Pollutants in Emissions to Air – What’s in the Smoke?
Speaking of industrial emissions to air, it is often a matter of emissions resulting from combustion processes. The main components of the emissions are nitrogen and some excess oxygen originating from the incoming air being fed to the combustion process, as well as water and carbon dioxide (CO2) being the primary results of the combustion reactions. The concentrations are at percentage levels. ...

Selenium recovery from kiln powder of cement manufacturing by chemical leaching and bioreduction
A novel process by using chemical leaching followed by bacterial reductive precipitation was proposed for selenium recovery from kiln powder as a byproduct of cement manufacturing. The kiln powder at a slurry concentration of 10 w/v% with 0.25 M Na2CO3 at 28°C produced wastewater containing about 30 mg-Se/L selenium. The wastewater was diluted four-fold and adjusted to pH 8.0 as ...
