  • New Process Gas Analyzer for the Measurement of Water Vapor

    KEYWORDS TDLAS, WMS, Laser Spectroscopy, Water Vapor Measurement, Gas Analyzer ABSTRACT A new analyzer for the measurement of water vapor concentration based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) was developed. The water-vapor line at 1854-nm was selected for the measurement, and the performance of the system was evaluated on different ...

  • Using FTIR spectroscopy to measure hydrocarbon pollution in water

    According to the World Health Organization (WHO) and UNICEF’s 2015 Progress on Sanitation and Drinking Water report almost 700 million people around the world don’t have access to clean drinking water [1]. Poor water quality is beginning to return to the developed world too. The strain of population growth, intensified agricultural practices and continued industrial expansion have are ...

  • Ultrapure water – The standard for resistivity measurements of Ultrapure water - Case Study

    Abstract For years, resistivity/conductivity2 instrumentation has been used as a reliable indicator of ionic water quality, especially for ultrapure water (UPW). Traditionally, the instrumentation is procured, installed, powered up, and perhaps connected to a PLC, strip chart recorder, or a LAN. After that, the instrument and sensor receive no attention until a problem arises. Today, ...

  • ppb Dissolved oxygen measurement

    Dissolved oxygen (D.O.) measurement is one indicator of water quality because oxygen is a common element contributing to corrosion reactions. This corrosion reaction provides the need for low level D.O. control since dissolved oxygen is responsible for costly replacement of piping and equipment by corrosive attack on metah. what is Dissolved Oxygen? Dissolved axygan (D.O.f is the ...

  • Flood Resilience Measures

    Flood risk management is a top priority, exacerbated by the perception that flood risk has increased during the last two decades in many regions. There are two hypotheses for such changing patterns: Changes in climate, e.g. the sequencing of extreme wet and dry periods, leading to a greater magnitude and/or frequency of hydrological extremes (Huntington 2006); and ...

  • Continuous Improvement in Automotive Manufacturing: Hendersons Automotive Group

    Cleaner production measures introduced in 1992 by Hendersons Automotive Group have resulted in annual savings of $270,000. The measures cost a total of $309,000, and paid for themselves in only 18 months after implementation. The biggest investment of $235,000 involved the commissioning of a seat slide pre-treatment system, while the others were good housekeeping measures which have helped raise ...


  • Quantification of sewer leakage by a continuous tracer method

    Water authorities interested in the evaluation of the structural state of a sewer must quantify leakage to plan strategic intervention.
