  • 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 ...

  • EPA Regulations Raise the Bar for Industrial Air Quality Testing

    Far-reaching environmental legislation continues to change the way Americans live, work, and run their businesses. For the past ...

  • Equivalence of Air and Water Permeability Tests in Evaluating Engineering Fabrics

    Permeability characteristics of civil engineering filter fabrics are currently evaluated by three types of tests: air permeability and falling-head and constant-head water permeability. Test procedures for the falling-head and constant-head water permeability tests are discussed, and results from these tests are correlated to air permeability results for filter fabrics. Several commercially ...

  • Purpose of Air and Surface Mold Sampling or Testing during Assessment

    As part of determining whether an indoor environment is contaminated with excessive amounts of mold and requires remediation, Indoor Environmental Technologies (IET) routinely performs air and surface mold sampling or testing. While there are many types of sampling, IET uses two of them the most: Air sampling using a “spore trap” sampler. Considerable information ...

  • Ultrasonic Testing For Non Destructive Testing

    Ultrasonic Testing or UT as its known has programs in a wide range of sectors, from aerospace, automobile, to substance, oil, large storage space, and power creation and overseas. UT is aspect of a selection of techniques known as NDT (Non Destructive Testing) methods. Their objective in industry is to allow the examination of parts and equipment ...

  • Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

    There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

  • AIRE-O2® Aerators tests number one in three critical areas - Case Study

    Problem In 1986, this southern USA fine paper mill developed problems on start-up from a Christmas shut-down, requiring quick action to add efficient aeration to its 38 MGD (143,830 m 3) flow. Poor winter treatment, channeling throught the system, and high solids had also been problems. Since the company was committed to preserving the environment, it searched for the best aerators to ...

  • Air Products Opens LNG Equipment Test Facility, Expands LNG Manufacturing Plant

    Air Products, the world’s leader in LNG technology and equipment, recently held a dual celebration event at its Port Manatee, Florida LNG Manufacturing Facility. Participants took part in the ribbon-cutting for a new LNG equipment test facility (ETF) and a groundbreaking for a facility manufacturing expansion project at the site. The location ...

  • Air Volume Change Measurement in Unsaturated Soil Testing Using a Digital Pressure-Volume Controller

    One of the challenges associated with the testing of unsaturated soils is the measurement of air volume change induced by stress changes. This paper reports the results of an evaluation of a digital pressure-volume controller as an air volume change indicator. Effects of temperature, confined volume, and precompression of the measurement medium on the p-V characteristics and the device response ...

  • Use of Air Bag System for Instrumentation of Lateral Load Tests on Previously Installed Pipe Piles

    A simple and inexpensive air bag system for allowing measurement of the deflected shape of laterally loaded piles has been developed. The air bag system may be used for hollow piles that have already been installed. The system includes an inclinometer casing that is held against the inner wall of the pile by an inflated air bag. Tests on small- and large-diameter steel pipe piles at two different ...

  • Proposed Standard Test Method for Measurement of Pneumatic Permeability of Partially Saturated Porous Materials by Flowing Air

    This proposed standard describes a laboratory test method for the measurement of the coefficient of permeability for airflow (pneumatic permeability) through porous media (e.g., soils) partially saturated with water. Control and measurement of the airflow is effected at the inlet of the specimen. The permeameter cell is fitted with dual transfer lines that isolate the specimen pressure drop from ...

  • US EPA airmOzone TESTS

    The US EPA leads Photochemical Assessment Monitoring Stations programs (PAMS) for more than 15 years and many equipments used at PAMS sites are old and need to be replaced. That is why US EPA has conducted a material review of fully automatic GC units able to by analyze the 56 VOC ozone precursors of the PAMS list. They planned to perform an evaluation in two steps : - Laboratory evaluation of ...

  • Vibration testing of fuel probes

    Aerial Refuelling The American Bell-Boeing V-22 Osprey is a multimission, military, tilt rotor aircraft with both a vertical and short takeoff and landing capability. It combines the functionality of a conventional helicopter with the high-speed cruise performance of a long-range turboprop aircraft. But even though it is long-range, some missions require in-flight refuelling. The V-22 Osprey can ...

  • Legionnaires is an Air Quality Risk

    The recent Bronx, NY outbreak of Legionnaires infections is a grim reminder of the deadliness of this strain of pneumonia. Like many of the outbreaks, cooling towers caused this one. Twenty have been identified but the search is still going on. Over 120 people were infected and 12 have died. Tragically it affects the most vulnerable people–people with one or more immune system deficiencies. ...
