“…The results obtained in these experiments show that the pH tended to be relatively more basic after the pulsed high voltage was applied to the plasma reactor. This makes the system suitable for the removal of microorganisms in the water, as supported by Li, et al [11]. Future studies are needed to study the effects of pH on the removal of microorganisms.…”

“…Sugiarto [10] obtained the degradation efficiency of organic pollutants in water in different discharge states of a needle-to-plate electrode system. Li, et al [11] also reported that the degradation efficiency of phenol in water increased with the increase of the pulsed peak voltage and treatment time. Although these discharge plasma reactor systems have a higher removal efficiency for organic pollutants, there are still many problems that need to be investigated before industrialized application of pulsed discharge plasma in wastewater treatment/disposal can be realized, such as the oxidation of discharge affecting the removal efficiency of microorganisms.…”

Abstract.A pulsed high voltage was used to remove microorganisms in drinking water. The effects of the pulsed high voltage on pH, conductivity, temperature and oxidation reduction potential (ORP) of the drinking water were investigated. The observed results show that the removal efficiency with respect to fecal coliforms and total coliforms increased with the increase of the pulsed high voltage. The removal efficiency for microorganisms such as fecal coliforms and total coliforms was in the range 25-100% and 44-100%, respectively, after the water was exposed to a pulsed high voltage of 5-10 kV for 60 minutes. An increase of the pulsed high voltage caused a decrease in the conductivity and ORP with operational time.

“…A similar phenomenon was observed in reports by Huang et al [56] for the degradation of methylene blue by atmospheric DBD plasma. Superior phenol removal efficiency was achieved at pH 10.2 using a gas-liquid phase pulsed discharge plasma reactor [57]. Sun et al [58] also reported that the formation of reactive species are pH dependent.…”

A B S T R A C TIn this study an atmospheric air plasma reactor was studied for the degradation of HA and THMs in water. Plasma treatment showed significant breakdown efficacies for HA and THMs. At an applied voltage of 80 kV about 93% of HA and >70% of THMs were degraded after 15 min and 30 min treatment time respectively, with the degradation following a first order kinetic model. Plasma induced reactive species including nitrates and H 2 O 2 were quantified in the treated water. The results of FTIR analysis revealed that the molecular structure of HA was altered by the plasma treatment, with a decrease in aromaticity observed.

“…These chemical reactants are effective in degrading organic pollutants. The removal efficiency of the organic contaminants increases with an increase of the applied voltage and the treatment time [6][7][8]. The aim of the present work was to study the performance of the DBD system as an alternative for treating POME.…”

Abstract. In the palm oil industry, open ponding, aerobic and anaerobic digestion, physicochemical treatment and membrane filtration are generally applied as conventional treatments of palm oil mill effluent (POME). In this study, a sand filtration-dielectric barrier discharge (DBD) system was investigated as an alternative process for treating POME. This system can reduce land usage, processing time and costs compared to conventional systems. The removal efficiency of chemical oxygen demand (COD), biological oxygen demand (BOD 5 ), and oil-grease in relation to the applied voltage were studied. Furthermore, the pH and temperature profiles were investigated. The obtained results indicate that the removal efficiency of COD, BOD 5 , and oil-grease increased with an increase of the applied voltage. The electrical energy consumption needed is about 10.56 kWh/L of POME.
