Wastewater Case Studies and Whitepapers

  1. Disinfection Performance Testing Of High-Efficiency Ultraviolet Water Treatment Chamber
    4/16/2014

    This is the second in a series of three white papers describing the design and performance of the NeoTech Aqua ReFlex™ treatment chamber. The first describes in detail the theoretical basis for the very high efficiency demonstrated by the chamber. The third paper describes how this chamber design leads to some highly desirable operational advantages beyond just energy ad cost reduction. By J. R. Cooper, Ph. D. and Gwynne Cavender, NeoTech Aqua Solutions, Inc.

  2. Florida County Partners With The WateReuse Association To Find The Best Use For Reclaimed Drinking Water
    2/14/2017

    In 2016 Hillsborough County Public Utilities, a forward thinking organization, initiated the first direct potable reuse pilot project in Florida. In its efforts to utilize 100 percent of its reclaimed water, the progressive utility created a successful program to effectively suspend surface water discharges. Read the full case study to learn more.

  3. Optimizing Gas Storage Fields Operation Through High Accuracy Multiphase Flow Metering
    8/6/2015

    Natural gas consumption is far from being constant over the months. Typically Natural Gas (NG) is stored in summer periods, when there is lower demand for it, and is withdrawn in the winter periods, when significant amounts of NG are used for heating.

  4. Money Down The Drain: The High Cost Of Poor Air Flow Metering
    3/14/2018

    Activated sludge systems have been a cornerstone of wastewater treatment for over 100 years. This biological process uses suspended growth microorganisms to break down and consume organics and remove nutrients from the wastewater. The heart of the process takes place in aeration basins, where the microorganisms need to receive sufficient oxygen to stay alive.

  5. How To Fix High pH And Comply With The Clean Water Act
    2/19/2014

    When the Clean Water Act was enacted, one of the intentions of this legislation was to reduce the untreated industrial waste water burden on publically owned waste water treatment plants (POTW) so that industrial wastewater would only load the treatment plant to the same extent as ordinary household sanitary waste. Industrial facilities that generated process wastewater had to begin pre-treatment of the water before it could be returned to the local POTW.

  6. KLa Slot Injector™ Aeration System Expands The Capacity Of An SBR At A Landfill Leachate Treatment Facility
    3/27/2013

    A landfill had an existing single basin SBR plant to process the leachate which is notable for its high nitrogen load. The original system was installed with a fine pore diffuser aeration system and due to the chemical/biological composition of the mixed liquor it was prone to diffuser fouling and premature membrane failure.

  7. UV Small Footprint And Flexible Hydraulics Makes Space For The Future
    5/16/2017

    When a piece of process equipment needs to be replaced, it is tempting to go with a straight replacement in kind – same manufacturer, same model, just the latest version of “the same”. But often, full consideration of other options opens new possibilities for your treatment plant. That was certainly the case for Plainfield, Indiana.

  8. Royal Environmental Systems And Water Tectonics Design State-Of-The-Art Stormwater Treatment System
    2/14/2008
    Located 20 miles east of Seattle,Washington, Redmond is home to 50,000 residents and many high-tech and biomedical companies, including Microsoft. Redmond’s downtown drainage area is dominated by commercial, industrial and roadway areas, with typical surface pavement contaminants such as metals, nutrients and sediments
  9. Key Indicators Of Tube Settler Strength: Module Design And Construction
    12/19/2017

    There is a common misconception about tube settlers that thicker material, whether it’s thermoformed or extruded, yields a stronger, more structurally capable module. On the surface, this seems like a reasonable assumption. However, when we look at the details of module design and construction, we see that this is not always true.

  10. Produce Potable And Pharmaceutical Grade Water From Problematic Brackish Water
    7/15/2014

    A pharmaceutical manufacturing plant located in Sedom, Israel faced challenging environmental conditions including low humidity, temperatures exceeding 105 degrees Fahrenheit and limited water supplies.
