    1/21/2015

    The Ventura Regional Sanitation District’s Liquid Waste Treatment Facility (LWTF) was experiencing a double-threat to safety and productivity.

  3. San Diego Experiences Benefits Beyond Contaminant Reduction
    12/25/2014

    Because inadequate screening was allowing hair, fiber and sand contaminants to work their way through its treatment process, The City of San Diego Public Utilities Department Wastewater Branch sought out sludge cleaning technology that they could integrate into their existing system.

  4. Center Feed Drum Screen Is Mission Critical To MBR Plant
    12/23/2014

    Huber’s center-feed drum screen was recommended as the best technology to prevent wash around that can ruin the membrane bioreactor at a WWTP in Las Vegas.

  5. CleanFlo™ Monoscreen® Case Study
    12/22/2014

    When the polar bears at the Brookfield Zoo were introduced to their new habitats at the Great Bear Wilderness, they had no idea how much more fulfilling their life would become.

  6. Sturbridge POTW: Greater Capacity For High Flow Events, Enhanced Clarification For New Regulations
    12/16/2014

    Sturbridge, Massachusetts historically suffered from periodic blooms of filamentous bacteria that caused bulking in the secondary clarifiers of their three activated sludge package plants.

  7. Concord, Massachusetts WWTP - A Low-Cost, 20-Year Solution To Ever-Tightening Phosphorus Limits
    12/16/2014

    Prior to 2007, Concord, Massachusetts wastewater treatment plant operated under a NPDES permit that allowed a seasonal phosphorus limit of 0.7 mg/L. But with the issuance of a new five-year permit with a phosphorus limit of 0.2 mg/L and the probability that future limits could reach as low as 0.05 mg/L, Concord needed a treatment solution that would be reliable and cost-effective today and over the long term.

  8. A New Paradigm In Aeration Technology
    5/13/2014

    The DO2E organization sprang from one individual’s attempt to solve an aeration problem in a fish hatchery and realizing that his device to do so had many other applications as well. This device broke up algal blooms as well as aerating, and it was only a short step to modify it into breaking up FOG (fats, oils, and grease) deposits in grease traps and lift stations. This device was patented, thus DO2E was born.

  9. Pump Station Bar Screen Saves City $26,000 In Labor
    4/15/2014

    New Jersey’s Lower Township Municipal Utilities Authority had a problem. The utilities authority operates a 5 MGD plant, with wastewater inflow arriving through a 48-in pipe routed 23 feet below grade level. Their manual inflow pump screening setup was difficult and hazardous to clean, and its 2.5” screen spacing let entirely too much non-dispersible waste through. Their 3,000 GPM non-clog pumps were constantly clogging, and workers were repeatedly exposed to a hazardous situation.

  10. Clarification System Boosts Capacity, Reduces Maintenance
    2/3/2014

    Spikes in peak demand at the 3.0 MGD Freedom District Water Treatment Plant in Carroll County, MD, exceeded 70 percent of the plant’s capacity, and the existing clarifier made for a lengthy sludge-removal process. After staff installed a dissolved air flotation (DAF) pretreatment system to improve the efficiency of the membrane filters, the now 4.0 MGD facility has reduced maintenance for operators. The system also safeguards against pathogens that can pass through traditional sand/diatomaceous (S/D) filters.
