  • 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 Based WasteWater Treatment

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 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 ...

  • Treatment of waste thermal waters by ozonation and nanofiltraton

    After their use for heating, e.g. in greenhouses, waste thermal waters may cause environmental problems due to their high contents of ions, and in some cases organic matter (associated with an oxygen demand) or toxic compounds. The aims of this work were to decrease the high organic content of waste thermal water by a combination of ozone treatment and membrane separation, and to investigate the ...

  • 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). ...

  • Ozone disinfection: main parameters for process design in wastewater treatment and reuse

    Wastewater disinfection by ozone was investigated at pilot and full scale on different wastewater effluents and two types of ozone reactors. It was demonstrated that water quality and, in particular, suspended solids and organic content strongly influence the required ozone dose for a given level of disinfection. The increase in contact time and residual ozone concentration did not improve the ...

  • Ozone Based AOP process for refractory COD reduction in industrial waster water

    Introduction In recent years improvements  in ozone based advanced oxidation technology efficiencies have lowered capital and operating expenses, improving the viability of the use of ozone as the main oxidant. An investigation into alternatives for refractory COD removal which is economically attractive and do not produce sludge lead to an evaluation of ...

  • Pilot scale experiments on surface water treatment sequence including ozonation and adsorption processes

    The paper presents results of the experimental studies on combined ozonation and activated carbon adsorption processes at the Water Treatment Plant (WTP) at Cracow (Poland). The study focused on the selection of an appropriate location of an ozonation process within the treatment scheme and on the choice of activated carbon grade for adsorption. Analysis of process efficiency in the proposed ...

  • 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 ...

  • Self-Cleaning Filtration for Pretreatment of Membrane, UV and Ozone Water Treatment Systems

    Recent field data has shown the effectiveness of automatic self-cleaning filters in removing suspended solids down to less than 3 microns in size without flocculents, pre-coats or granulated media. Pre-treatment of ozone systems is often needed to remove organic solids that would utilize high amounts of ozone during oxidation leaving little for complete disinfection. Selfcleaning screen filters ...

  • Optimization of the ozone dosage at the drinking water treatment plant of Kluizen

    De Watergroep, a Flemish drinking water utility, aims to optimize the ozonation process at the Kluizen surface waterworks in order to obtain sufficient inactivation of pathogenic micro-organisms while minimizing the formation of bromate. In literature, the inactivation of micro-organisms is described as a first order process in ozone exposure (ozone concentration multiplied by exposure time or ...

  • Membrane processing for water treatment in the semiconductor industry

    It is the aim of high-purity water production to either fully eliminate organic and ¡florganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology ...

  • 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. ...

  • Perfluorinated chemicals (PFCs) in water purification plants (WPPs) with advanced treatment processes

    A series of perfluorinated chemicals (PFCs) surveys were conducted in two water purification plants (WPPs) having ozonation and granular activated carbon (GAC) filtration processes. In each plant, six different processes samples (source water, influent, coagulation-sedimentation effluent, ozonation effluent, GAC filtration effluent, and final tap water) were collected for two times and eight PFCs ...

  • Scale-up of the MIEX® DOC Process for Full Scale Water Treatment Plants

    The MIEX® DOC Process is a new process developed by Orica Watercare, South Australian Water Corporation and the CSIRO for the removal of dissolved organic carbon (DOC) from drinking water. Results from scale up of the process to a 170m3/day pilot plant have been reported previously (Nguyen, 1997). The process has now been successfully scaled up and trialed on a 1000m3/day pilot plant located at ...

  • Ozone as a Disinfecting Agent in The Reuse Of Wastewater

    More and more countries are taking measures to reuse wastewater. This has been prompted by the ever decreasing availability of good quality raw water and the increasing cost of producing potable water. Disinfection is a major treatment step in the direct reuse of reclaimed wastewater to ensure environmental and public health protection. “Disinfection is the destruction, inactivation or removal of ...

  • “Ozone” and “GAC filtration” synergy for removal of emerging micropollutants in a drinking water treatment plant?

    Ozonation plays an essential role in water disinfection to inactivate viruses, bacteria and some parasites (Giardia). Ozone treatment rates to attain disinfection goals also result in oxidation reactions of emerging pollutants. Pharmaceuticals–except Ciprofloxacin–are very reactive to ozone: they are removed as early as the transfer compartment outlet even at an ozone treatment rate ...
