  • Ozone for Waste water Treatment

    Ozone has been used for many years to treat pathogens such as bacteria and algae in water for applications such as drinking water supplies and air conditioning system cooling water. More recently, most water bottlers have adopted ozone. Ozonated water for treatment of fruit, vegetables, fish, etc. in the U.S. awaited the GRAS approval. Now that has happened, and projects are emerging everywhere. ...


  • Ozone in Cooling Water Treatment

    When commercial ozone generators were first introduced for cooling water treatment, they were marketed as a stand-alone treatment, a cure-all or panacea. We now know this is not the case. Because there have been many misconceptions regarding ozone, this article is intended to review the basics of ozone, its true capabilities and limitations, and its potential benefits in cooling water treatment ...

  • 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 ...

  • Ozone toxicology and guidelines for safe use in cooling water ozonation systems

    Abstract Ozone, like all oxidizing gases, is potentially harmful if human exposures occur at a significant concentration for a sufficient duration. This paper discusses the physical properties of ozone, current exposure standards, toxicology of ozone, and recommended safety practices for safe operations in cooiing water treatment ...

  • The Use of Ozone in Cooling Towers

    Ozone has been successfully applied to industrial cooling water systems with the resultant improvement in operational efficiency due to increased heat transfer, reduced system corrosion, improved environmental impact and reducedon-going chemical expenditure. The aim of this paper is to provide practical advice on the options available for the application of ozone and the potential benefits which ...

  • Sanitation Using Ozone & Chlorine

    For nearly 100 years, ozone has been used all over the world for water sanitation. It is nature’s strongest oxidizer and has a byproduct of pure oxygen. Chlorine, on the other hand, is a very effective, time-proven chemical, but is ineffective against hard-to-kill microorganisms such as cryptosporidium. It also has some unpleasant byproducts. Together, however, these two substances can ...

  • Ozone for Bottling Applications

    Over the last decades there has been an increasing demand for water in bottles, cans, etc.. This demand or trend, which has many reasons beyond the scope of this paper, has drawn manufacturers' attention to the necessity for specialised filling techniques. One particular problem that plagues the bottled water industry is the microbial quality of the bottled products. In the more recent past, ...

  • Chemistries of Ozone for Municipal Pool and Spa Water Treatment

    Ozone generated by ultraviolet (UV) radiation is used in North America for treating (mostly residential) spa and pool waters almost exclusively, while only a handful of North American municipal pools and spas are using ozone generated by corona discharge technology in accordance with well–established German teachings. On the other hand, several thousand European municipal swimming pools and ...

  • Ozone is Not Just for Residential Potable Water Treatment

    It has been over 170 years since the d iscovery of the ozone (O3) molecule. Since that time, scientists and engineers have been testing and evaluating ways to use ozone in many different processes, from water and air treatment to surface and food sanitation. The evolution was somewhat slow in the early days, taking nearly 50 years before Europeans found, in 1886, that ozone could be used for ...

  • Ozone systems for beginners

    This paper is intended for people who know a cooling tower when they see one but have little or no knowledge of their care or what part ozone plays. I have tried to make this as simple as possible and there is even a block diagram on the last page to help you out. Ready? Okay, here is what you need to know first: The sole function of ozone use in evaporative cooling towers is to disinfect water. ...

  • Ozonation Pretreatment to MIEX® Process

    The MIEX®DOC process is a proven technology for the removal of dissolved organic carbon (DOC) from potable and wastewater sources. Occasionally, waters are found to contain an intractable fraction of organic carbon and in such instances, the performance of the MIEX®DOC technology can be enhanced with ozonation. Ozonation is believed to be effective in partially oxidizing organic material and ...

  • Ozone Based WasteWater Treatment

    The Australian Water Association held an international conference on 'Onsite and Decentralized' waste water treatment systems in Benalla, VIC. This was the abstract presented by Kyle Greene, Seair Canada Head of Research and Development. These portable wwtps are used in the extremes of northern Canada oil, gas and mining camps. Featuring: Heavy duty steel container, industrial weather coated, ...


  • Infectious Diseases and Ozone

    OZONE kills all known Virus & Pathogens.There is a lack of information on the proper handling and disposal of the medical waste associated with diseases like Ebola, which is a level 4 bio-hazard. The quantity of medical and biohazard waste that is generated during a outbreak in a hospital can increase five fold and during the treatment of Ebola patients and other highly contagious diseases, ...

  • Drinking Water Aesthetics Improve with Ozone Treatment

    High quality water sources for municipal use are dwindling, forcing utilities to seek alternate water sources. Many times, aesthetics are the only problem preventing the use of these alternate water sources for potable purposes. Although typically used as a disinfectant, ozone offers municipal water purveyors the benefits of being the strongest commercially available oxidizing agent (Table 1). ...

  • Trihalomethane formation in ozonated and chlorinated surface water

    Abstract The relatively recent discovery of disinfection by-products has driven the main regulatory organisms to set maximum contaminant levels for certain substances in drinking water. Trihalomethanes can be deemed as the most important group of by-products in chlorinated surface waters. The present work has focused on trihalomethane formation in a full-scale water treatment plant. We studied ...
