“…For example, carbon monoxide is a readily biodegradable compound; nevertheless its very low solubility in aqueous medium makes its removal from polluted air in bioreactors a challenging task. 4,5 Other parameters, such as the relative humidity in packed bed bioreactors, will also affect the biodegradation efficiency. 2 A few decades ago several industrial pollutants were thought not to be biodegradable at all because of their anthropogenic nature (i.e.…”

Bioprocesses have been developed as relatively recent alternatives to conventional, non-biological technologies, for waste gas treatment and air pollution control in general. This paper reviews major biodegradation processes relevant in this field as well as both accepted and major innovative bioreactor configurations studied or used nowadays for the treatment of polluted air, i.e. biofilters, one-and two-liquid phase biotrickling filters, bioscrubbers, membrane bioreactors, rotating biodiscs and biodrums, one-and two-liquid phase suspended growth bioreactors, as well as hybrid reactor configurations. Some of these bioreactors are being used at full-scale for solving air pollution problems, while others are still at the research and development stage at laboratory-or pilot-scale.

“…The precursor Mn0.5 is with magnetite structure, which has five Raman active modes (A 1g + E g + 3T 2g ) of cubic spinel. Its Raman spectrum shows five distinct bands at approximately 193 (T 2g(1) ), 324 (T 2g(2) ), 453 (E 1g ), 585 (T 2g (3) ) and 668 (A 1g ) cm −1 , respectively, close to the active phonon modes of magnetite [27]. After calcination, the Raman spectra show obvious variations.…”

“…With the increasing use in of biofuels [2], HCHO is a typical pollutant in both indoor and outdoor air, which is a hazard to human health and induces photochemical pollution [3][4][5]. Enormous efforts have been devoted to decreasing the HCHO concentrations in the air to satisfy the stringent environmental regulations.…”

“…With high consumption in the industrial processes such as the manufacturing of wood products and building materials, petrochemical engineering and combustion processes [2,3], its emission has become a great threat to the environment and human health [4]. Therefore, the abatement of HCHO before emission is highly desirable, and several techniques, e.g., adsorption [5], condensation [6], photo-catalysis [7] and catalytic oxidation [8], have been developed.…”
