Komline Sanderson – Drying System

Company Description:

Komline-Sanderson develops, designs, and manufactures innovative equipment and systems for industrial process/production applications, industrial and municipal wastewater treatment plants and flue gas treatment. Their experience ranges from simple one-machine installations to complex multi-step processes and systems. Reliability, ease of operation, rugged design, proven performance, and superior customer service are hallmarks of Komline-Sanderson installations.

Technology Description:

The Komline-Sanderson Biosolids Drying System uses indirect drying technology to convert municipal and industrial biological sludge into a sterile, free flowing granular product. The dried solids can be beneficially reused as a slow release nitrogen fertilizer, soil amendment additive or as a green fuel in a boiler and cement kiln. The K-S Biosolids Drying System produces an EPA classified Class A Biosolids.  

The K-S Paddle Sludge Dryer is used worldwide for drying a variety of sludges, biosolids and by-products, to generate dry stable products, reduce disposal cost and convert waste into marketable by-products. Dual counter rotating shafts with unique intermeshing wedge shaped paddles produce uniform heating and high heat transfer rates. The use of hollow paddles for heat transfer results in a compact machine. Indirectly heated with steam or circulated thermal fluid (hot oil) the K-S Paddle Sludge Dryer has a thermal efficiency of approximately 98%. Non-condensable gas from the dryer that might require treatment for odors is minimal.

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
