| USE OF MODIFIED CARBON BIOFILTER IN CASE OF AKTOBE TOWN, KAZAKHSTAN
Zhaksybayeva A.S. al-Farabi Kazakh National University zhaksybayevaa@gmail.com Nowadays Aktobe’s air environment suffers from emissions of industrial and transport sectors companies that cause air pollution, unpleasant odour and acid rain. Vast enterprises determining the degree of air pollution are JSC “CNPC-Aktobemunaigas”, LLP “KazakhOil Aktobe”, UMG “Aktobe”, JSC “Intergas Central Asia”, branches of JSC “TNK “Kazchrome”, LLP “Copper Technology” which account for 42% of pollutant emissions into the atmosphere. In order to decrease the level of hazardous pollutants in the air the carbon filters are currently of great interest. Due to its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 500 m that adsorb all the toxic compounds from the air or aqueous solution. Despite the fact, that they were known as water purifiers, nowadays they are used as promising air filters as well. It has been found that charcoal can adsorb mostly all the gases that lead to pollution and disagreeable smell for recent years in Aktobe town. However, carbon filters have also limitation, i.e. filters need to be changed extremely frequently. In order to remove this shortage hypothetically it could be resolved by adopting biofilm based on perspective strains of microorganisms. Biofilm will be attached to the surface of the carbon which will serve as the substrate for microorganisms that will metabolically modify or convert the adsorbed chemicals by decomposing and consequently feed by them. This modification will increase the durability and service life of carbon air filters that is also economically efficient. Scientific adviser: PhD Akimbekov N.S. |
