“…By shortening of the electrode distance, the current skips to value ca. 350 µA and the discharge switches into a glow discharge [9]. Some electric characteristics of used discharges are described in [10].…”

The Influence of Parameters of Stabilized Corona Discharge on its Microbicidal Effect

2011

This work presents the study of microbicidal effects of positive flashing corona, negative pulseless corona and glow corona discharges and the comparison of their efficiency in the point-to-plane arrangement in water suspension. The flashing corona seems to be the most effective one, however the interval of optimal parameters is wide. The total inhibition of microorganisms becomes after 75 s or 8-10 min of exposition for bacteria or yeast, respectively. A hypothesis explaining the different sensitivity of various microbes is postulated.

“…This electrode geometry was developed by the group of Akishev et al [5][6][7][8] and was successfully tested for the removal of SO 2 and NO x [9]. Vertriest et al applied a large scale laboratory multi-pin-to-plate negative glow discharge for the removal of VOCs and discovered that molecules containing a double carbon bond have the lowest energy requirement for decomposition [2].…”

The decomposition of trichloroethylene (TCE) in air by non-thermal plasma was investigated with a multi-pin-to-plate direct current (DC) discharge at atmospheric pressure and room temperature. The effects of various operating parameters on the removal efficiency (RE) were examined. The experiments indicated that for low energy densities higher removal could be obtained with positive corona. For negative corona and 10% relative humidity (RH) a maximum RE of 99.5% could be achieved at 1100 J L -1 . Formation of byproducts was qualitatively analyzed in detail with FT-IR spectroscopy and mass spectrometry. Detected by-products for negative corona operated at 300 J L -1 and 10% RH include dichloroacetylchloride, trichloroacetaldehyde, phosgene, ozone, HCl, Cl 2 , CO and CO 2 . The highest RE for TCE was achieved with a relative humidity of 19%.

“…For more details about this discharge denominated as pulseless glow, see our previous paper [37], where several stabilized discharges are studied. For other information about the corona discharge stabilization and its characteristic, see, for example, papers [38,39]. e aerosol of pure water or 10% hydrogen peroxide was generated by the ultrasonic nebulizer (Lucky Reptile, Super Fog SF-1) and mixed with the air; the volume of nebulized water or hydrogen peroxide in the air mixture was 0.40 ± 0.03 ml/l (determined by the weight loss).…”

e inactivation e ect of the combination of nonthermal plasma and hydrogen peroxide aerosol for the microbial decontamination of inner surface of cylindrical container buckets is studied on one bacterial and seven lamentous micromycete species and on airborne-contaminated cups. While the decontamination by single nonthermal plasma or hydrogen peroxide is not observable after 120 s, the strong decontamination by their combination occurs after 30 s of exposure. Moreover, observed total elimination of airborne contamination of plastic cups predetermines this method as a suitable alternative to the currently used method based on the application of hydrogen peroxide.
