Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

Measurement of moisture in HBr

Introduction Moisture in corrosive gases will accelerate the rate of metal corrosion in gas supply systems which, in turn, can lead to their premature failure. For this reason, it is important to monitor moisture levels in these gases. FTIR is an effective way to monitor for moisture in these corrosive gases. In order to determine low levels of moisture in corrosive gases, it is ...
