Through partnership with IDAEA-CSIC two AQMesh pods were co-located with a reference station and scaled locally in Barcelona (ref. Advanced user mode), providing R2 of 0.97 for NO and 0.89 for NO2. One pod was then moved to a second reference point within the city to establish repeatability of results using the scaling factors derived from the first reference. This resulted in a correlation of 0.98 for NO, and 0.86 for NO2. This trial shows that a high degree of air quality monitoring accuracy can be achieved through local scaling and this accuracy is maintained when AQMesh is then used to monitor independently in new locations.
Yet another `Real world´ test of Sialex®Ring`s ability to remove and control `Boiler Scale´
A particularly difficult "test" was selected. It should be said that in quite a few cases Sialex®Ring is selected when all else fails. However, by demonstrating the products abilities, more companies are exposed to the products capabilities. THe test in this case; a boiler using locally sourced , untreated water from a "hard" water area (hardness expressed as Caco3 = 1,130mg/l.) The boiler already exhibited signs of severe "Scale" build-up before testing began. "Feed water" water hardness was monitored and...
Landfill Methane Emission Monitoring
Methane (CH4) plays a critical role in the radiation balance and chemistry of the atmosphere. The major anthropogenic sources are anaerobic production from landfills, ruminant animals and their waste, release from the mining and use of fossil fuel, burning of biomass, etc.. On average, over the global scale, landfill methane emissions contribute between 10-19% of the anthropogenic methane burden into the atmosphere CH4 is a potent greenhouse gas – about 25 times stronger than CO and outgases from reservoirs...
Site Remediation - Emissions Boundary Monitoring
The remediation of contaminated land sites can prove to be a challenging undertaking. There is considerable risk of chemical exposure to both the onsite workforce and to surrounding communities. To offsite receptors, the remediation process itself can become a significant route of exposure, with the excavation and uncovering of otherwise trapped contaminants resulting in potential volatilisation and aerosolisation of organic and inorganic toxic compounds. As such, it is often necessary to undertake monitoring...
Landfill and Biogas gas monitoring
Landfill and biogas provide a source of readily available and renewable energy. However, as a source of energy care has to be taken to understand and quantify impurities in the raw gas that can have an effect on either the amount of energy products, or contaminants that can foul the energy generators (siloxanes). ETG can provide analysis solutions to qualify and quantify these impurities. Gas engines from landfill have a high proportion of formaldehyde emissions, and just as our analyser can provide a solution...
AQMesh: a new option for flexible air quality monitoring
AQMesh has an impressive collection of global users and performance results measuring ambient air quality in applications ranging from traffic planning and urban hotspots to industrial fence line monitoring, building ventilation management, or environmental lobbying. This pole-mounted unit comes with an independent power supply and communications, so offering the possibility of measuring air quality exactly where it is required. Readings are accessed securely online at intervals as short as 5 minutes and can...
