A two year study completed by UC Davis's Department of Animal Science regarding the denitrification-nitrification process of our Fanelli Dairy plant has been published in Frontiers of Microbiology. In it, research shows that the nitrogen removal capacity of our systems and vermifiltration is due to the microbial conversion of ammonia. Earthworms contribute indirectly to this process by facilitating microbial growth, aerobic conditions in the system, and anaerobic micro-environments in their guts.
"Our research showed that BioFiltro's vermiculture dairy manure technology reduces atmospheric nitrogen losses by 90%. After studying the microbiology, we now know that denitifiers take various nitrogen compounds and convert them to atmospheric nitrogen (N2). Great technology."

Common practice in wastewater management for dairies and livestock is to separate solids and use the liquid waste to irrigate crops. Excess nitrogen, however, results in groundwater contamination and/or poor crop yield which has caused authorities to implement nutrient management plans to to curb environmental damage. BioFiltro’s BIDA® system effectively reduces the amount of Total Nitrogen and Ammonia present in dairy effluent by ≥70% and Phosphorus by ≥30%, enabling clients to make efficient and controlled nutrient application.
