carbon dioxide (CO2)

The paper shows the possibility of using chlorophyll-synthesizing microalgae of Chlorella Vulgaris to purify biogas from carbon dioxide (CO2), hydrogen sulfide (H2S) and ammonia (NH3). Experimental dependences of the dynamics of CO2 uptake by microalgae under the action of H2S inhibitor and NH3 activator are presented. A mathematical description of the growth of biomass of microalgae Chlorella Vulgaris depending on the concentration of hydrogen sulfide and ammonia was obtained.

The paper focuses on the natural ventilation research of space through windows. The various ventilation strategies were examined in relation to the number of open windows and ventilation geometry ergo air flow distribution. The numbers of chosen air flow distributions in space are 2. The first air distribution flow presents a simple ventilation distribution with one open window and the second is cross ventilation by 2 windows on opposite sides of the building envelope.
