  • Class B Biosolids with Land Application
  • Unison 570 scfm Biogas Conditioning System for (2) GE Jenbacher IC  1,060-kW combined heat and power (CHP) cogeneration units, biogas/natural gas fired boilers
  • At peak production, the generator is expected to produce enough electricity to supply half of the power needs of the entire treatment plant, reducing the county’s carbon footprint by 9700 metric tons per year and saving ratepayers $500,000 annually in utility costs.

  • Unision biogas conditioning dubuqueCombined heat and power, biosolids reuse, effluent heat recovery
  • Biogas recovery and improved biosolids handling by converting from fluidized bed incineration to temperature-phase anaerobic digestion.
  • 10 mgd plant was completed in May 2014 with Strand Engineers and IIW Engineers.
  • Anaerobic digestion enabled the facility to harness biogas for digester heating and electricity generation using Unison Solutions, Inc equipment.
  • Saves approximately $250,000 a year
  • Added septage receiving station to increase biogas
  • Previously Biosolids were incinerated, now approx 5 tons/d Class A biosolids to fertilize corn and soybean fields
