Technology Strengths, Weaknesses and Critical Indicators

Evaporation Technologies:

  • Use heat to produce either manure with less water or dried manure solids
  • Reduce water in manure using a series of evaporators or recompressed process generated steam to evaporate water from liquid slurries—energy is supplied either by purchased fuel and/or waste heat from other processes
  • Systems that dry separated solids use either a belt or drum to evaporate water from separated solids—energy is supplied either by purchased fuel, electricity and/or waste heat from other processes
  • Compounds are released as the water is driven off (i.e. ammonia, hydrogen sulfide), this often requires additional treatment such as condensation of the water and/or scrubbing of the chemicals
  • Requires purchased energy and costs are a significant concern leading to a trade-off between input costs and gains in liquid concentration and transportation/market of by-products
  • Proven technology for nitrogen recovery, phosphorous recovery, storage reduction, GHG reduction, odor control and pathogen reduction

Newtrient Comments/Opinions:

Evaporation and Drying Technologies:

  • Uses heat to produce either manure with less water or dried manure solids
  • Systems that reduce water in manure use a series of evaporators to sequentially evaporate water from liquid slurries—energy is supplied either by purchased fuel and/or waste heat from other processes
  • Systems that dry separated solids use either a belt or drum to evaporate water from separated solids—energy is supplied either by purchased fuel, electricity and/or waste heat from other processes
  • Chemicals are released with the water (i.e. ammonia, hydrogen sulfide), and this often requires additional treatment such as condensation of the water and/or scrubbing of the chemicals
  • The requirement for purchased energy and costs are a significant concern leading to a tradeoff between input costs and gains in liquid concentration and transportation/market of by-products
