popular for monitoring water distribution systems in the drinking water supply. Electric power supply for a higher number of devices through fixed connections to the public electrical grid is technically complex and requires large investments. Powering monitoring devices, which are installed in areas where electrical ...

  • Deterioration in water quality from supply chain to household and appropriate storage in the context of intermittent water supplies

    Many water providers in urban developing country contexts have to supply the water intermittently due to the disparity between rapidly growing demand and investment in supply infrastructure. This can lead to water quality risks such as ingress of polluted groundwater and unsafe household storage. This study has investigated the common risks and possible alternative solutions down the supply chain ...

  • Laboratory Management - Integrated Sampling the Key to Safe Water Supply

    Leading water suppliers use Laboratory Information Management Systems (LIMS) to integrate the sample collection and analysis process, helping to maximize the efficiency of these programs. Drinking water suppliers around the world face unique challenges: They must deliver the most essential ingredient for life on a grand scale, while also navigating complex issues surrounding public safety, ...

  • River safe yield with the constraint of a contracted rectangular weir for surface water supply

    Aydin et al. introduced the weir velocity concept in 2011 for discharge measurement in contracted rectangular sharp-crested weirs. Gharahjeh et al. further reinforced this formula in 2015 to allow discharge to be computed using only weir velocity and crest width. These newly introduced expressions are tested and demonstrated to determine surface water yield of Tapah River in ...

  • 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 ...
