Drinking Water Disinfection [Case Studies White Paper]

  1. Reservoir Overcomes Toxic Algae Issue
    6/16/2015

    A Nebraska reservoir was experiencing toxic algae in its water. Constructed by the U.S. Army Corps of Engineers (COE) primarily as a flood control reservoir with recreation and irrigation as secondary uses, the reservoir has a surface area of 700+ acres with an average depth of almost 12 feet.

  2. Ion Exchange: A Viable Water Treatment Alternative To Membranes
    10/8/2014

    Five decades ago, ion exchange using charged resins was one of two processes used in the water industry for water treatment.

  3. Chicago Suburb Ensures Highest Water Quality Year-Round, Saves On Labor And Reagents With New Chlorine Analyzers
    5/18/2015

    For the Village of Lombard’s Water Division, consistently delivering high-quality tap water to the community’s nearly 44,000 residents and the businesses serving them was once quite a juggling act: constantly fixing old, temperamental analyzers; feeding reagents into the old analyzers; and staying ahead of callers complaining about “musty” water tastes and odors. Not today.

  4. Indirect Potable Reuse With UV-Oxidation - Big Spring, Texas (Case Study)
    12/12/2016

    In an effort to reduce reliance on dwindling surface and groundwater supplies in Texas, the Colorado River Municipal Water District (CRMWD) constructed a new Raw Water Production Facility (RWPF) in Big Spring. Big Spring is a 27,000-member community located in West Texas approximately 300 miles west of Dallas. This RWPF treats secondary wastewater to a standard that allows it to be re-introduced directly into the raw water supply for the water treatment plants of Big Spring, Odessa, and other communities in the region.

  5. Ozone Disinfection System Provides Second Stage Treatment For Water Treatment Plant
    6/19/2015

    Tampa Bay Water’s state-of-the-art surface water treatment plant has provided high-quality drinking water to the Tampa Bay region.

  6. Dissolved Air Flotation System Reduces Costs, Improves Process
    3/1/2015

    With the town of Johnstown, CO's, water treatment plant began operating its circular clarifier systems at maximum capacity to meet summer peak demand rates, consultants recommeded increasing plant capacity and using dissolved air flotation technology for their clarification process.

  7. 4-Log Virus Inactivation - Abington, Pennsylvania (Case Study)
    6/2/2014

    The Hall Road Well Station — located in Abington, Pennsylvania — is designed to extract and treat 1.5 million gallons per day (MGD) of water from the Piedmont and Blue Ridge crystalline-rock aquifers. It is part of a network of groundwater extraction wells owned and operated by Aqua-America Pennsylvania (Aqua PA). Aqua PA determined that UV technology was the best approach for meeting the Pennsylvania Department of Environmental Protection regulations for 4-log virus treatment of groundwater. This case study will show you why they chose the TrojanUVSwift™SC.

  8. The Age Of Peracetic Acid — A Solution To Increasingly Challenging Regulations
    2/1/2016

    While chlorination has long dominated water disinfection, new approaches and technologies have emerged in the wake of disinfection byproduct (DBP) regulations. Could peracetic acid (PAA) be the option that dethrones the king?

  9. UV Disinfection In The Developing World
    1/19/2011

    Clean water is essential for life. Nearly one billion people around the world lack access to safe water and approximately 3.5 million deaths each year are linked to waterrelated diseases. By Real Tech

  10. Using Ozone To Remove Micropollutants From Wastewater
    12/1/2014

    Micropollutants in our wastewater are a growing problem and so is the concern for the long-term hazard to the ecosystem.
