Sludge & Biosolids Processing Studies & White Papers

  1. Sewer District Reduces Plant Polymer Usage With PolyBlend® DP Dry Polymer Preparation System
    8/10/2016

    Located between San Francisco and Sacramento in Solano County, California, the Fairfield-Suisun Sewer District (FSSD) services more than 135,000 residential, commercial and industrial customers over 41 square miles.

  2. PolyBlend M-Series Liquid Polymer Wetting And Activation System
    8/10/2016

    The 1.5 MGD West Carrollton Wastewater Treatment Plant in West Carrollton, OH came on-line in 1989 and today serves 12,000 area residents. The activated sludge facility produces an average of 200 wet tons/month of sludge that, following belt filter press dewatering, is spread on area farmland by a biosolids management company.

  3. City Of Tacoma, WA, Continues To Choose PolyBlend® Dry Polymer Preparation Systems After 25 Years Of Reliable, Consistent Performance
    8/10/2016

    Serving over 200,000 ratepayers, the City of Tacoma operates two award-winning wastewater treatment plants.

  4. City Of Dartmouth Reduces Polymer Usage And Improves Dry Solids With PolyBlend® Polymer Preparation Systems
    8/10/2016

    The City of Dartmouth, MA, Water Pollution Control Division is responsible for operating the town’s 3 million gallon per day wastewater treatment facility, a testing laboratory, a composting site, a sludge.

  5. Tooele, UT, Harnesses The Sun To Reduce Sludge Volume And Saves Big
    7/8/2016

    City of Tooele needed to reduce sludge volume that would produce reusable material, be simple to maintain, and provide cost effective operation. The Huber Technology SRT Solar Dryer was determined to be a technology fit to achieve Tooele’s goals. The linear feed design of the SRT Solar Dryer provided the ability to feed dewatered sludge to the dryer as it was produced. Read the full case study to learn more about their installation.

  6. Time-Tested Technology: 25 Years of Trickling Filter Media Success
    6/13/2016

    The Bissell Point Wastewater Treatment Plant is the largest wastewater treatment facility in Missouri with an average flow rate of 123 MGD. In the mid-1980s, the facility expanded to provide secondary treatment. The goal of the upgrade was to select a reliable process that would achieve high-rate BOD removal.

  7. Innovative Use Of Dissolved Air Flotation With Biosorption As Primary Treatment To Approach Energy Neutrality In WWTP’s
    6/1/2016

    This paper presents two types of DAF applications together with biosorption (the “Captivator system”) as primary treatments. In one case, the Captivator system is the sole primary treatment for a new plant installation and helps to gain 65 percent more biogas while requiring only 44 percent of aeration for COD oxidation, compared to a conventional process.

  8. Precise Biogas Flow Measurement
    4/25/2016

    As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas.

  9. South Dearborn’s Experience With Multiple Dewatering Processes Led Them To Q-Press®
    4/6/2016

    Plant staff with experience operating belt filter press and centrifuge has decided on the use of the Huber Technology Q-Press®. The new technology helped them overcome the challenging dewatering situation brought on by their anaerobically digest sludge. Read about their journey and the lessons learned.

  10. Weighing And Remote Monitoring For Reliable Wastewater Treatment
    1/15/2016

    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!
