Metzger – Evaporation

Pure. Sustainable. Effective.

About the Company:

Since more than two decades, we at MKR have been making it possible to handle process media intelligently. We offer modular solutions which optimize production cycles involving liquids in an ecological and economic way. MKR-Systems recycle all types of process media by cleaning and treating them. This is good for your income statements as well as for the environmental assessment of production and waste management companies.

About the Solution:

Biogas plant operators and the population have the greatest benefit from what we offer. ? The value added of a biogas plant is derived from the electricity and heat production. But rather, the fertilizer generated from the substrate is regarded as disruptive. A 500 kW plant produces up to 12,000 tons of Digestate per year. Twelve thousand tons of Digestate is: 700 trips across the fields. This could be but much less! Residents and politicians hold little of this burden. Only water is removed, 70% of the water is removed! So - out with the water and the digestate is thickened!

Solution 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
  Metzger has been unresponsive to Newtrient's multiple attempts to supplement or validate the information about this technology.
