  • Fibre optic sensors as a non–destructive tool for structural monitoring

    Structural monitoring is a diagnostic tool for detection of defects/damages and for scheduling maintenance operations. It is essential to determine the safety of the structures by Non–Destructive Testing (NDT) for evaluation of strength/integrity. This assessment is required for the repair, rehabilitation and life extension of the structure. Fibre Optic Sensors (FOS) are attractive sensing ...

  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • Non-destructive analysis of concrete for corrosion studies using nuclear technique

    Chloride-induced reinforcement corrosion is the principal cause of deterioration of concrete structures in the Arabian Gulf and the world over. Preventive measures against corrosion require maintaining the chloride and sulphate concentration in concrete below the threshold limits specified by the standards. This requires monitoring the chloride and sulphate concentration in concrete, and a ...

  • Oil Sampling Best Practices

    Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These ...

  • Dust monitoring

    Generally, two different approaches are used to measure the amount of dust deposited on a surface; Determination of the soiling of a surface, by a change in its properties; Determination of the quantity of dust deposited, by weight. WHAT IS DUST? Dust is a generic term used to describe fine particles that are suspended in the atmosphere. Dust comes from a wide variety of sources, including soil, ...

  • Digital Change Detection Using Remotely Sensed Data for Monitoring Green Space Destruction in Tabriz

    Being very dynamic, natural and artificial land features are changing somewhat rapidly in over lifetime. It is important that such changes be inventoried accurately so that the physical and human processes at work can be more fully understood. Change detection is a technique used in remote sensing to determine the changes in a particular object of study between two or more time ...

  • NOx in Non-Utility Industries - Part II - Control options and monitoring methodology

     This the second in a two-part series. Part I, which appeared in our June 2001 issue focuses on air emission origins of nitrogen oxides (NOx) in non-utility industries. Choice of the NOx control technology is dependent on many factors, including regulatory requirements, technical feasibility, cost and public perception. Figure 1, compiled based on publications [1-5], presents a summary of ...


  • Monitoring Oil in Cooling Water

    The Situation A municipal power plant in the southern United States operates more than 10 stationary power plant engines capable of producing 52 megawatts of electric power. The plant is part of a larger statewide power grid system. Within the grid, the municipality brokers the purchase or sale of power hourly, based on the needs of municipality and the market rate for power on the grid ...

  • Monitoring and Treatment of Selected Nanoparticles

    With their increasing use, nanoparticles will become concentrated in urban effluents in the future. Both adequate monitoring methods and water treatment technologies will be necessary to assess and avoid consumer exposure. This paper reports results in these two challenging areas for both organic and inorganic nanoparticles. Treatment experiments indicate that lamellar settling is better adapted ...

  • Plant area monitoring at Krško

    Post-Fukushima upgrades at Krško in Slovenia (www.nek.si) are being implemented in accordance with the requirements of the national regulator and the plant owners. The first phase, including a passive containment vent filtering system and hydrogen recombiners, a new emergency diesel generator, and a protected store of mobile emergency equipment, is already completed. The next phase in ...

  • Case study - Destruction of inert process emissions

    Many chemical companies use batch reactors to make their products.  These reactors typically have vents which are opened and closed during emptying, filling, mixing, heating or cooling and other steps of the production process.  The gases coming from these vents must be controlled under most government regulations.  Generally speaking, the emissions produced are inert (little or no ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Oil on Water Monitoring

    Northern Ireland Water operate a number of potable water plants around Lough Erne and the River Derg, these waterways are extremely popular with tourists and are used for pleasure crafts of various sizes, from jetskis to fully fitted 6 berth cruisers. These watercraft create an ongoing risk of floating oil from poorly maintained engines, as the watercraft have access to within 10 metres of the ...

  • Municipal sewer remote monitoring

    Sewers are critical heavy duty infrastructure components requiring costly maintenance. Many municipalities suffer from ageing pipelines that pose higher chances of failure. Sewer leak or overflow results in high cost as a result of civil reimbursement and due to inflected illness. Moreover Civilian frustration that results form the overflow is often targeted towards the municipality. Overflow can ...

  • Monitoring Hydroelectric Dam Sumps

There are numerous sources for oil spillage: The hydroelectric turbines are lubricated by standard lubrication oils; The very large water control valves are normally ...

  • Staying Safe with Environmental Monitoring

    Geotechnical Instrumentation involves administering the earth and environment and it is hence that designers have made different frameworks to make the occupation simpler. These frameworks grab thousands upon much information that it orders and illuminates so they can concoct evidence. The places where it is necessary are the pollution chance appraisal, trends in time and space; anticipatory ...

  • Estimation and monitoring non-point source pollutant loads: an object-oriented hydro-information approach

    Numerous hydrologic/water quality models of run-off and soil erosion have been coupled to Geographical Information System (GIS) to determine Non-Point Source (NPS) pollutants from watersheds. Hydrology and water-resource engineering rely on observations of environmental conditions and the accuracy of environmental data. This paper focuses on estimation and monitoring of NPS pollutant loads based ...

  • In Situ Rheological Monitoring of Viscous Non-Newtonian Fluids using a Helical Ribbon Agitator

    Mechanically degraded food fluids were modelled as Power law fluids in a pilot scale (42 l) helical ribbon agitation vessel. Effective rheological representative flow curves determined from speed/torque data proved comparable to off-line laboratory rheometer measured data. Modelling effective viscosity as a Power law function gave effective consistency coefficient Keff which correlated strongly ...
