AbstractWastewaters polluted with non-biodegradable volatile organic compounds (VOCs), such as aromatic substances, present a growing problem meeting no adequately affordable technological response. Low-temperature plasma generated in the gas-phase pulsed corona discharge (PCD) presents competitive advanced oxidation technology in abatement of various classes of pollutants, although the process parameters, the pulse repetition frequency and the liquid spray rate, require optimization. The experimental research into aqueous benzene oxidation with PCD was undertaken to establish the impact of the parameters to the energy efficiency. The oxidation reaction was found under the experimental conditions to mostly proceed in the gas phase showing little influence of the pulse repetition frequency and the gas-liquid contact surface. Oxidation of benzene and, presumably, other volatile pollutants in the volume of PCD reactor compartment presents an effective strategy of aqueous VOCs abatement.

General Decline

There was investigated the effect of barrier and spark discharge low temperature plasma on water containing the cells of Escherichia coli (Escherichia coli), hay bacillus (Bacillus subtilis) and yeast (Saccharomyces cerevisiae). There was shown a general decline in the concentration of viable microbial cells after the treatment of suspensions. There was especially marked the detrimental effect of the method on the viability of sanitary-indicative coliform bacteria in the water.
