Drinking Water Case Studies and White Papers

  1. “Eureka!” Nevada Community Rushes To Meet U.S. EPA Arsenic Level Standard
    4/13/2017

    With the United States Environmental Protection Agency (USEPA) now requiring arsenic levels of 10 ppb for drinking water, reducing high levels of arsenic in one of its community’s water supply had been a challenge for Eureka County. Find out how a community, who once searched for silver, hunted down a way to remove high levels of arsenic from its drinking water.

  2. Change To 3-Precursor Vacuum Generator-Feeder For ClO2 In WTP, From Batch Generator Pumping, Cuts Chemical Costs, Gains Plant Management Of Equipment
    1/22/2018

    The water treatment plants (WTP’s) manager for the city of Midlothian, TX reports significant reduction in chemical costs, gaining new management control for their generation and feed equipment, and ending a pesky maintenance burden, by switching to three-precursor vacuum generator-feed, from batch-generator-pumping, for introducing chlorine dioxide (ClO2) into their 8 MGD plant #2. As a result, he plans to make the same change at their 12 MGD plant #1.

  3. Mitigating Environmental Impact Of Gold Mine’s Wastewater Through Ozone Oxidation And Aquifer Re-injection
    4/27/2017

    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.

  4. Performance Of A Conventional Surface Water Plant Using Mixed-Oxidants For Microflocculation And Final Disinfection
    1/20/2009

    The surface water source is from snow-melt and summer thunderstorm run-off from the mountains. This water is detained in McClure Reservoir (7876 ft elevation) and Nichols Reservoir (7483 ft elevation) upstream from the CRWTP, a conventional plant built in 1974 with a design capacity of 8 MGD. Because the City has limited surface water rights, and due to decreased demand, the treatment plant usually shuts down for 60 to 90 days during winter. The reservoirs thaw in spring and turn over in autumn, and during the summer rainy season, raw water turbidities may exceed 5 NTU. By MIOX Corporation

  5. City Of Punta Gorda Improves Distribution System Residuals By Installing The Tank Shark® Mixing System In Two Million Gallon Punta Gorda Isles Reservoir
    7/10/2018

    Historic Punta Gorda, located on the shores of scenic Charlotte Harbor on the west coast of Florida prides itself in the proactive management of its water supply. With the responsibility of providing water to over 34,000 customers in the 38 square mile service area, Punta Gorda manages 237 miles of distribution pipe and two water storage facilities. The 1 million gallon (MG) Burnt Store elevated tank and the 2 MG Punta Gorda Isles ground storage tank provide distribution system balance as well as the ability to meet peak demands and fire protection capacity.

  6. Top 10 Reasons To Choose A Diaphragm Actuated Control Valve
    7/23/2014

    Every water system typically consists of piping networks that distribute water from a source or storage reservoir to the end users. This usually will require some form of a valve that will have to be controlled.  

  7. Membrane Module Pilot Test In North Dakota
    10/11/2017

    Toray UF membrane modules were piloted over a fifteen-week period to help service the growing demand for clean water in southwest North Dakota. The outcome, as part of the Southwest Pipeline Project (SWPP), would be construction of the Oliver-Mercer-North Dunn (OMND) Water Treatment Plant.

  8. Transient And Surge Related Pipe Bursts, Water Loss And Damage Prevention
    2/13/2013

    Pipe bursts as a result of transients and surges within a piping network are very common problems throughout the world. Not only are the maintenance costs of these repairs extremely expensive, but when you add in possible litigation for third party damages, combined with the potentially significant value (cost) of the lost water, you can quickly realize the significance of what may appear simply as “another pipe burst”. By Brad Clarke, Singer Valve Inc.

  9. Bringing An END™ To RO Brine And Difficult Brackish Water Treatment
    6/8/2018

    Access to clean, safe, fresh water is one of the greatest challenges facing humanity in the 21st century. By some estimates over 1.5 billion people face water scarcity issues that directly threaten their health or economic welfare on a daily basis. More concerning, the impacts of climate change and global population growth are expected to exacerbate these issues to impact over 2.3 billion people by the year 2050. These sobering facts are why six of the United Nations (UN) Sustainable Development Goals (SDGs) are focused on providing access to clean, safe water. Part of solving this challenge is reducing industrial water consumption to conserve water resources.

  10. Ozone-On-Demand™ Reduces Water Treatment Cost By 20%
    11/15/2012

    Pinnacle Ozone Solutions’ new generation of smart Ozone-On-Demand (OOD™) generator and control technology can help significantly reduce the cost and complexity of ozone water treatment.
