Technology Description:

Heliantis™ transforms any type of dewatered sludge (15% minimum dry content) into a dry, granulated product with a dry-solids content that can be adjusted within a range of 35% to 85%. Using the sun as the main energy source, the sludge is dried in a greenhouse and a scarifying machine turns over and breaks up the sludge into carbon-neutral and odorless granules, for eventual agricultural reuse or thermal energy production using co-incineration.

Technology Strengths,Weaknesses and Critical Indicators

Active Drying Technologies:

  • Produce a marketable product, dry manure solids, and reduce transportation costs
  • Require energy to reduce water content and dry manure solids, purchased energy cost are an issue
  • Require operator attention in excess of other systems due to the risk of combustion
  • Other compounds are released with the water (i.e. ammonia, hydrogen sulfide), and require additional treatment
  • Potential loss of ammonia nitrogen due to volatilization
  • Proven technology for storage reduction, odor control, GHG reduction 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
