  • Experimental investigation of leak hydraulics

    In recent decades the hydraulics of leaks, i.e. the definition of the relationships linking the hydraulic quantities in pipes with leaks, has received increasing attention. On the one hand, the definition of the relationship between the leak outflow and the relevant parameters – e.g. the leak area and shape, the pressure inside the pipe and outside the leak, and the pipe material ...

  • Oil in frac water testing

    The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the wa-ter. Waiting for remote laboratory results can take several days to a week. The InfraCal TOG/TPH ...

  • Leak behaviour in pressurized PVC pipes

    The correct definition of the leak law, i.e. the relationship between the leak outflow, the total head at the leak and other relevant parameters such as the pipe material, can seriously affect the accuracy of the numerical models used for the management of water distribution systems, either if they are used to forecast the leakage reduction by pressure management or to locate and size the leaks ...

  • Comparison of dye testing and electrical leak location testing of a solid waste liner system

    Abstract: Dye tracing and electrical leak location testing were independently conducted to detect and locate leaks in the primary geomembrane liner of two cells in a municipal landfill. Despite extensive quality control and quality assurance programs, water in the leak detection zone after construction indicated that the primary liner had a leak. Fluorescein dye tests were conducted by placing a ...

  • Apartment Water Test - Case Study

    We had successfully mitigated this exact situation at another property (Family Tree Apartments] which also had extensive pin hole leaks and water heater failures. Based upon this prior exceptional success, it was clear that the H20 Solutions USA, LLC team was again needed to engineer a solution. H20 Solutions USA, LLC is analysis revealed that the water supply in Greenfield, CAis very hard at 18 ...

  • Is your Plant as tight as you think? Leak Detector for extremely toxic Gases, a Field Test Report

    Leak detection of commodity gases in chemical plants is a day-to-day practice. The sensor technology available for this application is field proven and reliable. No question about it, existing sensors will do the job. However, in plants manufacturing or handling extremely toxic substances, the picture is different. For example, take phosgene. The existing sensor technology for leak detection ...

  • Mancomunidad de la Comarca de Pamplona (MCP) Identifies 4 Leaks Using Inline Leak Detection

    Around the world, leaking water pipelines represent a major resource and financial loss for utilities. It is estimated that in some places, Non-Revenue Water exceeds 50 percent. In terms of financial losses, the World Bank estimates that NRW costs utilities worldwide about US$14 billion annually. By reducing these losses by half in areas with the highest NRW, it is estimated that US$2.9 billion ...

  • Importance of Air & Water Testing in Indoor Pools

    Have you ever wondered why your eyes hurt or why you have a cough after swimming at an indoor pool? We all assume that it’s from too much chlorine in the pool but that is false! If the pool staff doesn’t regularly test and monitor both the air and water indoors, the environment becomes very toxic and unsafe to everyone in the building. Water is an essential ingredient for all life as ...

  • Leak detection by inverse transient analysis in an experimental PVC pipe system

    Leakage reduction in water supply systems and distribution networks has been an increasingly important issue in the water industry since leaks and ruptures result in major physical and economic losses. Hydraulic transient solvers can be used in the system operational diagnosis, namely for leak detection purposes, due to their capability to describe the dynamic behaviour of the systems and to ...

  • Enhanced Geomembrane CQA through proper application of geomembrane leak location surveys

    Abstract Historically, geomembrane construction quality assurance (CQA) has focused on destructive testing of welded seams to verify seam strength and integrity. Paradoxically, seams are not subject to significant stress and practically never fail in service, while holes and construction damage in the geomembrane are a much more widespread problem. The historical approach fails to evaluate ...

  • Case Study - Amistad Dam: Scan for Leaks in Earthen Dam

    At the Amistad Dam site an investigation was made with a 56 electrode STING/Swift system to determine the location of leaks which have effectively drained the giant dam of water. As it was not immediately obvious which array type would return the best data three different arrays were recorded on the same electrode layout. The resulting three 2D profiles show both similarities and differences. The ...

  • Locating Leaks in Geomembrane Liners of Landfills Covered With a Protective Soil

    ABSTRACT The electrical leak location method was used to locate leaks in the geomembrane liners of single-lined and double-lined landfills covered with a protective soil cover. The landfills ranged in size from 0.40 hectare (one-acre) to 3.2 hectares (eight-acre). Water in the leak detection system under the primary liner indicated the primary liners were leaking. The principal of ...

  • Development of a long duration, free swimming, inline acoustic leak detection inspection tool

    Abstract Acoustic leak detection inspection tools have become a common technique to identify minute pipeline leakage before the leak and the defect producing it can become a larger problem or even a rupture level event. While these inspection tools only identify small ...
