An Answer to Water Pollution?
A new technology is moving into Northeast Wisconsin which is said to be a “solution” for processing liquid waste. It does so by concentrating and recovering the processed waste fractions into pathogen-free solid and liquid products. It thus, reduces or eliminates the need to spread millions of gallons of raw, liquefied manure on our fragile and shallow soil structures.
One of the companies bringing this technology to Northeast Wisconsin is Sedron Technologies (www.sedron.com). Their processor is called the Varcor™ system. According to Sedron the Varcor™ system is based upon a process known as mechanical vapor recompression. In the process, the solid and liquid portions of the waste are separated through heating and evaporation. The vapor evaporate is then sent to the vapor compressor, causing it to be squeezed into steam, which is then used to heat and evaporate more manure, and again returned back to the recompression mechanism for recompression and for further evaporation of waste.
As the water is removed from the waste through heating, the dried solid portions of the waste are removed as a sterile dry and solidly compacted bedding or soil amendment. Also resulting from this process is a nutrient-rich, saturated liquid that is then diverted into a separate, steam-heated distillation process that will separate off aqueous ammonia (NH4OH) and other low boiling point constituents from the vapor. The final component, steam, is Schematic diagram of Varcor™ System Sedron.com then condensed back to clean water, 6 now sterilized for cows to drink. There is an online photo of Bill Gates drinking that water.
The Sedron industry believes that the Varcor™ system will be a complete game changer to the management of manure on dairy farms and other applications. It is designed to process various liquid streams of waste including organic, swine, dairy, or raw waste from septic system tanks.
This technology could help farmers achieve compliance with environmental regulations as well as accruing significant cost savings and additional revenue.
Allegedly, with this Varcor™ processing system, manure will be distilled into:
clean water for cows
dry, sterile, and stable solids for use as bedding and/or soil amendments
concentrated liquid, organic nitrogen fertilizer
Sedron claims that this system will enable industrial farms to potentially have zero liquid manure for field application. If all claims are true, this would be a dream come true for the ground and surface waters of Northeast Wisconsin. However, there are still many unanswered questions and details needing to be addressed as we learn more about the Varcor™ system, but any attempt to improve our degrading environment is a step in the right direction.
