Drinking Water Disinfection [Case Studies White Paper]

  1. Dissolved Air Flotation System Removes Algae And Manganese At Evitts Creek Plant
    3/16/2015

    The Evitts Creek Water Treatment Plant (WTP), owned and operated by the city of Cumberland, Maryland, provides potable water for Cumberland and surrounding communities in Maryland, West Virginia, and Pennsylvania.

  2. Monitoring Chlorine Residuals For RO Membranes - ORP Versus Chlorine Analyzers
    7/14/2015

    In processes where disinfection is required chlorine is the most common and economic disinfectant followed by sodium hypochlorite (liquid bleach). It is important to disinfect the RO feedwater to avoid fouling of the membranes which results in poor performance and frequent cleaning.

  3. 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.

  4. 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.

  5. The UV Uprising: How UV Disinfection Will Claw Its Way To Prominence
    6/20/2014

    Chlorination in all of its forms — gas, liquid, or solid — has been the primary way for treatment plants to disinfect the treated wastewater. The treatment plants that use gas chlorination must face federal regulatory oversight in the form of a Risk Management Program (RMP). Liquid chlorine plants trade in the regulatory oversight for a more expensive and less effective product. While chlorine in its solid form is good for small treatment facilities known as package plants (named for their mobility). However, ultraviolet (UV) technology is rapidly altering the landscape of disinfection throughout the industry.

  6. Engineering For Safe Chlorine Disinfection
    6/6/2011

    For more than 75 years chlorine has been effectively used to disinfect drinking water, eliminating dangerous bacteria and toxic compounds. Water supply engineers and treatment facility operators are used to necessary risks and problems associated with chlorine disinfection in order to deliver safe water. By Harland R. Pond, Product Manager; Grundfos

  7. Baja California, Mexico Addresses Water Scarcity, Partnering With Fluence
    11/12/2015

    When the government of Baja California, Mexico, declared a water emergency for the region of San Quintín in 2014, leaders knew they needed to find a solution to ensure residents a reliable, safe water source.

  8. Clari-DAF Pretreatment System Reduces Chemical Consumption, Doubles Treatment Capacity
    3/25/2015

    Together, two water treatment plants in Boulder, CO, have the capacity to treat 55 million gallons per day (MGD). When severe drought conditions restricted the source water supply of the Betasso WTP, the city decided to expand the capacity of the Boulder Reservoir Water Treatment Plant (WTP).

  9. Degas Separator Selected For Wichita Aquifer Storage And Recovery Project
    4/26/2017

    In the 1990s, the City of Wichita, KS, developed a water supply plan that included creating a sustainable water supply through the year 2050. The key component of the plan is recharging the large aquifer that lies under the region with 100 MGD of water from the Little Arkansas River.

  10. The Role Of UV In Solving Next-Generation Water Challenges
    7/4/2013

    The global market for water treatment technologies is growing and becoming increasingly important as the quality and quantity of freshwater sources are stressed and the link between fresh water sources and wastewater — returned to the environment — is more and more obvious. By Rick VanSant, President & CEO, UV Pure Technologies, Inc.
