  • What’s the difference between distilled and deionised water?

    “Pure” water is used in all types of laboratories for a range of uses – from making up calibration standards to cleaning and even in the rinse cycle in some laboratory glasswashers for a pure clean. There are different types of purified water available – but what is the difference? Distilled water Distilled water is simply made by heating water to ...

  • Brackish water treatment for reuse using vacuum membrane distillation process

    The availability of fresh water is vital for all human activities and in particular for improving living conditions, health and overall well-being. Pressure on scarce fresh water resources can be reduced by treating and reusing brackish water by advanced membrane treatment technologies. In this study, brackish water originating from effluent discharge of a local coal mine, seawater, groundwater ...

  • Effect of Leaching from Filters on Laboratory Analyses of Collective Organic Constituents

    Membrane and glass fiber filters are widely used in laboratory water and wastewater analyses. During sample filtration, some filters release organic compounds, which may interfere with organic analyses. This research investigated the interferences due to organic leaching in the determinations of dissolved organic carbon, biodegradable dissolved organic carbon, soluble biochemical oxygen demand, ...

  • 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 ...

  • Falling Oil Price Forces Operators to Find Cost Savings in Water Management

    When oil prices were 80 to 100 dollars per barrel, water management costs were high, but they were tolerable when money was flowing profitably. However, as today’s falling price nears 40 dollars, water related costs are still high and only exacerbate widespread industry losses. The 150 US-based companies tracked by Oil & Gas Journal and Oil & Gas Financial Journal reported that ...
