Drinking Water Disinfection [Case Studies White Paper]

  1. Basin Nozzle Manifold Contacting System Installation Remediates Taste And Odor Compounds, Meets Disinfection Goals
    4/27/2017

    A water quality audit revealed that two of the largest drinking water plants in the City of Montreal were out of compliance with Quebec’s latest water quality rules. Both drinking water facilities were located in heavily populated areas; consequently, plant modifications had to be accomplished within their existing infrastructure footprints.

  2. A Rosemount Chlorine Analyzer Proves Just The Job For Seawater Duty At Dow's Terneuzen Site
    4/19/2010

    The Dow Benelux site in Terneuzen, the Netherlands, uses seawater for process cooling. Environmental regulations require careful control of the concentration of chlorine added to control microbial fouling. The existing chlorine measurement system had become outdated, so after stringent tests Dow decided to replace it with a Rosemount Model TCL analyzer from Emerson Process Management.

  3. Surface Water Treatment & LT2 Compliance - Surprise, Arizona (Case Study)
    3/12/2013

    The White Tanks Regional Water Treatment Facility (White Tanks) is located in Surprise, Arizona, and treats surface water from the Colorado River that is delivered by a 336 mile (540 kilometer) man-made canal.

  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. 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.

  6. Dissolved Air Flotation Technology Nearly Doubles Treatment Capacity
    3/21/2015

    Faced with a tight capital budget, a city in British Columbia required a new design for a water treatment plant capable of a maximum daily water production of 21 MPG during peak demand periods, with an ultimate demand of 29 MGD.

  7. ETS-UV™ Project Profile For Drinking Water In Berea, Ohio
    2/3/2017

    First settled in 1836, the City of Berea, Ohio gained acclaim as being the source for dimensioned stone formed from locally quarried sandstone, notably grindstones. The grindstones were shipped to Cleveland by oxcart and, as demand grew, later by a purpose-built railroad to the Big Four Railroad across the Midwest. Now many of the former quarry pits are better known as Baldwin Lake, Wallace Lake and Coe Lake.

  8. Water Works Commission Lowers Risk Profile By Converting To A Safer Disinfectant
    8/15/2016

    Chatsworth Water Works Commission provides both water and wastewater services to the 5,000 residents of the cities of Chatsworth and Eton, GA.

  9. 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?

  10. MIOX Achieves Increased Efficacy Against Biofilm And Legionella Vs. Common Biocides
    2/5/2014

    Comparative disinfection studies using 3 oxidizing biocides and 3 commonly used non-oxidizing biocides against Legionella pneumophilia.
