  • 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 ...

  • Hotels Put Ozone to Work

    Growing operational costs and lower-than average occupancy rates spurred Apple Farm Inn and Suites, San Luis Obispo, Ca., to explore economic and facility-efficiency benefits obtained through the installation of an ozone laundry system. At the Apple Farm Inn laundry facility, an evaluation lasting several months was conducted in late 2006 into 2007, comparing the costs of laundering by ...

  • 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 ...

  • Introduction to Ozone Injection Technology

    Untitled Document Ozone is a highly reactive chemical that has proven to be effective in destroying a wide variety of organic chemicals, including MtBE and chlorinated VOCs. ...

  • 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, ...


  • Ozone treatment for cooling towers

    Abstract The use of ozone as a maintenance treatment for cooling towers has good potential for operation and maintenance savings in the Federal secior. A small amount of ozone acts as a powerful biocide thai decreases or nearly eliminates the need to remove quantities of water from the cooling tower in order to decrease the concentration of organic and mineral solids in the system. ...

  • 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 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. ...


  • Sophisticated control system - effective ozone generator

    At the Freshwater Institute in Shepherdstown, West Virginia (USA) they are convinced that ozone water treatment is essential to optimize production in water recirculating aquaculture systems (RAS). Scientists at the Freshwater Institute have been studying ozonation for years but have never before used such a sophisticated ozone generator as the Primozone® Ozone Generator. The Freshwater ...

  • Ozone-based reclamation of an STP effluent

    The system ozone and hydrogen peroxide was used to reclaim wastewater from the secondary clarifier from a Sewage Treatment Plant (STP) of Alcalá de Henares (Madrid-Spain). The assays were performed by bubbling a gas mixture of oxygen and ozone, with ~24 g Nm-3 of ozone concentration, through a volume of wastewater samples for 20 minutes at 25°C . The removal of dissolved ...

Ozone has quickly become the disinfectant of choice among water bottlers ...

  • Is your ozone generator up to the job?

    After over a decade of building and supplying many ozone generators for water treatment all over the world, I had noticed that we hardly sell anything locally. It seemed strange to me, so I decided to call several different local water treatment professionals to find out what was the reason behind this. I asked them if they had ever used an ozone generator for water treatment. To my surprise, ...

During this evaluation, the range of alternatives was expanded to include ozonation and other advanced oxidation processes (AOP), to examine ...

  • A study on the effects of ozone dosage on dissolved-ozone flotation (DOF) process performance

    Dissolved-ozone flotation (DOF) is a tertiary wastewater treatment process, which combines ozonation and flotation. In this paper, a pilot-scale DOF system fed by secondary effluent from a wastewater treatment plant (WWTP) in China was used to study the effect of ozone dosage on the DOF process performance. The results show that an ozone dosage could affect the DOF performance to a large extent ...
