Sedron Technologies’ patent pending Varcor Processor provides a highly efficient solution for processing liquid waste streams that concentrates and recovers the outputs into pathogen-free solid and liquid fractions. This approach to treatment is extensible to many liquid waste streams, such as livestock manure, septic wastewater, and industrial liquid waste.
Our Varcor Processor is a complete treatment solution in that, beyond just separating the solid and water, also heats, sterilizes, and distills the constituent components. At the system output, the distilled reuse water is treated to desired quality standards including those sufficient for environmental release, irrigation, reclaimed water, or wastewater treatment discharge. The solids produced are pathogen-free and are capable of being sold as a commodity in many cases. The Varcor Processor includes nutrient recovery technology that enables the capture of a concentrated ammonia solution for certain waste streams that can be sold as a fertilizer.
The Varcor technology is fundamentally based upon a well-proven process known as vapor recompression distillation. The solid and liquid fractions are separated through thermal evaporation and the resulting vapor is sent to a compressor, where it undergoes mechanical recompression. The compressed vapor is then used as the heat source for the evaporation process; in transferring its heat, the vapor condenses and forms a water output. The remaining vapor is concentrated and condensed into an ammonia solution. Due to the thermal process involved, all three outputs: the water, the solids, and the concentrated constituents, are guaranteed to be pathogen-free. This technology solves existing market problems and customer pain points by offering reduced operating costs, producing by-products that have inherent value, and offering more convenient use.
VARCOR PROCESSOR SCHEMATIC & OUTPUTS
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 Technologies’ Varcor Processor, manure will be efficiently distilled into 1) water clean enough to feed back to the cows, 2) dry, sterile and stable solids for bedding and/or soil amendments, and 3) 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.

Manure is collected, combined with wash and process water and pumped to storage lagoons until safely applied to fields as a fertilizer when the crops need the nutrients. Usually, little to no treatment happens prior to lagoon storage, and its contents remain contaminated by high levels of fecal coliform bacteria. Rain further dilutes the manure, adding as much as 2 to 5 times the volume of water to these lagoons. If improperly managed, manure stored in these lagoons can contaminate both surface and ground water with nutrients and pathogens.
Used on a small number of dairies, anaerobic digesters are effective at producing biogas, but do not completely eliminate fecal coliform bacteria nor provide nutrient recovery. They also require significant capital investment. Farmers generate limited income by combining other organic waste materials with the manure, which can significantly increase the amount of nitrogen and phosphorus produced when compared to manure alone. These added nutrients often force farmers to acquire more land and lower application rates in order to balance these additional nutrients with crop production—adding considerable time, effort and expense to the farmers’ bottom line.
