Anticipation Of Vocs And Haps Compounds By Using Of Appropriate Technology

ABSTRACT- Most of the manufacturing industries like paints chemicals pharmaceuticals Textiles petrochemicals are produce volatile organic compounds VOCs hazardous air pollutants HAPs and odors as part of their manufacturing process. It should be affect for the nature of environment and human health. So it can be consider that these kinds of pollutant problems are reduce by using of bio or chemical oxidation process. From this method dealing with these industrial air emissions include masking agents or activated-charcoal filters or thermal- or catalytic-oxidization systems that use natural gas to burn off the pollutants. However as the world struggles to increase energy efficiency to cut both costs and carbon emissions industry is investigating lower-impact and more efficient methods of controlling the release of harmful pollutants into the atmosphere. Bio or chemical oxidation is an air pollution control technology that uses naturally-occurring to biologically absorb and digest industrial emissions converting them to carbon dioxide water and mineral salts. The process typically involves drawing a contaminated air stream through some type of medium that hosts a community of microbes including either bacteria or fungi or a combination of the two. The process is referred to as bio-oxidation although it can occur in bio-trickling filter and bio-filter units either alone or in combination all of which operate at a different media wetness based on the requirements of the appropriate microbes and the targeted pollutant.
