  • Evolution of Industrial Ozone Generation

    A vast selection of different ozone generator designs is commercially available on today’s market. In large-scale applications, the ground electrode is designed as gas/water tube heat exchanger, which is filled with tubular high-voltage electrodes on the gas processing side. Available constructions differ in diameter, length and arrangement of the tubular electrodes, type and support of the ...

  • Feedgas For Modern High-Performance Ozone Generators

    The traditional way of producing ozone is by means of Dielectric Barrier Discharge or so-called Silent Electrical Discharge. Typically, dry feedgas - either air or oxygen - is passed through a gap formed by a high voltage electrode and an earth electrode. When high voltage at high frequency is applied to the high ...

  • Efficient generation of mixed oxidant disinfectants: parametric study on electrode materials and operating conditions

    Electrochemical disinfection is an efficient method used for treatment of drinking water. It has great environmental compatibility as compared to conventional disinfection methods. In this study, the effects of the electrode materials and working conditions were investigated. The experimental results show that the type 1 (iridium oxide-coated anode and cathode) electrode system generated a ...

  • A Discussion on Ozone Chemistry

    MEMBRANE AND APPLICATION DEVELOPMENT 1.0 INTRODUCTION The ability of ozone to effectively treat wastewater is dependent on the nature of contaminant in question. For example, ozone will readily remove color from a dye solution, but has much more difficulty reducing the biochemical oxygen demand (BOD) of a sucrose stream. These differences in ozone effectiveness are ...

  • Ozone Brings Better Bottled Water

    The proliferation of bottled beverages worldwide and an increased awareness of consumer health issues have beverage bottlers rethinking how to keep their liquids safe for consumption. One problem they face is the need to deliver a product that is free of bacteria, to provide extended shelf life and product quality. Ozone has quickly become the disinfectant of choice among water bottlers ...

  • Highly efficient treatment of industrial wastewater by solution plasma with low environmental load

    Advanced oxidation techniques are efficient processes to dispose of organic contaminants in industrial wastewater with low secondary pollution. The solution plasma technique was featured as an advanced oxidation technique with low secondary pollution and high efficiency. However, the solution plasma technique reported previously could only treat wastewater of less than 200 mL owing to the ...

  • Pulsed corona discharge for degradation of aqueous humic substances

    The research into oxidation of aqueous humic substances (HS) with pulsed corona discharge (PCD) was undertaken to estimate the energy efficiency of the treatment. The PCD system consists of a voltage pulse generator and reactor, in which the gas-phase discharge generating OH radicals and ozone treats the water showered between electrodes. The influence of HS initial concentration, pulse ...

  • Electrochemical degradation of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in groundwater

    Perfluoroalkyl and polyfluoroalkyl substances (PFASs) represent hazardous pollutants and are frequently detected in the environment, e.g. in contaminated groundwater. PFASs are persistent to biodegradation and conventional oxidation processes such as ozonation. In this study electrochemical degradation of PFASs on boron-doped diamond (BDD) electrodes is demonstrated. Experiments were performed ...

  • Welding fume hazards

    Welding is tough work.  Not many who begin as welders retire as welders.  Eventually practically every welder develops cataracts.  Neck and back problems are also a foregone conclusion. There is also a long list of possible health problems depending on the type of welding.  Recently, the Occupational Health and Safety Administration (OSHA) identified hexavalent chromium as a ...

  • Controlling Bacteria In a Clean Room Environment

    Maintaining the integrity of a cleanroom is a constant battle. The first step to deciding which method, or combination of methods, to employ is to identify the prime sources of contamination. There are three prime sources of contamination through which the integrity of a cleanroom might be breached. First, there is the human element. While many processes might be automated, many situations remain ...
