Abstract
- Air cleaning efficiency tests on placing material load into the lavsan biofilter were carried out. Testing included butanol vapour-contaminated air stream pulled during the boot. The studies were conducted by the Department of Environmental Protection at VGTU that developed a biofilter - an experimental biological air cleaning device. Measurements were done using 60 lmin and 90 lmin air volume aspirators under the initial pollutant concentration making 180,305, 350,440 and 545 mg/m³. Before measuring the concentrations of butanol lavsan cartridge, loading was periodically irrigated with nutrient-rich solution. In order to evaluate the influence of microorganisms on genus Pseudomonas, cleaning efficiency tests were repeated - Boot was moistened with water only, which allowed measuring butanol vapour concentrations after the cartridge. At the concentration of 180±9 mg/m³, efficiency reached 41% at a speed of 0,07 m/s and 46 % at a speed of 0,10 m/s. Measuring the performance of the initial concentration of 545±67 mg/m³, efficiency was 54% at 0,07 m/s and 53 % at 0,10 m/s respectively. [ABSTRACT FROM AUTHOR]
