Drinking Water Disinfection [Case Studies White Paper]

  1. Salt Lake City Public Utilities ‐ Award Winning Big Cottonwood WTP, Experiences Microclor® On‐Site Hypochlorite System Reliability and Safety For Over Six Years
    7/18/2018

    Located at the mouth of the Big Cottonwood Canyon, the Big Cottonwood WTP is one of three water treatment facilities providing treated water to Salt Lake City (SLC), Utah. The utility distributes water through about 1,300 miles of transmission and distribution pipe to over 90,500 connections. Recently, the Big Cottonwood WTP was recognized for delivering 16 years of high quality water and received the Directors Award from the EPA & AWWA Partnership for Safe Water.

  2. 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. 

  3. Is Coagulation Followed By Filtration Viable To Remove Arsenic When Raw Water Arsenic Levels Are High?
    10/9/2018

    The objective of the pilot study was to demonstrate “proof of concept” if coagulation followed by filtration was a viable technology to remove arsenic in water from Well No. 6 when raw water arsenic levels are so high, >70 ppb. Preparations were made to reduce the pH of the raw water if it was required. Also, two unique arsenic adsorptive medias were evaluated as a final polishing step to the effluent of the coagulation/filtration process.

  4. 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.

  5. Coming Of Age: UV-C LED Technology Update
    7/2/2015

    Sometimes technology innovations come along which cause a paradigm shift in how products are designed.

  6. 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.

  7. 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.

  8. Encore® 700 Chemical Metering Pumps Provide SNWA With A Decade Of Flawless Service At River Mountains
    8/15/2016

    Built in 2002, Southern Nevada Water Authority’s (SNWA) River Mountains Water Treatment Facility is a state-of-the art  water treatment facility that delivers 300 million gallons per day and was designed to be expanded to deliver up to 600 million gallons per day of treated water in the future.

  9. Drinking Water Disinfection: Tianjin, China (Case Study)
    1/31/2013

    Favorable reviews of UV technology in wastewater applications influenced Tianjin Economic Development Area (TEDA) Water Supply General Company to investigate the potential of using UV for drinking water applications at one of its water treatment plants. With no previous UV installations for drinking water disinfection in the country, TEDA's process of selecting a UV manufacturer was stringent. We are honored that they chose us and our TrojanUVSwift™ system.

  10. Clarification And Filtration Upgrades Using ACTIFLO Technology
    1/12/2017

    The City of Somersworth has a historical background dating back to the early 1900s when it became the first community to start using chlorine to disinfect it’s drinking water.
