    The North Texas Metropolitan Water District began working to add ozone to its four interconnected water treatment facilities which operate as the Wylie Water Treatment Plant (WTP).

92. Improving The Quality Of Tertiary Effluent For Indirect Potable Reuse With Geographic Constraints 9/5/2018

    The Mazzei Sidestream Venturi Injection – Pipeline Flash Reactor System provides a feasible alternative for dissolution of ozone at the Clark County Water Reclamation District (CCWRD) in Las Vegas, because it allowed for flexibility in basin design to meet geographic site constraints.

93. Mitigating Environmental Impact Of Gold Mine's Wastewater Through Ozone Oxidation And Aquifer Re-injection 9/5/2018

    Installing and operating an ozone oxidation system for wastewater remediation at a gold mine located in a remote region of Alaska is full of challenges.

94. Update And Upgrade Of Ozone Dissolution System At Southwest Water Treatment Plant 9/1/2018

    The burden of the unavailability of replacement parts for the aging generators and the FBD basins' high maintenance motivated the Orlando Utilities Commission's Southwest Water Treatment Plant to update and upgrade the plant’s ozone system.

95. Ozone Resolves Hydrogen Sulfide And Color Issues In Well Water 9/1/2018

    A potable water plant in Eastern Angelina County, Texas,  serves over 2,000 rural customers.

96. Maximum Ozone Transfer Efficiency Across Broad Range Of Water Flow 8/25/2018

    The design team for the intermediate ozone system at Buckingham Water Treatment Plant, Quebec, had limited space available for ozone contacting for the plant’s 1.3 – 7.4 MGD flow, so a standard fine bubble diffusion basin for ozone disinfection was not an option.

97. Conversion From Gas To Liquid Disinfection Yields Significant Improved Water Quality And Cost Savings 8/15/2018

    In 2006, the Greenwood, South Carolina Commissioners of Public Works became only the fourth U.S. water utility ever to receive Phase IV “Excellence in Water Treatment” recognition from the Partnership for Safe Water. Phase IV is the highest possible level of performance that can be achieved in the Partnership program and signifies optimized plant performance.

98. Evaluation And Optimization Of Clean-In-Place Using Ozone 8/15/2018

    A chemical company which specializes in Clean-In-Place (CIP) systems, contacted Mazzei to discuss the use of ozone as an alternative to peracetic acid sanitation or heat sterilization at their customers’ plants.

99. Case Study Report For Z-92® Uranium Removal – City Of Grand Island, NE 8/7/2018

    A single WRT Z-92® Uranium Removal treatment system was selected by the City of Grand Island, NE to remove high concentrations of uranium in three city wells.  When the Z-92® Uranium Removal treatment system was installed in 2012, it was the largest uranium treatment facility in the nation. The high uranium in the raw water source is consistently being reduced to levels below the Maximum Contaminant Level (MCL).
