Application-Economical Investigation of various Bioreactors for Removal of Air Pollutants

In recent years, due to increase of industries activities and industrial technologies, air pollution has a significant increase. As you know, daily growth of industrial factories next to cities, along with other air pollutant agents such as vehicles, led to increase of air pollutants emissions. By considering this condition in issue of air pollution due to industrial activities, it is reasonable to take fundamental decisions for air purification by selecting appropriate and economical methods and prevent the entry of pollutants into the air as possible. One of air purification tools in the field of industry and other sections such as treatment of emissions from composting units and wastewater treatment plants, are biofilters. Basically biofelters are used for treatment of gases containing odor compounds and other volatile organic compounds. The aim of this study is assessment and investigation of biofilters as one of air purification method compared with other methods, in order to apply more useful and economical option among so many different tools. In this research, biofilters were compared with adsorption and catalytic oxidation methods in terms of application and economical and initial investment costs was determined, and based on the results of the study, the advantages of biofilters relative to other methods was determined. Also, biofilters were investigated in terms of improvement of efficiency and applicability in various industries.
