Drinking Water Disinfection [Case Studies White Paper]

  1. Theoretical Operation Of High-Efficiency Ultraviolet Water Treatment Chamber
    4/16/2014

    The NeoTech Aqua ReFleX™ water purification chambers are the most efficient and compact units available today. They require an order of magnitude less energy and less than 25% of the system volume to achieve the same or better purification result as competing chambers. This is the first in a series of three white papers explaining the benefits of these systems. By J. R. Cooper, Ph.D, NeoTech Aqua Solutions, Inc.

  2. EPA Researchers Partner With WaterStep To Deliver Clean Water During Emergencies
    9/11/2018

    Following a disaster like the back-to-back hurricanes that hit Texas, Florida, and Puerto Rico in 2017, water systems can become flooded and unable to provide safe drinking water to communities. EPA researchers recognized the need for portable water treatment systems that can quickly and cost-effectively provide safe drinking water to affected communities following a disaster. 

  3. Water Treatment Plant Solves Taste And Odor Problems And High Toxin Levels
    3/20/2015

    Phoenix is one of the country’s fastest growing metropolitan areas and has one of the most arid desert climates. Population growth coupled with increasingly stringent water regulations pushed the city to proactively address future water supply concerns. The decision was made to build the Lake Pleasant Water Treatment Plant (WTP) and include oxidation and disinfection treatment barriers.

  4. 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.

  5. A New Way To Kill Legionella
    1/10/2019

    Advanced oxidation provides an all-in-one solution that supports the complete eradication of Legionella in a water system, while also preventing its regrowth.

  6. Need More Water? Think Ozone-BAC For 'One Water' Resolution
    8/25/2017

    If you thought reverse osmosis was the one and only choice for potable water reuse, think again. Ozonation followed by biological activated carbon (ozone-BAC) is more suited to inland communities and may be better at removing chemicals of emerging concern (CECs).

  7. Ozone To Enhance Removal Of Iron And Manganese And Reduction Of THM
    8/15/2001

    The U.S. EPA's promulgation of the Stage 2 Disinfection By-Products Rule required  the Public Works Department of Danvers, MA, to establish a Two-Phase upgrade of the plant’s treatment process in order to comply.

  8. Ozone-Biologically Active Filtration For Potable Reuse In California's Inland Communities: Benefits And Barriers
    5/17/2016

    California’s inland communities have been hit hard by four years of drought, lower groundwater levels, and reduced allocations from the State Water Project.

  9. 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.

  10. Monoclor Chloramine Residual Management System Manages Residual For Problematic 5.5 Million Gallon Tank
    7/10/2018

    Eastern Municipal Water District (EMWD) serves about 142,000 customers in Riverside County, CA. The EMWD service area is one of the largest for any water district in arid southern California. On the drinking water side, EMWD manages two water treatment plants and over 15 reservoirs. With 70% of the district’s water coming from the Metropolitan Water District with chloramine disinfection, EMWD has become reliant on chloramine disinfection to manage long transmission lines and longer detention times.
