Ozone Production Efficiency in Highly Polluted Environments
Current Pollution Reports, 2018When developing ozone control strategies, the empirical kinetic modeling approach curve cannot easily be applied to practical problems. On this basis, the ozone production efficiency (OPE) is proposed as an indicator to represent the effects of NOx on ozone. The research results of the OPE are reviewed and include the definition and calculation of OPE,

Abstract Understanding the drivers of urban ozone (O3) formation is challenging and requires uncovering the non-linear relationship between O3 and its precursors. We used a novel method to differentiate between background O3 levels and local photochemical O3 generation using the observation-based O3 production efficiency (OPE) from decade-long ...

Efficiency of Ozone Production in Coplanar Dielectric Barrier Discharge
Plasma Chemistry and Plasma Processing, 2019Efficient generation of ozone by cold atmospheric plasmas is interesting for sterilisation and decontamination of thermally-sensitive surfaces. This paper presents a study of robust coplanar dielectric barrier discharge (DBD) for generating atmospheric pressure plasma in synthetic air and in oxygen.

Productivity and Efficiency of Ozone Synthesis in Coplanar Discharge Arrangements
Ozone: Science & Engineering, 2003In order determine the potential of coplanar discharge arrangements with short electrode distances for the production of ozone, a numerical model of the discharge behavior has been developed. The temporal and spatial distributions of the discharge parameters e. g. those of the field strength, the densities of the charged particles in the gas region and

Optimization of filtration efficiency and ozone production of the electrostatic precipitator
Journal of Aerosol Science, 1986An electrostatic precipitator is an air cleaner in which particles are first charged by an electric current coming from corona wires in high voltage. Then the particles are collected by the electric field between collecting plates. The principle of the operation of an electrostatic precipitator is shown in Fig. 1.

Physica Scripta, 2022
Abstract The spatial and temporal evolution of the ozone density has been measured in a 1 cm electrode gap tip to plane positive pulsed corona discharge in air at atmospheric pressure with no gas flow. It was expected to observe a higher ozone density in the vicinity of the discharge gap but ozone has been found at a quasi uniform ...

Increased efficiency of ozone-production by electric discharges
Electrochimica Acta, 1973Abstract Present day ozonisers reach efficiencies from 4 to 8 per cent. In an attempt to increase the efficiency an ozoniser is analysed in view of chemical reactions and electrical theory. The ozoniser has two functions: it produces atomic oxygen and constitutes a reactor to form ozone.

Application of Freestanding Perforated Diamond Electrodes for Efficient Ozone-Water Production
Electrochemical and Solid-State Letters, 2006The application of diamond electrodes is promising for electrolyzing water to produce ozone because of their superior chemical and dimensional stability, as well as their large overpotential for the oxygen evolution reaction. A freestanding conductive diamond plate was perforated to prepare a freestanding perforated diamond electrode, which was ...

Efficiency and Products Investigations on the Ozonation of 2‐Methylisoborneol in Drinking Water
Water Environment Research, 20092‐Methylisoborneol (MIB) is a terpenoid produced as a secondary metabolite by some cyanobacteria and actinomycetes and thus can be present in some drinking water source waters. The removal efficiency, products, and degradation pathway of MIB in drinking water by ozonation were studied.

Abstract Biohydrogen production from seagrass (SG) has gained much attention due to their chemical composition (carbohydrate rich biomass). In this study, an attempt was made to enhance the biohydrogen production from sea grass through novel ozone coupled rotor-stator homogenization (ORSH).
