Sludge & Biosolids Processing Studies & White Papers

  1. Durango Wastewater Treatment Plant Foils Energy Heist And Lowers Maintenance Costs
    8/8/2015

    The Durango wastewater treatment facility is a traditional waste-activated system. The bio-solids (WAS) is collected from secondary clarifiers, treated with flocculants and thickened before an anaerobic digestion. A centrifuge had been used for the thickening process which dewatered the WAS to a 8 to 10% consistency. The plant had three 50 hp units and used either one or two of the units as needed

  2. Monsters Protect Pump Station, Weather Storms In Scotland
    7/14/2015

    Pump blockages and rags are a significant barrier to energy and operational efficiencies at pump stations, causing unscheduled shut downs, safety hazards for operators, costly equipment repairs and increased power usage due to a decrease in the pumps’ hydraulic performance. Scottish Water observed these negative effects caused by an influx of wipes and rags throughout a network of area pump stations. Engineers looked to a proven, powerful solution in the form of two JWC Environmental Channel Monster® grinders at one of their most problematic sites.

  3. Pumps Reduce Costs, Improve Reliability, And Deliver Outstanding Energy Efficiency For Ohio WWTP
    7/8/2015

    An aging lift station in Marietta, OH, was the first of 12 stations to be upgraded as part of a capital improvement plan at the city’s wastewater treatment plant (WWTP).

  4. Macerator Explodes, Monster Sludge Grinder Takes Over
    6/30/2015

    The Coeur D’Alene, ID, wastewater treatment plant was having continual problems with two sludge macerators, in part because of the durability of the macerator.

  5. 10K Muffin Monster Takes Over When Macerators Can’t Cut It
    6/3/2015

    The Cibolo Creek Municipal Authority (CCMA) provides regional wastewater services for the area northeast of San Antonio, Texas and serves the surrounding communities. After years of frustration in dealing with severe problems with plugging of the pump suction lines that led to frequent pump rebuilds, they turned to the 10K Muffin Monster. The 10K Muffin Monster now plays an integral role in this water reclamation plant’s system by grinding the primary sludge and debris that is pumped to the digesters.

  6. Upgrade Of Channel Monster Cuts Wipes Problem And $78k From Electrical Bill
    6/3/2015

    Keeping up with both the water needs and sewage disposal of the Santa Margarita Water District has come with significant challenges, particularly due to both the increase in influent and change in the makeup and durability of the sewage running through the district’s reclaimed-water facility.

  7. Activating The Sludge In Small Municipal Facultative Waste Lagoon Systems
    6/2/2015

    Wastewater treatment lagoons were originally facultative in design — shallow, single and multi-cell lagoon systems that counted on wind, sunlight, anaerobic bacteria, and time for the digestion of the organic components of the wastewater.

  8. Submersible Aerators Blast Off At Naval Air Station WWTP
    3/30/2015

    When the Jacksonville, Florida Naval Air Station needed to increase oxygen in their aeration basins, they turned to Fluence. Five submersible HURRICANE aerators provide bottom-up mixing, drawing surface air and dispersing it in a 360-degree pattern near the basin floor. Long bubble hang time results in excellent oxygen transfer, and ensures excellent BOD and ammonia removal, treating flows up to 3 MGD.

  9. BioCon®: A Class A Solution
    3/17/2015

    The Picnic Point Wastewater Treatment Facility was faced with reaching their plant processing capacity. The plant was sending its biosolids to be incinerated and part of this challenge was to find a way to manage the biosolids produced by this facility. Hauling and disposing of this sludge was difficult and becoming expensive. It was desirable to have a Class A biosolid to alleviate this concern and be more environmentally conscious.

  10. North Carolina Treatment Plant Eliminates Taste And Odor Issues With Ozonation
    3/9/2015

    Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant-Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), Cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public.
