  • Controlling Scale Deposition and Industrial Fouling

    It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance ...

  • Controlling scale in water systems helps prevent legionella

    The Legionella bacterium, Legionella Pneumophila (LP), the fundamental agent of Legionnaire’s Disease, is a water-based organism, which causes infection when inhaled in an aerosol form. Legionnaires' Disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness ...

  • Controlling scale deposits in the pulp & paper industry

    The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product.  As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water ...

  • Impact of Corrosion on Electronic Equipment

    Corrosion is the destruction of metals through reaction with compounds in their environment. It is a natural process because compounds such as oxides, sulphides and chlorides are formed and these are stabler than pure metals. Electronic circuits and components are omnipresent in our environment. Until recently, the thousands of soldered joints that an electronic circuit contains were ...

  • The mystery of electronic water treatment unveiled

    The problems of scale are well known to those living and working in "hard" water areas. Scale is the undesirable consequence of water supplies becoming super-saturated with dissolved minerals.  These problems are of greater significance if found in industrial water systems and commercial buildings. Scaling problems commonly occur, even in "soft" water areas, when a fluid stream is ...

  • Preventing scale in recreational vehicles and motorhomes

    Over 80% of North America is affected by hard water, which is a major problem for the owners of RVs and Motorhomes.  Consequently, whatever State you are visiting in your RV, or if you have a motorhome permanently located in a hard water area, limescale will clog pipes, ruin appliances, destroy faucets and cloud glassware. The award-winning, patented, Scalewatcher water-conditioner, from ...

  • Scalewatcher Removes Scale from Baptistery

    The Church of Christ in Shiner, Texas is no longer experiencing scale build up on its baptistery immersion tank following the installation of the computerized, electronic, water-conditioner Scalewatcher from Scalewatcher North America. The Scalewatcher system has also improved the clarity of the water, enhanced the operation of the heater and drastically reduced the amount of chlorine required. ...

  • Electronic Water Treatment Reduces Fouling In Reverse Osmosis

    Reverse Osmosis (RO) is used in processes requiring high-quality, purified water, such in semi-conductor processing or biochemical applications and can be used to treat boiler feed water, industrial wastewater or process water. A water purification technique, it reduces the quantity of dissolved solids in solution. RO uses waterline pressure together with energy consuming pressurizing pumps that ...

  • Electron-phonon coupling and heat dissipation in metal nanoparticles

    This review discusses electron-phonon (e-ph) coupling and heat dissipation in noble metal nanoparticles, specifically, how the time constants for these events depend on size. This has proven to be a difficult question for the e-ph coupling process. For example, results from our laboratory and others, show that for Au particles in aqueous solution the coupling between the electrons and phonons is ...

  • How often should you calibrate your scales?

    Weighing plays an integral part in a wide variety of industrial processes. A typical weighing system consists of a weight controller, a load sensor–based scale, and a programmable logic controller (PLC). To be reliable and accurate, weighing systems must be calibrated. But how often is enough? Old weighing systems included dials and pivots, springs, counterbalances, or levers, which ...

  • Eco-friendly Scalewatcher tackles scale in school building

    A school in Texas is benefiting from reduced salt and chemical usage following the installation of the computerized, electronic, water-conditioner Scalewatcher® from Scalewatcher North America.  The Scalewatcher system has proved so successful that the school authorities are proposing to install units in every building which will save the school authority thousands of dollars a year in ...

  • Large-scale synthesis of nanopowders by transferred arc thermal plasma

    The present work describes the preliminary results on large-scale synthesis and characterisation of copper (Cu) and aluminium nitride (AlN) nano powders by transferred arc thermal plasma technique. The transferred arc was used to vaporise the precursor materials (Cu, Al metal 99.9% pure). Nano particles are formed in the gas phase as a result of homogeneous nucleation. The vapours of Al were ...

  • Boiler Dissolved Oxygen Control

    DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate ...

  • Hydrogen Equivalents: Comparison of Simple Electron Donors to EHC In-Situ Chemical Reduction (ISCR) Reagents

    Biodegradation via reductive dechlorination processes occurs when microbes directly remove chlorine atoms from a chemical in order to derive energy from other organic compounds. This occurs under reducing, anaerobic conditions. A more effective remedial strategy, however, entails in situ chemical reduction (ISCR) using EHC as the reductant. As described herein, EHC™ is the patented combination of ...


  • Remediation of chlorinated ethenes, ethanes, and methanes in groundwater using carbon- and iron-based electron donor

    Field-scale pilot tests were performed to evaluate enhanced reductive dechlorination (ERD) of dissolved chlorinated solvents at a former manufacturing facility located in western North Carolina (the site).
