  • Non-Revenue Water – A Growing Issue for Water Utilities

    Each day, billions of gallons of water are lost worldwide to various factors, including leaks, water main failures, theft and metering inaccuracies. Not only does this represent the waste of a precious resource that many people do not have reliable access to, it also represents a massive amount of lost revenue for the utilities that provide water services. In developed nations, ...

  • Algorithmic network monitoring for a modern water utility: a case study in Jerusalem

    We report on the design, deployment, and use of TaKaDu, a real-time algorithmic Water Infrastructure Monitoring solution, with a strong focus on water loss reduction and control. TaKaDu is provided as a commercial service to several customers worldwide. It has been in use at HaGihon, the Jerusalem utility, since mid 2009. Water utilities collect considerable real-time data from their networks, ...

  • Leak detection in semiconductor fab gas processes

    Problem Statement Often times in semiconductor fabs moisture levels are monitored to ensure that products aren’t damaged by excess moisture in the process. If there are above normal levels of moisture, pinpointing the source of that moisture can be difficult. The moisture could be evolving from impurities in gas tanks or leaks in the sampling lines. One way to avoid downtime ...

  • Controlling odors from creosote utilizing foam-based technology

    From approximately 1910 until the mid-1950s, a creosote plant operated on a 50 acre site in Manville, New Jersey. During its operation, the wood treatment facility treated railroad ties with creosote and discharged the excess creosote via canals to two waste lagoons located on the site. After treatment, wood was stored in areas of the site where excess creosote dripped onto surface soils and ...

  • 3 Water Utilities that Lowered their Arsenic Levels with AdEdge

    Finding an appropriate solution to address arsenic in raw water can be challenging for utilities. Studies have shown that when ingested in high concentrations, it is linked to cancer in the skin, lungs, bladder and kidney, and can cause significant skin changes, such as thickening and pigmentation, as well as other health issues. For this reason, the ...

  • Detecting Arsenic in Soil using Field Portable X-Ray Fluorescence

    Abstract Rapid, accurate on site determination of arsenic and heavy metal levels in soil is a powerful tool in efforts to rebuild and revitalize abandoned and under-utilized industrial properties. The EPA is actively spearheading initiatives to encourage assessment, clean-up and re-use of these industrial properties. In the case of heavy metals (often the eight RCRA metals Pb, As, Cd, ...

  • Refrigerant leak detection is heavily regulated by government agencies

    Refrigerant leak monitoring in refrigeration and air-conditioning (RAC) systems and heating, ventilation and air conditioning (HVAC-R) equipment is very challenging, even for the most skilled HVAC-R technician. The leak could be well concealed from view in tubing, a system component, or in an operating or safety control component. With the Environmental Protection Agency (EPA) laws documented ...
