Cleaning of H2S from polluted air using peat biofilter
Every year about 64 thousand tons of polluted air is being released to the ambient air. More than 30% of this pollution consists of toxic sulfur compounds. The properties of biological air cleaning technology – biofoltration with peat media – has been discussed in the article. Research was performed...

Santrauka
Šiais laikais tiek išsivysčiusiose, tiek ir besivystančiose šalyse egzistuojanti problema yra greitai besiplečiančių pramonės ir energetikos sektorių į aplinkos orą išmetama cheminių junginių tarša (apie 64 tūkst. tonų per metus), iš kurių apie 30 % sudaro žmogui nuodingi ir aplinkai neigiamą poveikį darantys sieros junginiai.
