Drinking Water Treatment Case Studies and White Papers

  1. Aquatech Supplies Zero Liquid Discharge System In Puerto Rico Due To Environmental Regulations

    AES Puerto Rico Cogeneration Plant (AESPR) is a cogeneration power plant that produces 454 MW of net electricity in its fluidized bed boiler plant in Guayama, which is sold to the Puerto Rico Electric Power Authority (PREPA).

  2. Burnsville Becomes First Metro System With On‐Site Hypochlorite Generation

    When Linda Mullen took over as water superintendent in Burnsville in 2007, the city was in the process of adding surface‐water treatment to its existing plant. Burnsville began purchasing water from the nearby Kraemer Mining and Materials quarry, both to supplement its supply and to help the quarry meet discharge permits.

  3. City Solves Reliability And Maintenance Problems For WTP Hypo Feeds

    A municipal water quality manager reports replacement of sodium hypochlorite (hypo) vacuum feeder units with a more advanced type at one water treatment plant (WTP) has helped allow for continued reliability for chlorination.

  4. Case Study: Ambitious Water Quality Study Could Guide Development For Years
    The City of Kissimmee, Fla., has embarked on an ambitious water quality study that could provide a road map for development in the fast-growing tourist mecca – and save millions of dollars as the city begins to comply with water quality regulations
  5. A New Breakthrough In Flow Metering

    Municipalities that are looking to accurately measure their water flow rates often fall into one of three categories. By Mark Gimson

  6. White Paper: Understanding Differences Of Boiler Feedwater Pretreatment Equipment

    As a water treatment professional, there are several reasons for understanding the various types of boiler pretreatment equipment. It is helpful to grasp all selection criteria for the type of pretreatment. These factors are used for deciding what new equipment to install or why the existing equipment is appropriate or not appropriate. By Dave Christophersen, Veolia Water Technologies

  7. Factors Affecting Treatment Of Iron, Manganese And Hydrogen Sulfide With Chlorination And Manganese Dioxide

    There are different treatment processes used to remove iron and manganese from groundwater for potable water supplies.  While there are various less commonly used treatment methods available (such as ion exchange), most treatment systems for iron and manganese oxidize the ferrous soluble state of iron to a ferric state so the solid particles can then be filtered out.  

  8. UV Disinfection Eliminates Groundwater-Borne Pathogens At Water Utility

    A study led by the Marshfield Clinic Research Foundation set out to prove the growing evidence 'that our groundwater is fairly heavily contaminated with human pathogenic viruses.'

  9. Chicago Suburb Ensures Highest Water Quality Year-Round, Saves On Labor And Reagents With New Chlorine Analyzers

    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.

  10. Rural Water Plant Finds Leak With Clamp-On Flowmeter

    A rural water treatment plant in the Southwestern U.S. treats, stores, and distributes 325,00 gallons per day of water to the village it serves. The village consumes an average of 125,000 gallons a day and can store up to 1 million gallons. Unfortunately, the treatment plant was also losing 210,000 gallons a day due to an unknown leak.
