  • Case study - An air/ozone Sparge curtain to protect a municipal supply well

    Description Releases of petroleum contaminants from a retail gasoline station in a medium-sized California Central Valley town threatened a municipal supply well immediately adjacent and approximately 200 ft downgradient to the station. Methyl tert-butyl ether (MTBE) was present in groundwater concentrations up to 30,000 micrograms per liter (µg/L) and GRO up to 33,000 ...

  • The economic pre-treatment of coal mine drainage water with caustic and ozone

    Coal mine drainage waters are low in pH with varying amounts of iron and manganese and are generally brackish. The Austar Coal Mine in NSW, Australia, sought alternatives to their current lime dosing as the pre-treatment before the downstream reverse osmosis plant. Undesirable operating aspects of the current system include manganese and gypsum scaling/fouling, the need for anti-scalants and ...

  • Comparison of simple ozonation and direct hydrogen peroxide processes in TNT removal from aqueous solution

    Oxidation of 2,4,6-trinitrotoluene (TNT) using simple ozonation and direct hydrogen peroxide was studied. An analytical method based on the HPLC (high performance liquid chromatography) system was used for TNT detection. The influence of parameters such as pH of the solution (3–10), initial TNT concentration (10–100 mg/L), dosage of ozone (0.2–1 g/hr), H2O2/TNT molar ratio (250–1,000), ...

  • Degradation of Reactive Yellow X-RG by O3/Fenton system: response surface approach, reaction mechanism, and degradation pathway

    O3/Fenton for the treatment of effluent containing Reactive Yellow X-RG is investigated. The response surface methodology is applied to study the main and interactive effects of the parameters. With the initial dye concentration being controlled at 300 mg L−1, the optimized conditions for wastewater treatment are 3.68, 29.19 and 18.49 mg min−1 for initial pH, mole ratio of ...

  • Ethylene removal through oxidation versus Ozone

    Fruit constantly emits ethylene inside the chambers. To efficiently reduce the concentration of ethylene in these spaces, it needs to be eliminated at a speed that is faster than the production ratio of the fruit. This is achieved when the airflow that passes through the machines in one hour is equal to the volume of the chamber.   Depending on the chamber's volume, Bioconservacion ...

  • Ethylene Removal in Cold Storage: Ozone versus Potassium Permanganate

    The preservation of fruit and vegetables in cold storage is currently an indispensable fact, although the cold in itself does not resolve the problem of preservation. Ethylene is a gas that is produced naturally by vegetable tissues. It acts as a vegetable hormone and principally controls the processes of ripening and senescence. Ethylene accumulates in low concentrations in areas ...

  • Biocidal Products Regulation - White Paper

    The European Biocidal Products Regulation (Regulation (EU) No. 528/2012) stipulates that biocidal products may only be made available and used on the market if they are certified in accordance with this regulation. Unlike the previous biocidal products legislation, so-called “in-situ” procedures such as electrolysis, chlorine dioxide and ozone now also fall under this certification ...

  • Limitations of the removal of cyanide from coking wastewater by ozonation and by the hydrogen peroxide-ozone process

    The purpose of this study is to compare the efficiency of ozonation and the hydrogen peroxide–ozone process for the removal of cyanide from coking wastewater. The most efficient oxidation process is combined with coagulation–flocculation–decantation and lime–soda ash softening pretreatments. The oxidation in aqueous solution and industrial wastewater (at pH 9.5–12.3) by O3 was carried out ...

  • Trade SIA on the Environmental Goods Agreement OZONATOR - Case Study

    An innovative technology has been developed in Canada for the processing of medical and bio-hazardous waste using ozone as the sterilizing agent. Ozone is generated and is produced from ambient air and any residual ozone is converted back to oxygen, resulting in zero emissions. Waste is sterilized at room temperature without heat, steam, chemicals, flames, exhaust, odours with nothing to drain or ...

  • Removal of pharmaceutical residues using ozonation as intermediate process step at Linköping WWTP, Sweden

    Pilot tests as basis for the design, implementation and operation of a future full-scale oxidation plant completing the existing sewage treatment in Linköping, Sweden, were performed. Using an ozonation step between bio-sedimentation and post-denitrification processes, the primary goal was the removal of the highest priority substances to effluent water levels that will not cause adverse ...

  • Application of Ozone in Cooling Water Systems

    The first comprehensive study - bench-top laboratory investigations, pilot scale testing, and critical monitoring and evaluation of field applications - addressing the effects of ozone as a stand-alone cooling water treatment program is presented. The study also represents the first critical comparison of ozone-treated systems with non-treated systems. Excellent corrosion control can be attained ...

  • 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 ...

  • How Pain Keeps us from Acting on Climate Change

    In my daily work, I read a lot of online articles about climate change—both the science and the politics—and out of curiosity I’m invariably drawn to the comments section at the end of the page (first rule of the internet—never read the comments!). What I’ve observed is that these comments tend more often than not to be variations on one of the following themes: ...

  • Comparison of O3 + GAC, O3 + H2O2 + GAC, and GAC unit operation on natural organic matter and taste and odor causing compounds removal using a pilot plant study

    Removal of natural organic matter (NOM) and taste and odor problems in drinking water are a sensitive issue in municipal water treatment plants. This study investigated the effectiveness of ozone (O3) + granular activated carbon (GAC), O3 + hydroperoxide (H2O2) + GAC, and GAC processes using a pilot scale plant to remove NOM and geosmin (50–1,000 ng/L), and ...

  • 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 ...

  • 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 ...
