  • With the Primozone ozone installation alands water can supply perfect drinking water even during The Summer, when The Island Is Filled With Tourists - Case study

    The Primozone ozone solution was installed at the Åland Water WTP in June 2007 and has been working perfectly ever since then. The plant supplies 475 m³/h of drinking water to the population of Mariehamn, which is the larger part of Åland’s 27.000 inhabitants, and which doubles during the summer season. Åland is an archipelago of 6.500 islands. The process ...

  • Do natural spring waters in Australia and New Zealand affect health? A systematic review

    Therapeutic use of spring waters has a recorded history dating back to at least 1550 BC and includes both bathing in and drinking such waters for their healing properties. In Australia and New Zealand the use of therapeutic spring waters is a much more recent phenomenon, becoming a source of health tourism from the late 1800s. We conducted a systematic review aimed at determining the potential ...

  • Caries affected by calcium and fluoride in drinking water and family income

    Water quality and socioeconomics influence caries in populations. This study broadens previous studies on how caries is associated with fluoride and calcium in drinking water and with family income by quantifying the combined effect of the three independent variables. The effects of calcium and fluoride can be described as independent effects of the two ions or, alternatively, in the form of ...

  • 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 ...

  • Rotork’s RHS solves valve access issue at water treatment plant

    Recent rehabilitation at the drinking Water Treatment Plant #2 in Olathe, Kansas, USA, has included the installation of Rotork IQ3 intelligent electric valve actuators to replace electric actuators from another manufacturer. In the gravity filter plant, 18 butterfly valves are situated in an area beneath a walkway which made it difficult to access and operate the old actuators. With the new ...

  • Calculating chemical speciation, pH, saturation index and calcium carbonate precipitation potential (CCPP) based on alkalinity and acidity using OpenModelica

    Of the most commonly used calcium carbonate (CaCO3) saturation indices, the Calcium Carbonate Precipitation Potential (CCPP) most accurately describes CaCO3 precipitation and dissolution. This paper illustrates how to write an OpenModelica programme that calculates the CCPP and other key water parameters starting from total alkalinity and CO2-acidity. It describes the ...

  • Brackish Water as a Resource

    There’s a great deal of talk and debate about the value of treating brackish water, or water that is more saline than fresh water, but not quite as saline as seawater. Brackish water can result from the mixing of seawater with fresh water, as in surface waters such as estuaries or other watery ecosystems, or it can occur underground in aquifers. Salinity Levels Although ...

  • Practical evaluation of inorganic contaminant presence in a drinking water distribution system after hydraulic disturbance

    The accumulation of loose deposits in a drinking water distribution system (DWDS) is a potential risk for water quality. In this work, hydraulic disturbance was simulated in different areas of a large DWDS. The water quality features before and after the disturbance were compared, and the solid deposits captured from different experimental sites were characterized. The results showed that the ...
