  • What classifies as water pollution and why is it an issue?

    The UN declared 2005-2015 as the International Decade for Action ‘Water for Life’. Yet each day thousands of people still die as a result of contaminated water. This does not even take into account the millions of organisms that perish every year thank to polluted water sources. Water pollution is a huge issue that is made more so by the fact that unfortunately, water is ...

  • 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 ...

  • Monitoring of nitrogen dioxide in and around an Oman liquid natural gas plant using passive diffusion tubes: exposure and ISCST model study

    Recognising that nitrogen dioxide (NO2) may be the primary air contaminant released from an Oman liquid natural gas (LNG) plant, this study has been designed with emphasis on this pollutant. The dispersion of NO2 was examined and compared with measured data during the period from 23 February to 1 April 2001. The observed concentrations were obtained by using NO2 ...

  • 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 ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • How Accurate is Your Monitor?

    When you consider the many regulations and guidelines that health and safety officers and first responders are faced with, it is amazing they maintain the ability to detect such a wide variety of hazardous pollutants and toxic agents.  There is no lack of regulations governing how to monitor chemical compounds, and the list grows longer all the time.  New standards for portable gas ...

  • Monitoring And Analysis of Landfill Gases

    CoGDEM is the trade association representing manufacturers and service providers who are active in the field of gas detection instrumentation and environmental monitoring apparatus. Crowcon Detection Instruments Ltd was one of the founding members of CoGDEM, and in this article their Product Manager of Fixed Systems, Andy Avenell, gives an update on Landfill Gas. Landfill is by far the most ...

  • The effect of quench on Quantitating Alpha Radionuclides by Liquid Scintillation Counting

    Detecting and quantitating alpha emitting radionuclides are routine tasks in nuclear energy and environmental monitoring. For this purpose, liquid scintillation counting (LSC) is an excellent method because alphas are counted with nearly 100% counting efficiency with low backgrounds, even with severe quenching. Quenching agents such as inorganic acids, organic acids, and extractive scintillators ...

  • Thermal deoilers - Thermal deoiling replaces liquid based degreasing

    The Problem A major Automotive company was mandated to have an alternate technology for degreasing evaporator fins. They had, until recently, been deoiling metal parts in a conveyorized solvent based vapor degreasing line, but the state environmental agency mandated that the line be shut down on a certain date due to the excessive water and air pollution it generated. The company had ...

  • Monitoring flammable gas in boiler houses

    The most common fuels in use for space and water heating are Oil, Natural Gas and Liquid Petroleum Gas (LPG). By far the most popular, clean and cost effective solutions are utilising Natural Gas or LPG. The traditional safety measure derived from the time of oil fired boiler houses is the use of a fusible link placed above the each boiler. The fusible link is intended to melt if it becomes ...

  • Surfactant-assisted oil-in-water monitoring

    A variety of common surfactants have been used to reduce fouling and enhance the performance of fluorescence-based oil-in-water monitors. Among the most effective are the alcohol ethoxylates with HLB values close to 12. Examples are SurfonicTM L24-9 (Hunstman, USA, HLB 13) and TergitolTM 15-S-7 (HLB 12.1). These surfactants readily convert heterogeneous oil/water mixtures into homogeneous, ...
