Drinking Water Disinfection Resources

91. 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.

92. Robust Encore® Pumps Replace Peristaltic Hose Pumps To Maintain Consistent pH For Finished Drinking Water 8/22/2018

    Upper Deerfield Township, NJ relies on groundwater from four wells measuring 120 to 160 feet deep. The water is treated at two treatment plants with a capacity of 2.2 MGD and then pumped out to the distribution system with approximately 750,000 gallons of storage. Since the deep groundwater is hard, operators add lime to the finished water to raise the pH to reduce hardness.

93. 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.

94. 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.

95. 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). 

96. Cobb County Expands “Excellent Production Of Potable Water” With ClorTec® DN OSHG System 8/3/2018

    De Nora’s ClorTec® DN OSHG systems feature market-driven innovations including robust PVC/FRP casings with end view ports, remote monitoring and control, and simple operation and maintenance with 100% access to every component. Systems from 12-3,000 lbs/day produce a guaranteed .8% hypochlorite concentration and feature the DSA® bipolar electrodes pioneered by De Nora. Read about how one community expanded their “excellent production of potable water” with the new ClorTec® DN OSHG System.

97. Five Trends In The Water Purifier Market Worth Paying Attention To 7/25/2018

    According to a recent survey by the Water Quality Association, 30 percent of residential water utility customers are concerned about the quality of the water coming out of their taps, which is likely one reason that American consumers spent upwards of $16 billion on bottled water last year. It’s also why the water purifier market continues to experience extreme growth and is expected to garner $45.3 billion by 2022 as companies in the space look to better cater to consumer demand.

98. Australian City Installs Microclor On‐Site Sodium Hypochlorite Generation System 7/24/2018

    Bathurst is the home of the Bathurst 1000 Race, the largest NASCAR-style “touring car” race in Australia. On race day, tens of thousands of additional visitors tax the capacity of the Bathurst 5 million-gallon-per- day wastewater treatment plant. The diligence and capability of the treatment staff allows the plant to meet the challenge every year. 

99. City Of Austin, Texas Installs A Total of 4,500 Pounds‐Per‐Day Of On‐ Site Hypochlorite Capacity Using the Microclor® OSHG System 7/24/2018

    With 100 years of service history, Austin Water has seen enormous change in its 540 square miles of service area. Planning for the next 100 years has city and utility planners considering a diversity of sources, system resilience, and sustainability while being mindful of conservation goals. In the city’s newest water treatment plant, WTP4, Austin Water was able to combine those planning elements into a state‐of‐the‐art treatment plant. The plant, which is located on Lake Travis, is capable of treating 50 million gallons a day (MGD) with the ability to expand to 300 MGD.

100. Utility Removes Burdensome Bulk Sodium Hypochlorite From Operations 7/24/2018

     Historically, Lyon County Utilities, Nevada, applied 12.5% bulk sodium hypochlorite for disinfection at each of their well sites. Always looking to improve system efficiency, Lyon County staff reexamined on‐site hypochlorite generation to determine if the use of the 0.8% sodium hypochlorite solution could mitigate the challenges associated with dosing high strength sodium hypochlorite.
