Sludge & Biosolids Processing Studies & White Papers

  1. Weighing And Remote Monitoring For Reliable Wastewater Treatment

    Wastewater treatment can be a dirty job — but someone has to do it. At a Canadian wastewater treatment plant (WWTP) serving around 75,000 citizens, between 240 and 300 cubic meters of digested sludge are treated each and every day!

  2. Valuable Lessons Learned With Unknown Septage

    When SAWS in San Antonio sought to upgrade their septage collection system they faced challenges beyond what might be normally seen in a typical WWTP. By partnering with Huber Technology SAWS was able to navigate through challenges and put together a world class system.

  3. Sonoma County Improves Sludge Handling With Screw Press Pump Technology

    When California’s Sonoma County Water Agency (SCWA) wanted to improve its sludge solids dewatering as part of a major sludge handling upgrade, they were seeking an alternative to outdated sludge belt press/conveyor technology.

  4. Packaged Wastewater Treatment Plant Meets Tricky Challenge

    Packaged Wastewater Treatment Plants offer many advantages, flexibility notwithstanding. One plant in particular, located in Georgia, needed to be upgraded to handle the increased flows from a growing city and to address new effluent discharge regulations.  The tight plant site offered minimal opportunity for routine expansion of the packaged wastewater plant volumes, hence special designs were needed. Learn how this 200,000 GPD system is thriving.

  5. Outfitting The World’s Largest And Greenest Wastewater Treatment Plant

    The sprawling Blue Plains Wastewater Treatment Facility is the largest advanced wastewater treatment plant in the world, with a capacity to treat an average of 370 million gallons of sewage a day.

  6. Dry Pit Submersibles Lower Costs And Eliminate Unscheduled Maintenance

    A utilities department was experiencing frequent unscheduled maintenance visits and corresponding unbudgeted repair bills for the pumps at the township’s main pump station.

  7. 99 Percent Efficient Plant Shows How To Recycle And Profit

    An outstandingly efficient industrial wastewater treatment plant using technology being introduced to Australasia is demonstrating to the food, beverage, and agribusiness processing industries how to turn waste into profit.

  8. Pump Station’s Non-Dispersibles Problem: Solved

    Sun City, AZ, has had the same wastewater treatment plant since the '70s, along with a new, expensive problem: non-dispersible waste.

  9. RTC‐ST Reduces Polymer And Increases Biogas Production

    Hach’s off‐the‐shelf Real-Time Control System for Sludge Thickening (RTC‐ST) adjusts the sludge thickening process in real time. Thanks to the RTC-ST, a wastewater treatment plant improved thickened sludge consistency and gas production while reducing money spent on excessive polymer dosing and maintenance.

  10. Waste Technologies Transform Problems To Profit

    Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.
