  • A solution to fracturing water supply and disposal issues

    “Water, water, everywhere, Nor any drop to drink.” –The Rime of the Ancient Mariner, Samuel Taylor Coleridge Many topics of conversation among oil and gas industry professionals are predictable – oil price trends, the “great shift change” imperiling the available workforce, and production quotas and caps from OPEC. Yet one pressing topic among those developing ...

  • Health effects of disinfection by-products in Australian drinking waters

    The disinfection of drinking water has greatly diminished the occurrence of diseases known to be caused by water-borne pathogens, but technological advances subsequent to the initial discovery of chloroform in 1974 have enabled the identification of a plethora of Disinfection By-Products (DBPs), particularly trihalomethanes (THMs), that may have injurious health effects on humans. DBPs are widely ...

  • Times are changing: Wastewater as a resource

    Times are definitely changing. It used to be that wastewater from whatever source – domestic, agricultural, industrial – was something to collect and pipe away as quickly and efficiently as possible. There was more water coming out of the ground or falling from the sky, so why bother investing time and money cleaning water that had already been used? Now, thanks to issues like ...

  • UV Minimises Risks for Major Food Retailers

    For many years, one of the UK’s largest food manufacturers has made it their business to be the best at producing all manner of bespoke cooked and raw, ready-to-eat vegetables and carbohydrates for their customers, who include chilled food manufacturers, food-to-go operators and, of course, major supermarkets. Being the best means not only complying with food quality standards set by ...

  • 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 ...

  • Biocorrosion in drinking water pipes

    Copper is widely used in drinking water distribution systems due to its relatively low cost and favorable mechanical properties. However, copper corrosion may generate copper concentrations exceeding the thresholds prescribed by international drinking water standards. In-situ measurements performed in an actual system found that the copper mass released under flowing water conditions (pipe ...

  • Eutrophication linked to disinfection - by products problem in drinking water production

    Eutrophication is one of those big problems that cause water quality degradation. Presence of cyanobacterial toxins and climate change impacts would degrade water quality towards the worst. In regard to the mentioned problems, disinfection-by products strongly act as a consequence of drinking water production. ...

  • 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 ...

  • Report to Congressional Requestors: Drinking Water

    Every day in the United States, at least 2 billion gallons of fluids are injected into over 172,000 wells to enhance oil and gas production, or to dispose of fluids brought to the surface during the extraction of oil and gas resources. These wells are subject to regulation to protect drinking water sources under EPA’s UIC class II program and approved state class II programs. Because much ...

  • Transformation products of pharmaceutically active compounds during drinking water ozonation

    Ozonation and ozone-based advanced oxidation processes have been shown to be effective in the oxidation of several pharmaceutically active compounds (PhACs) routinely detected in surface waters. Under typical operating conditions of these processes, most of the parent compound oxidized is expected to lead to the formation of transformation products (TPs). For a target ozone exposure, the ...

  • Monitoring of chlorination disinfection by-products and their associated health risks in drinking water of Pakistan

    This study reports the baseline data of chlorination disinfection by-products such as trihalomethanes (THMs) and their associated health risks in the water distribution network of Islamabad and Rawalpindi, Pakistan. THM monitoring was carried out at 30 different sampling sites across the twin cities for 6 months. The average concentration of total trihalomethanes (TTHMs) and chloroform ranged ...

  • gaiasafe filter products for drinking water purification - Case Study

    Problem In some water works chlorination of drinking water is used to eliminate mikrobes. Chlorinated water may have disagreable taste and smell. Some water works use aluminium salts to clean the water. This leads to low concentrations of aluminium in drinking water. Today it is known that aluminium may be toxic to men. Old piping installations inside or outside private homes often where ...

  • Safe drinking water and waterborne outbreaks

    The present work compiles a review on drinking waterborne outbreaks, with the perspective of production and distribution of microbiologically safe water, during 2000–2014. The outbreaks are categorised in raw water contamination, treatment deficiencies and distribution network failure. The main causes for contamination were: for groundwater, intrusion of animal faeces or wastewater due to ...

  • 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 ...

  • Electronic Water Treatment Provides a Clean Line for Food and Drink Production

    The USA’s food and drink producers spend billions of dollar’s each year in downtime, increased energy bills and the early renewal of capital equipment caused by hard water limescale blocking lines and leaving calcium carbonate deposits on water fed equipment.  Scale and sludge formation are the result of the precipitation of compounds that are ...

  • Disinfection by-products in drinking water – a case study on Calgary, Alberta, Canada

    Disinfection by-products (DBPs) have been monitored in Calgary's drinking water for approximately 15 years. The variability of the DBPs has typically exhibited similar patterns over the period of monitoring. Due to the nature of the surface waters supplying the water treatment plants, the level of DBPs was largely influenced by surface runoff events where the level of natural organic matter (NOM) ...

  • 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 ...

  • The effect of the surface-to-volume contact ratio on the biomass production potential of the pipe products in contact with drinking water

    The biomass production potential (BPP) test is a semi-static test for assessment of microbial growth promoting properties of construction products in contact with drinking water (CPDW). In 2003 the test was selected for incorporation into a scheme for acceptance of CPDW in the framework of implementation of the European Construction Product Directive and Drinking Water Directive. The pass/fail ...
