Manure and Digestate Management
- Turn manure into clean water and concentrated fertilizer
- Manage pathogens by removing >99.9% of pathogens just with ultrafiltration
- Add our Nutrient Concentration & Water Reclamation System to generate water suitable for direct discharge or reuse as drinking water in the barn

How does the BioEliminator™ work?
- We recommend using a screw-press to remove coarse solids from raw manure prior to digestion.
- The liquid manure (pressate) is then passed through our proprietary high-pressure micronization process to disintegrate solids and create a homogenous mixture ready for digestion.
- We add BioSupport™ to the micronized pressate to ensure microbes have the proper nutrition they need for optional treatment.
- The mixture of pressate and BioSupport™ then flows through our patent-pending horizontal anaerobic digester In most cases, these reactors are buried underground alongside barns or existing lagoons in lengths of 40 to 120 feet long. The reactors are filled with a filter material that microbes grow attached to. These microbes consume the organic matter and produce methane-rich biogas (natural gas) that we capture to generate power, heat, or compressed natural gas (CNG).
- By housing the microbes on the filter material inside the reactor, the BioEliminator™ system can remove very high levels of the total suspended solids, organic matter, and E. coli/coliform bacteria present in the waste in less than 5 days. The BioEliminator™ also improves the bioavailability of nitrogen (through mineralization) while capturing some phosphorus as a settled solid that can be easily removed.
- The effluent greywater is ideal for irrigation and the phosphorus-rich solids, removed periodically throughout the year, can be economically transported and applied where needed most.
How does the NCWR™ work?
- Raw manure or digestate is first screened to remove large solids that could clog the filtration system.
- The screened material then goes through an ultrafiltration system to remove all the suspended solids.
- The solids-free water then goes through a reverse osmosis system to produce clean, re-usable water.
Overall, the NCWR system can turn 1,000 gallons of manure or digestate into 700 gallons of clean water and 300 gallons of concentrated liquid fertilizer, all for less that you currently spend hauling and spreading.
How does the BioEliminator™ compare to traditional farm digesters?
Anaerobic digestion is becoming increasingly popular on large farms in the US. However, these digesters tend to suffer frequent upsets, produce a nutrient laden wastewater (i.e. digestate) that can be difficult to manage, and are often poor investments financially. There are several explanations for this lackluster performance:
