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.
Sterlitech to Provide Larger Scale Membrane Skids for Research and Industry Customers
These pilot skid systems are specifically designed for pilot testing of spiral wound membrane filters or small scale filtration processes. They offer more than 200 times the filtration surface available in standard bench-top filtration systems, allowing users to increase throughput and obtain results that translate for scale-up. Digital skids enable hands-free monitoring of process parameters and eliminate the need to manually record data. Built in benefits include: Pre-assembled and plug-in ready Digital or...
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...
