The effect of pressure on removal of carbon monoxide in biofilter

Abstract

Solubility of carbon monoxide in water is very important for its biological oxidation or removal process of gaseous pollutants. Present research shows the effect of pressure on solubility of carbon monoxide in liquid phase and its removal process by a biofilter. The results are considered as laboratory research on carbon monoxide elimination. In this method a pressurized trickle-bed biofilter was used to increase pressure in the reactor. The biofilter was filled with Leca-stones and inoculated with microorganisms. When the system's pressure is increased, the solubility of carbon monoxide will be increased, respectively, and it causes a better reaction of the microorganisms for removing of gaseous pollutants. The efficiency was improved significantly by increasing the pressure in the reactor.

Involvement of the Heme Oxygenase System in the Development of Preeclampsia and as a Possible Therapeutic Target

“…Though the authors measure nicotine levels in the CSE media, they do not measure CO. It is known that the solubility of CO in water is very low [82], and we have measured the rapid reduction of CO in media using gas–solid chromatography (Venditti CC & Smith GN, Unpublished Data.). If CO is the agent in cigarette smoke leading to a decrease in placental apoptosis, its absence in CSE media would result in differing results.…”
