Wastewater Contaminant Removal White Papers & Case Studies

  1. Mapping And Identifying The Source Of Water Quality Issues
    6/28/2017

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  2. Has The Ideal Biocarrier Finally Been Developed?
    6/1/2017

    In order to improve the efficiency of biofilm technologies, a high-performance biocarrier has been developed, based on requests for ideal carrier characteristics.

  3. Filter Technology Saves Colorado Plant 50,000 GPD
    5/16/2017

    Combined with the installation of the new filter media and wash troughs, this particular type of underdrain and media retainer brought the water treatment plant’s operations up to speed.

  4. Improving The Quality Of Secondary Wastewater For Indirect Potable Reuse—From Pilot To Full Scale Plant
    5/15/2017

    In spite of the recent abundance of water, many of California’s aquifers continue to balance on the edge of water scarcity. Decades of overpumping have reduced the amount of ground water available to supplement surface water resources diminished by drought. The Pure Water Monterey Ground Water Replenishment Project (Monterey Pure), addressed the need to replenish a local aquifer, by piloting Advanced Water Treatment (AWT) processes, to determine the best method to convert secondary wastewater into a pure water resource.

  5. Pure Oxygen Injection Into A Pipeline
    5/4/2017

    The Hagerstown Wastewater Treatment Plant in Maryland incorporated several plant modifications, one of which was the conversion of their disinfection process from the use of ozone to UV.

  6. Retrofit Significantly Reduces Backwash Cycle Interval, Duration And Water Use For Georgia Utility
    5/1/2017

    The North Columbus Resource Facility recently completed a $12-million replacement of its settled water filtration, removing the existing Wheeler filters, their three-part media and 10-inch poured concrete underdrains, which were no longer efficient.

  7. Mitigating Environmental Impact Of Gold Mine’s Wastewater Through Ozone Oxidation And Aquifer Re-injection
    4/27/2017

    Installing and operating an ozone oxidation system for wastewater remediation at a gold mine located in a remote region of Alaska is full of challenges.

  8. Center Feed Drum Screen Is Mission Critical To World Class MBR Plant
    4/25/2017

    North Las Vegas has installed some of the largest rotary fine screens operating in the United States. The center feed drum screens are critical to protecting the membrane bioreactor, enabling the plant to maintain extremely low turbidity coming off their plant that is better than most potable water. Read how they are putting the ROTAMAT RPPS to work.

  9. Compact Footprint And Flexible Hydraulics Ease Initial Expansion, Leave Room For Future Growth
    4/11/2017

    When Plainfield, IN, needed to double their permitted capacity from 2 MGD to 4 MGD at their South wastewater treatment plant, they faced a dilemma. Like most treatment plants, space is at a premium, and compact design was needed not only for the current expansion, including the addition of a post aeration structure, but to preserve as much room as possible for projected future expansions.

  10. Significant Energy Saving Resulting From Change Of Thickening Technology
    4/7/2017

    During the summer of 2015 the Waging WWTP in the Bavarian Chiemgau district was desperately looking for an energy-efficient, high-performance sludge thickening plant to replace the centrifuge they had been using. The objective was to optimize digester capacity, gas yield and sludge handling in the overall process on site. Read more about their successful implementation.
