  • Analysis of gamma ray incoherent scattering for non-destructive testing

    An approach for the analysis of gamma ray incoherent scattering on free and binding electrons is presented for Non-destructive Testing (NDT). The method is based on computational simulation and backscattering gamma ray measurements for carbon steel walls. The results of thickness measurements for steel walls are described by the theory of the energy transfer model.Keywords: gamma ray incoherent ...

  • 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 ...

  • 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 ...

  • Case Study: Odor Abatement Solutions

    Odor issues related to industrial processes are not uncommon.  An odor is caused by one or more volatilized organic compounds (VOCs) that humans can perceive by the sense of smell.  The challenge is that “odor is subjective, and what is sweet to some, can be a nuisance to others.   In most cases the ...

  • Daily measures of microbes and human health at a non-point source marine beach

    Studies evaluating the relationship between microbes and human health at non-point source beaches are necessary for establishing criteria which would protect public health while minimizing economic burdens. The objective of this study was to evaluate water quality and daily cumulative health effects (gastrointestinal, skin, and respiratory illnesses) for bathers at a non-point source subtropical ...

  • BOS 100 bench study: destruction of TCE

    The TCE destruction chart shows a 99.95% reduction in the presence of TCE after 2 hours of contact with Trap & Treat® BOS 100®, and 99.99% reduction in tie presence of TCE after 6 days. (The numbers shown are in ppb.) The graph on the right shows the actual destruction of TCE by measuring the chloride atoms released as TCE is broken down. The graph shows that over 50% of the original ...

  • Deep Well Measurement

    Pulsar's superior echo processing was proven once again in this difficult very deep Welsh wet well application featuring a 23m 'shot' that needed to follow the level between the heads of two submersible pumps. The reliability and versatility of the advanced echo processing technology in Pulsars non-contact ultrasonic range has been utilised at the SwanseaWasteWater TreatmentWorks, in a 23m deep ...

  • Non-contacting Ultrasonic Pumping Station Flow Measurement Saves Money for Dwr Cymru Welsh Water

    Dwr Cymru Welsh Water has benefitted from the unique 'Pumped Volume' feature built into Pulsar's Quantum 2 Pump Station Controller; identifying a flow problem within a pumping station network without the need for expensive Magflow meters. Once the issue was resolved, pumped volume through one of the stations was reduced by 88% , ...

  • Avoiding the costs of non-compliance

    Focused EHS management both saves money, enhances an operation’s chances of avoiding costly claims of liability and/or enforcemcnt scrutiny, and enables manufacturers afflrmatively to promote their commitment to sustainability and stewardship, thus increasing their prominence in the eyes of their employees and third parties. LIABILITY is COSTLYAsk anyone who has become embroiled in any form of ...

  • Bed Level Measurement

    Numerous studies and papers have been devoted to the subject of thickener design and operation to achieve specified throughput and discharge densities. Mathematical models have been developed that present methods for sizing thickeners and predicting performance under varying process conditions. The compression effect of deeper beds on dewatering performance is a recognized phenomenon. This is one ...

  • Automating CFD for non-experts

    ABSTRACT The focus of the paper is on demonstrating how it is possible to automate complex CFD simulations using scripting language around and within the structure of the CFD command files. To illustrate this, the concept of an atmospheric pollution case is used and, more specifically, that of a water treatment plant. The code that is used is CFX-5 with PERL as a scripting ‘language’.The ...

  • The number of 'non-captives' as an indicator of the quality of public transport supply: an alternative quality measure in the context of mobility-management

    Since the mid 90's, mobility management measures have been used to influence the choice of transportation means in favour of public transport. However they have been rarely applied in the context of leisure traffic. The scope of this study is to determine a conceptual framework for mobility management measures regarding the field of recreational facilities. The article uses the quality perception ...
