  • TOC Analysis for Standard Methods 5310B: High-Temperature Combustion Method

    Introduction Total Organic Carbon (TOC) is a rapid method that analyzes for organic carbon and expresses the result as the amount of carbon found. It is a non-specific method unable to distinguish between various organic species and only indicates that organic carbon compounds are present. Organic carbon analyzers operate by the determination of the amount of total carbon present in a ...

  • The Future of Drinking Water

    Predicted future growth in population numbers and rising sea levels mean demand for drinking water will continue to increase just as the natural availability of freshwater decreases. It is likely that brackish groundwater will be an important source of drinking water in the future, but the current methods used to produce fresh water from this source are expensive in terms of their energy use and ...

  • Drinking Water Standards

    The most important point of departure for drinking water standards is the World Health Organisation Guidelines for Drinking Water Quality. These are widely used throughout the world with the exception of parts of North America. WHO’s Guidelines have evolved over a period of 50 years from standards to guidelines, reflecting the fact that they have no legal force. The WHO emphasises that it ...

  • Water, water everywhere: But is there enough to drink?

    Original story at MIT News At MIT, experts address the challenges of supplying clean, safe water to a growing world population. The challenge of supplying clean, safe drinking water to an expanding world population comes down to money, MIT economist Franklin Fisher ...

  • The South Australian Safe Drinking Water Act: summary of the first year of operation

    The Safe Drinking Water Act 2011 was introduced in South Australia to provide clear direction to drinking water providers on how to achieve water safety. The Act requires drinking water providers to register with SA Health and develop a risk management plan (RMP) for their water supply that includes operational and verification monitoring plans and an incident notification and communication ...

  • Natural Disaster Recovery & Drinking Water

    Clean water is one of the fundamental pillars of modern civilization, and a major priority for local and municipal government.  When disaster – hurricanes, tornadoes, earthquakes – strikes, one of the first priorities is to rehabilitate water treatment and distribution systems.  Water main and pipe breaks, pressure loss, and backflow can all act to introduce external ...

  • Metals and Related Substances in Drinking Water

    The contamination of drinking water by metals and metalloids can occur throughout the “source to tap” production and delivery system. The major problems are with arsenic, iron, nickel and lead. Problems can also occur with aluminium, copper, manganese, selenium and sodium. Arsenic, iron and lead are core parameters in the UN/WHO Protocol on Water and Health. The spectrum of ...

  • The influence of city water consumption on the water balance and quality of drinking water supply with implications for altered operating rules

    In the period 1990–2006, the decrease in water consumption of Tallinn, the capital of Estonia, determined both the input and output of the water balance of Lake Ülemiste, the drinking water reservoir of the city as well as its hydraulic retention time (HRT). In 2006, the city's water consumption accounted for only a quarter of that in 1990.The role of regulated inflow in the water balance ...

  • 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 ...

  • 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 ...

  • Nitrogen and phosphorus removal from secondary effluent using drinking water treatment residuals fixed-bed column with intermittent operation

    This work aims to explore a novel intermittently operated fixed-bed column with drinking water treatment residuals (WTR) as main medium to remove nitrogen (N) and phosphorus (P) from secondary effluent under different hydraulic loading rates (HLRs). The results showed that the WTR was beneficial for N removal and the average removal efficiency reached 59%. The denitrification was the ...

  • Experiences with the practical implementation and operation of biological nitrification for a small-scale drinking water treatment plant

    The implementation and evaluation of biological nitrification as a possible treatment option for the small-scale drinking water supply of a rural Upper Austrian community was investigated. The drinking water supply of this community (average system input volume: 20 m3/d) is based on the use of deep anaerobic groundwater with a high ammonium content of geogenic origin (up to 5 mg/l) which must ...

  • Virus contamination from operation and maintenance events in small drinking water distribution systems

    We tested the association of common events in drinking water distribution systems with contamination of household tap water with human enteric viruses. Viruses were enumerated by qPCR in the tap water of 14 municipal systems that use non-disinfected groundwater. Ultraviolet disinfection was installed at all active wellheads to reduce virus contributions from groundwater to the distribution ...

  • Aging evaluation of medium-pressure mercury lamps under typical operating conditions for drinking water disinfection applications

    Little is known regarding how medium pressure (MP) ultraviolet (UV) lamps age under typical operating conditions, yet a number of assumptions regarding lamp aging are utilized when UV reactors are validated, often as unfounded approximations. This study was designed to evaluate the aging of MP UV lamps utilized with a closed-vessel UV reactor technology for drinking water disinfection ...
