OPSIS is contributing to improved air quality in Lund, Sweden. An article published by Swedish newspaper Sydsvenskan gives a glimpse into the improvements that has been made over the years with OPSIS systems as a part of the progress. https://www.sydsvenskan.se/lund/lundaluften-har-blivit-battre-har-ar-forklaringen/

Ny rapport visar att Lund redan klarar EU:s strängare gränsvärden för luftkvalitet.

☁️Application of the Month – November: Gas Monitoring in Glass Manufacturing☁️

Glass production involves the mixing of silica and other oxides, followed by heating, forming, and cooling, all under well-controlled conditions. By nature, the production process is associated with high temperatures and high dust levels.

From a gas monitoring perspective, a glass manufacturing industry is similar to many other heat production facilities such as power plants. It is typically of interest to measure the concentrations of the “traditional” CEM gases such as NO, NO2, SO2, CO2 and O2, together with pressure, temperature, and sometimes dust and flow. NH3 can be measured to control urea injection and monitor SCR efficiency. There can also be needs for measurement of concentrations of “exotic” types of gases such as HF.

Several types of OPSIS CEM systems are suitable for use within the glass manufacturing industry. Learn more on our application page https://www.opsis.se/en/applications/emissions-monitoring-process-control/glass-manufacturing-industries/

The EU’s new Air Quality Directive 2024/2881 comes into force by the end of 2026. It contains many new provisions compared to the directives it replaces. Among other things, it introduces new and stricter air quality standards that must be met by 2030. However, to achieve this, work under the new directive will need to begin as early as the start of 2027. Read on in the link below for an overview of the changes and what needs to be done in the near future.

☁️Application of the Month – October: Data Handling☁️

How can air quality monitoring data be handled reliably and securely, while keeping data collection, storage, and access straightforward?

OPSIS Data Services is a subscription-based service for collecting, storing, and managing air quality monitoring data. Data is stored on OPSIS-hosted servers, with information security managed in accordance with ISO/IEC 27001.

The service offers flexible options for accessing and presenting data, along with automatic data validation, alarm functions, calculations, and data export. Combined with our WT256 data logger, it provides a complete chain from measurement to finished data.

Within the European Union, the waste incineration BAT conclusions (WI-BATC) calls for sampling of PCDDs, PCDFs, dioxin-line PCBs, and states maximum concentrations (TEQ weights per volume) obtained either during short-term or long-term sampling. But what does it mean? We explain it in our blog post linked below.

Why are we monitoring ozone?

Ozone can protect life on earth from harmful ultraviolet radiation from the sun, but it is also a harmful air pollutant that can affect human health, crops, and forests. As ozone can be transported over long distances, elevated concentrations may occur even far from apparent sources of air pollution. Monitoring ozone therefore helps us understand air quality, assess levels against air-quality targets, and provide timely information when concentrations become a concern. For more information about ozone monitoring in the gas monitoring industry, read our blog post 'Keep an Eye on Ozone" in the link below.
