Investigation of Cleaning Efficiency of Biological Air-Treatment Device with Activated Charge of Different Origin
Journal Title: Journal of Environmental Engineering and Landscape Management - Year 2008, Vol 16, Issue 3
Abstract
In order to carry out an experimental investigation a biological air-treatment device was used, namely, a biofilter with a charge of a different origin composed of zeolite, foam and wood chips. When mixing foam and zeolite together with wood chips for air treatment from volatile organic compounds, not only a biological but also adsorptive air-treatment method is used. Using complex treatment technologies the device efficiency and the charge service period are improved. The investigation has shown that microorganisms, being predominant in the bio-treatment process, can breed in charges of on inor-ganic origin made of natural zeolite and foam. While cultivating spontaneous microorganism associations in the charge, biofilter treatment efficiency was determined to be dependent on the sort of the supplied pollutant, concentration and fil-tration period. The charge filtration function was most efficient at a velocity of 0,1 m/s when the device was supplied with acetone-polluted air. Cleaning air from acetone, when the original concentration of the pollutant was 103 mg/m[sup]3[/sup], the filter treatment efficiency reached 95%. When the concentration of pollutants supplied into the biofilter is reduced and the filtration period is increased, the device treatment efficiency increases as well.
