  • Importance of measuring UV transmittance (UVT) for UV disinfection

    UV disinfection systems disinfect water using UV light at the 254 nm wavelength. UV light at this wavelength actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as cryptosporidium and e-coli from reproducing and causing harm. UV Disinfection Dose and UV Transmittance (UVT) The effectiveness of a UV disinfection system is ...

  • Detailed off-gas measurements for improved modelling of the aeration performance at the WWTP of Eindhoven

    At wastewater treatment plants (WWTPs), the aerobic conversion processes in the bioreactor are driven by the presence of dissolved oxygen (DO). Within these conversion processes, the oxygen transfer is a rate limiting step as well as being the largest energy consumer. Despite this high importance, WWTP models often lack detail on the aeration part. An extensive measurement campaign with ...

  • Helplessly exposed to nature? How lightning storms can be measured

    Each day, there occur about 1,000 thunderstorms with 4-10 million lightning bolts worldwide. In average, 700 people per year are hit by such light discharges, of which 75% of the hits result in long-term damages. Between three and seven cases end fatal. The risk is particularly high in the open field and is fortunately decreasing. The reason for this is that we stay more often inside in cars and ...

  • Treatment of natural rubber processing wastewater using a combination system of a two-stage up-flow anaerobic sludge blanket and down-flow hanging sponge system

    A pilot-scale experiment of natural rubber processing wastewater treatment was conducted using a combination system consisting of a two-stage up-flow anaerobic sludge blanket (UASB) and a down-flow hanging sponge (DHS) reactor for more than 10 months. The system achieved a chemical oxygen demand (COD) removal efficiency of 95.7% ± 1.3% at an organic loading rate of 0.8 kgCOD/(m3.d). Bacterial ...

  • Beyond Incident Rates: Use the Power of Leading Indicators to Improve EHS Performance

    What if you were driving somewhere, and could only see backwards in the rear-view mirror? Sounds scary, but this is pretty much how traditional Environmental, Health and Safety (EHS) metrics like incident and injury rates have been used for decades to manage performance. Such lagging indicators measure what occurred in the past. They give you a good view of where you’ve been, but not where ...

  • Cam correlation analysis using Acoustic discharge measurement

    The low head hydro power plant in Wettingen, Switzerland, is in operation since 1933 and no effective cam optimization has been carried out up to now. The goal of the measuring campaign was to provide data enabling an economic study for a retrofit and upgrade project of the plant and the measurement of the efficiency improvement of turbines after refurbishment. The contribution discusses cam ...

  • The Power of the Moon

    The influence the moon has on life on earth is disputed. However, during an assignment in Southeast Asia, vibration experts from Sulzer were able to clearly confirm that the moon can even affect pumps. With its broad expertise, the Sulzer team was able to solve an unusual case of vibration. Southeast Asia is a key exporter of LNG (liquefied natural gas) to global markets, and it is ...

  • How to measure the direction of current harmonics?

    If the generation side of the point-of-common-coupling (PCC) is essentially an islanded setup consisting of a few specific generators, then the amount of harmonics resulting from the generation "source" can be readily identified in a mathematical fashion from the relative impedance on the generation side of the PCC compared to the combined impedance on the load side of the PCC. (The source of ...

  • Measuring SO2 ship emissions with an ultraviolet imaging camera

    Over the last few years fast-sampling ultraviolet (UV) imaging cameras have been developed for use in measuring SO2 emissions from industrial sources (e.g. power plants; typical emission rates ~ 1–10 kg s−1) and natural sources (e.g. volcanoes; typical emission rates ~ 10–100 kg s−1). Generally, measurements have been made from sources rich in SO2 with high concentrations ...
