Changing Sanitation & Water Treatment

About the Company:

Sedron Technologies is made up of engineers that fundamentally want to improve the world. They are passionate problem-solvers and original thinkers.  The technologies they develop require multidisciplinary collaboration: from mechanical engineers to electrical engineers; from chemical engineers to software engineers.


Motivated by a strong desire to equip the world with better tools for sanitation and waste management, the Sedron team has revolutionized how waste streams can be processed to eliminate disposal costs and destroy pathogens, while capturing valuable energy and recycling water.  They design and manufacture the most advanced nutrient recovery machines in the world and continue to expand the possibilities for practical waste treatment systems.


Sedron’s goal is to make it economically attractive for businesses to maintain environmental responsibility.  Their solutions are built not only to support the expense of their own operation, but also to pay back their capital expense over time and accrue significant cost savingsfor those using the product.

About the Solution:

Sedron Technologies' Advanced Vapor Recompression Distillation (Varcor) system separates liquid waste streams  (<1% to 20% solids) into distinct byproducts using proprietary and industry-proven technologies. This approach to treatment is extensible to many liquid waste streams, such as livestock manure, septic wastewater or biosolids, industrial liquid waste, and stillage.

Advanced Varcor technology is transformational to manure management on dairy farms. Using our methods, farmers can achieve compliance with environmental regulation while accruing significant cost savings as well as additional revenue streams. With Sedron Varcor technology, manure will be efficiently distilled into water clean enough to feed back to the cows, dry, sterile and stable solids for bedding and/or soil amendments, and concentrated liquid, organic nitrogen fertilizer.

Through implementation of this technology, the farm will recognize significant energy efficiencies from reductions in on-farm electrical and fuel use required during manure management activities such as wastewater storage, agitation, pumping and hauling, as well as  associated labor and maintenance costs. Significant additional environmental and energy-related benefits include becoming a zero-discharge dairy, GHG reductions due to reduced storage lagoon wastewater volume, as well as displacement of inorganic fossil fuel-based fertilizers.

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:

Janicki Bioenergy has in the past worked with Gates Foundation on a highly visible wastewater treatment system for Africa, delivering multiple units to Africa in a successful application they entitled the Omni Processor. Janicki Bioenergy, renamed Sedron Technologies, is now developing a new technology to treat dairy wastewater here in the US. If successful, this new and innovative dairy approach would use available electricity from the grid to operate the thermal evaporation system to produce dried manure solids, dischargeable clean water and aqueous ammonia. Sedron Agriculture is in the midst of starting their first Varcor system on a partner dairy to demonstrate and refine the system for the United States dairy industry.

Newtrient is actively working with Sedron in their attempts to bring it's Varcor technology to commercialization and is excited about both the potential of the technology and the capabilities and track record of the company.

As the technology is still in development, Newtrient has not yet evaluated the Sedron Agriculture system using Newtrient's 9-point scoring process, but Newtrient will continue to work with Sedron Agriculture and update the catalog as information and data become available.
