  • Overview of Rotating Disc Electrode (RDE) Optical Emission Spectroscopy for In-Service Oil Analysis

    Introduction The basis of modern oil analysis is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. Whatever else an oil lab may measure, a multi-elemental analysis is the core of in-service oil analysis. This paper gives an overview of Rotating Disc Electrode Elemental Spectroscopy and its ...

  • Case study - Low-flow groundwater sampling on a nuclear site

    Nuclear licensed site use of low-flow groundwater sampling shows: Reduced time, reduced quantity of purge water – both thus reducing cost - and reduced risk of operator contact especially with potentially radioactive-contaminated purge water thanks to a self-contained enclosed system. One of the biggest headaches on site is the purge water and the expense of getting rid of it – after ...

  • Pilot-Scale Biofilter Test for Treating Zimpro Odors

    The thermal sludge conditioning process of U.S. Filter/Zimpro Corporation, Rothschild, Wisconsin (Zimpro process) is primarily used to improve dewatering characteristics of the waste sludge. The process entails a partial breakdown through oxidation and hydrolysis of complex, high molecular weight organic compounds, such as, proteins, fibers, carbohydrates, and fats. The partial breakdown of ...
