  • Capturing biogas energy to increase your business profits while safeguarding the environment

    Methane is a biogas produced from swine or cow manure, as well as food processing and meat packing waste. Methane is a natural gas, that when left uncollected, contributes to the harmful greenhouse gases in the earth’s atmosphere. When biogas is captured under a cover and becomes concentrated, it creates a corrosive and toxic byproduct called hydrogen sulfide. The gas generates a rotten egg ...

  • Landfill Liners Vary by Application

    It was in 1991 that the Environmental Protection Agency promulgated its Criteria for Municipal Waste Landfills that set location restrictions, design and operating standards, groundwater monitoring requirements, corrective actions, closure requirements, and more for landfills. It was these rules that mandated that landfills be lined on the sides and bottom before waste is deposited and capped on ...

  • Frostbite And Hypothermia Hazards

    Hypothermia and frostbite can be two of the serious consequences of working outdoors in winter weather. Hypothermia is a dangerous lowering of the body’s temperature by exposure to cold or wet conditions. Actually, the air temperature doesn’t have to be particularly low to cause hypothermia – just getting wet and chilled can do the same thing. Hypothermia can be fatal. ...

  • The Advantages of a Box Welded Pond Liner

    There’s no time like the New Year for good intentions – and one which will pay dividends for many years to come is to create a garden pond. One of the first choices you’ll have to make is the type of liner to use. The material itself is a no-brainer – always use a synthetic rubber liner rather than polythene; synthetic rubbers are much tougher and longer lasting than the ...

  • How to fit a box-welded pond liner for a perfect water feature

    Box-welded pond liners are also commonly referred to as tailored-to-fit, bespoke, made-to-measure or tailor-made pond liners. All terms are recognised by professional landscapers and by pond liner manufacturers. Suited to formal pond designs, a box-welded pond liner provides the best fit with no unsightly seams or folds. A ...

  • The effect of sponge liner on the performance of simple solar still

    In conventional solar stills, a part of the radiation is reflected by the inner wall surfaces to the still components and the remaining energy is stored by itself. The main objectives of this experimental study are: 1) to utilise the energy available on the inner wall surfaces of a still by using sponge liner; 2) to find the optimum thickness of sponge liner. Two single-slope solar stills are ...

  • Assessing Frost Damage in Compacted Clay Liners

    Methods used to assess frost damage (here defined as a large increase in hydraulic conductivity) in compacted clay liners are reviewed and evaluated using data collected from two test pads that were instrumented and then exposed to winter weather. The methods include comparisons of measurements of either water content and dry unit weight or hydraulic conductivity made before and after winter ...

  • Electrical Leak Location Arc Tester to Revolutionize Liner Quality

    New equipment has been developed that behaves like a spark tester, but doesn’t have to be performed on conductive-backed geomembrane.  It has the same requirements as the water puddle and water lance methods in terms of a conductive layer underlying the geomembrane, including soil.  It is not a spark tester, which is used exclusively on conductive-backed geomembrane; yet, it ...

  • Chemical Mass Transport Measurements to Determine Flexible Membrane Liner Lifetime

    The prediction of the service life of flexible membrane liners (FMLs) when exposed to chemicals has usually been by way of testing for physical or mechanical property changes after periodic exposure times. This paper presents an alternate approach by evaluating the chemical properties via five different mass transport related measurements of the exposed FML. These tests are water vapor ...

  • Trouble Shooting for Trenchless Liner Installation During Sewer Line Rehabilitation

    ABSTRACTLining is being used by the utility industry as a cost effective solution to rehabilitate utility lines. Many types of liners, such as, cured-in-place-pipe (CIPP), fold and form PVC, deformed & reformed HDPE, etc., are being used to restore structural integrity of deteriorated pipes and to reduce inflow/infiltration. Most of the lining installation is carried out without any problem, ...

  • Pollution level detection in dump clay liners by hyperspectral imaging

    Landfill is the most common and cost–effective method of waste disposal, with collection and transportation accounting for 75% of the total cost. A key point in waste disposal is the picking up and the drainage of percolation fluids to limit the risk of groundwater contamination. Aim of this study was to evaluate the possibility to develop fast and reliable methods to perform an in situ ...

  • 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 ...

  • 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 ...
