  • Water Vapor Interference in the UV Absorption Measurement of Atmospheric Ozone

    In this thesis work, a significant and sometimes large water vapor interference inherent to many and possibly all UV-based, commercially available ozone monitors was positively identified for the first time.  Depending upon the instrument's recent atmospheric history and calibration method, zone monitors can give erroneous results both immediately and hours later, and as a consequence possibly ...

  • Monitoring fuels in Stormwater - Case study

    The Situation A major pipeline company has large storage tank farms throughout the Western States. The pipeline company transports, stores, blends additives, and distributes gasoline, diesel, and jet fuel to retail service stations and airports. Due to the quantity and movement of fuel at these facilities, there is always the potential for fuel spills. These facilities prevent out of ...

  • Unmanned remote and wireless CDM monitoring case study

    Remote and wireless monitoring technology to meet CDM requirements is in its infancy in Europe. Carbon trading is driving it globally, especially in North and South America. That experience and technology is now finding a demand in Europe and Asia in landfill, biogas from food and animal waste in digesters and water treatment sludge digestion. Methane recovery from landfill and anaerobic ...

  • NASA campaign KORUS-AQ: IONICON PTR-TOF to monitor VOCs above Korea

    Team of the University of Innsbruck and an IONICON PTR-TOFMS aboard NASA research aircraft An international team coordinated by NASA has recently investigated air pollution over the Korean peninsula. Two of IONICON’s PTR-TOFMS instruments were used to monitor volatile organic compounds (VOCs) in real-time aboard NASA’s DC-8 Flying Laboratory. The data gathered by scientists ...

  • 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 ...

  • Case study : VOC analysis in ambient air by FID dectection - Complete system airmOzone

    Ozone concentration has been multiplied by 5 in the last century in the middle latitudes of the northern hemisphere from 10 PPB in 1874 to approximately 50 PPB today. This is an increase of 1.6% per year; the trend is probably higher (2.4% a year) over the last decades. (Chapter 1 of the International Geosphere-Biosphere Program - World Climate Research Program) In order to stop this global ...

  • Performance-Based Measurement Systems

    Many of the Environmental Protection Agency's (EPA's) methods used to monitor air, water and soil for environmental contaminants prescribe step-by-step details on how the chemical analysis must be conducted and prohibit any deviations or variations. The EPA has recognized that monitoring equipment and technology have improved tremendously over the last few years; that environmental media do not ...

  • Mobile Stationary Source Emissions Testing, Coming to a Facility Near You?

    Last week, Antea Group had the unique opportunity to perform a RATA (relative accuracy test audit) of the emissions from a thermal oxidizer at an ethanol production facility located in Minnesota using a state-of-the-art mobile testing laboratory. During this RATA audit, actual stack emissions levels (including NOx, SOx, CO2, CO, O2, flow rate, temperature, velocity and pressure) from the ...

  • The Light at the End of the Tunnel - How to Successfully Operate a UV Disinfection System

    ABSTRACTOver the past ten years, ultraviolet (UV) technology has become a commonly applied method of disinfecting of wastewater effluent. UV disinfection involves passing wastewater effluent through a confined chamber with rows of underwater lamps emitting UV energy. Viruses and bacteria become inactivated upon exposure to dosages of UV energy, thereby disinfecting the wastewater. The UV system ...

  • The Benefits Of UV Disinfection In The Pharmaceutical Industry

    The quality standards required for purified water in the production of pharmaceuticals have never been stricter, with manufacturers having to conform to an ever increasing number of international standards. Craig Howarth, Managing Director of Hanovia Limited, introduces a number of interesting new developments in UV technology for disinfection and dechlorination. ...

  • Real-time TOC tightens effluent control at Greencore

    A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process. As a result the plant is better able to quickly respond to changes in the influent. Greencore Foods is a leading player in the food ...


  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • 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 ...

  • Emerging Trends In UV Disinfection For Water Treatment

    Introduction The UV disinfection industry has experienced tremendous growth over the last 20 years.  The development of new UV technologies over this period has been a perfect example of an industry investing to meet market demand – in this case demand for an effective, low cost, and environmentally friendly disinfection technology.  The acceptance of UV disinfection at water plants ...

  • Using FTIR spectroscopy to measure hydrocarbon pollution in water

    According to the World Health Organization (WHO) and UNICEF’s 2015 Progress on Sanitation and Drinking Water report almost 700 million people around the world don’t have access to clean drinking water [1]. Poor water quality is beginning to return to the developed world too. The strain of population growth, intensified agricultural practices and continued industrial expansion have are ...
