Drinking Water Disinfection Resources

81. Product Recovery Through Ozone Oxidation Of Waste Liquor 9/15/2018

    The manufacturing of soda ash from Trona is a multi-step process that results in the production of a waste liquor that contains significant levels of organic contamination.

82. Wastewater Plant In Como, Italy, Upgrades To De Nora Ozone For Significant Savings 9/13/2018

    The Lariana Depur wastewater treatment plant in Fino Mornasco, Italy, treats wastewater from multiple textile manufacturers in the Como region, known as the heart of the textile industry. Since 1994, ozone has been used effectively as a polisher to remove the dark blue-purple color — the result of the dyes used in the textile dyeing and printing process — from the water.

83. Groundwater Treatment Pilot Test Program Proves Successful In California (Loprest) 9/12/2018

    Iron, manganese, arsenic and hydrogen sulfide are indigenous to numerous groundwater aquifers. With the exception of arsenic, these constituents are more prevalent in deeper aquifers that are devoid of dissolved oxygen. This report summarizes the results and conclusions of a groundwater treatment pilot test program. 

84. EPA Researchers Partner With WaterStep To Deliver Clean Water During Emergencies 9/11/2018

    Following a disaster like the back-to-back hurricanes that hit Texas, Florida, and Puerto Rico in 2017, water systems can become flooded and unable to provide safe drinking water to communities. EPA researchers recognized the need for portable water treatment systems that can quickly and cost-effectively provide safe drinking water to affected communities following a disaster. 

85. Expansion And Upgrade Of WWTP Ozone Disinfection System Reduces Energy Cost By 69% 9/10/2018

    The financial cost to maintain their ozone equipment, and increasing scarcity of replacement parts for their ozone generator, motivated a utility in Springfield, MO, to upgrade their ozone system. Read the full case study to learn how the plant assessed the energy cost of a sidestream ozone injection system compared to that of a turbine mixing design and showed that the Mazzei retrofit design reduced the energy cost of ozone contacting by an average of 69.2% under all plant flow conditions.

86. Largest Ozone Facility In North America Meets Regulatory Requirements And Remediates Taste & Odor Problems 9/5/2018

    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).

87. 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.

88. 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.

89. 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.

90. 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.
