  • 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 ...


  • Particles Matter

    We all can recall our mothers telling us as children to go outside and get some fresh air.  Who would have known just how important this statement was and is today?  Air pollution affects the entire planet. You can't escape it anywhere not even inside your home or office. According to the United States Environmental Protection Agency (EPA), indoor air can be up to ten times more ...

  • Office Printers Emit Ultra fine particle pollution

    We’ve heard quite a bit about particulate matter PM10s and PM2.5s as components of air pollution that we are exposed to on a daily basis. Recent research papers are highlighting the dangers of ultra fine particles (UFPs), which have a diameter of less than 0.1 micrometres (or 100 nanometres). By contrast, the diameters of particulate pollution from PM10s and ...

  • 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, ...

  • Oxygen Monitor for FOUPs in Semiconductors and Cleanrooms

    Over time, the contamination control requirements in the semiconductor industry have become more stringent. Employees now must spend more time adhering to cleaning protocols to preserve the sanitary nature of the environment and comply with regulations. The front-end unified pod (or FOUP) began appearing in semiconductors in the 1990s, serving as a transportation box to safely and ...

  • Media expansion monitoring improves filtration

    In municipal surface water treatment plants, optimum filter performance is a crucial component. Filtration is the primary treatment process at water treatment plants, and backwashing is the primary means to keep filters functioning properly to produce safe drinking water for the public. Since 2000, Entech Design, Inc. has used underwater acoustic sensing technology to monitor filter media ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Radionuclides in wastewater treatment plants: monitoring of Sicilian plants

    Three Sicilian wastewater treatment plants were monitored to assess the occurrence and the behaviour of radionuclides. Two sampling campaigns (screening and long-term) were carried out during which liquid and solid samples have been analysed. It was found that 131I mostly occurred in the samples analysed during the screening campaign (43% of the analysed samples contained 131I). ...

  • Status of black carbon monitoring in ambient air in Europe

    Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...

  • Air Separation Plants and the Use of Oxygen Monitors

    Air separation plants are critical for many different industries, from clean energy to manufacturing. Nowadays, cryogenic is the most common type of distillation used to separate air into its component gases - nitrogen, oxygen, and inert gases including helium and argon. If your industry relies on air separation for product development or manufacturing, then knowing how the process works is ...

  • Reliable silica monitoring supports power station efficiency

    West Burton B CCGT is a Combined Cycle Gas Turbine power station near Nottingham in the UK. It has three open-cycle gas turbines capable of generating enough electricity for approximately 1.5 million UK homes. In common with all combustion based power stations, the CCGT has a requirement to monitor silica levels in the Plant’s water and steam processes. Sean Todd, the Plant’s Control ...

  • A novel acoustic imaging tool for monitoring the state of rapid sand filters

    A new technology based on acoustic waves is developed to monitor the state of sand filters used in drinking water treatment. Changes in the sand filter, due to the removal of suspended particles from the water and their accumulation in the pores, result in an increase of the bulk density and acoustic speed of the granular material. Consequently, the reflected acoustic response changes as the ...

  • Black carbon emissions of individual cars measured under real conditions

    Measurements of individual vehicle emissions are usually made in laboratory tests. In this study, researchers followed cars driving in real conditions to measure emissions of air pollutants, including black carbon and nitrogen oxides. The study shows that diesel cars contribute disproportionately to air pollution, and highlights the value of on-road measurements. Vehicle traffic is a major source ...

  • Insect cell-based impedance biosensors: a novel technique to monitor the toxicity of environmental pollutants

    Abstract Cell biosensors are currently emerging as novel, sensitive techniques to monitor the toxicity of environmental pollutants. Here, we have developed electric cell-substrate impedance sensing (ECIS) for on-line monitoring of the behavior of insect cells. Cells were cultured on a microarray of eight small gold electrodes, deposited on the bottom of tissue culture wells. Upon inoculation, ...
