  • 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). ...

  • Using Ozone Disinfection for EDC Removal

    Clark County Water Reclamation District (CCWRD) serves the suburban area in and around the city of Las Vegas. The Las Vegas Valley is served by three treatment plants, which all discharge to the Las Vegas Wash. The wash empties into the Las Vegas Bay of Lake Mead. Lake Mead is also the source of drinking water for the Las Vegas Valley. In 1996 USGS reported symptoms of estrogen exposure in carp ...

  • 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 ...

  • Ålands Water chooses reliable Primozone system

    Primozone Production AB installed a new ozone treatment system on the island of Åland, Finland, in June 2007. The plant supplies 475 m³/h of drinking water to the population of Mariehamn, which is the larger part of Åland's 27.000 inhabitants, and which doubles during the summer season. Åland is an archipelago of 6.500 islands. The process disinfects the water and removes ...

  • Case study - City of Montreal upgrade of Atwater and Des Baillets water treatment plants

    Sidestream Venturi Injection—Basin Nozzle Manifold Contacting System. Montreal, Quebec, Canada The Problem: In 2001, a water quality audit revealed that two of the largest drinking water plants in the City of Montreal were out of compliance with Quebec’s latest water quality rules. In response to the audit, the city upgraded the 1,400 MLD Atwater and the ...

  • Profile of Ozone/Bromine Sanitation Systems for City of Tucson Municipal Pools

    Due to the inherent risks associated with the use of chlorine gas as a sanitizer for the City of Tucson’s twenty-six municipal swimming pool sites, I found myself in search of an alternative water sanitation method. The challenge was clear; find a system that would be safer to manage than gas chlorine, yet yield the same favorable sanitation and water quality results. Since all the sites ...

  • A comparison of the Eulerian and particle tracking approaches for prediction of ozone contactor performance

    The Eulerian and particle tracking approaches, two commonly utilized numerical methods, were evaluated for modelling drinking water ozone disinfection systems. The Eulerian approach predicts disinfection performance by solving an advection-diffusion equation. Alternatively, the particle tracking (Lagrangian) approach calculates disinfection efficiency by numerically introducing particles into the ...
