![]() “Because aeration of our system is achieved through the burrowing movement of worms, our annual energy bill can be up to 95% less than competing technology,” she says. From there it will be dispersed across the worm bed via an irrigation system and will percolate down and out through exit pipes. Water from the barn will flow through a solid separator, then into an equalization tank. Worms and microbes are then introduced into the system, and they create a biofilm, which digests most of the contaminants. It starts with a containment vessel filled with wood chips, river rock, and drainage cells. The patented Biodynamic Aerobic System (BIDA) transforms liquid waste into water that is usable for irrigation. “By having access to cleaner water, farmers can minimize their environmental impact and secure the future for their operations.”īioFiltro has developed a worm-powered wastewater system to remove 70% to 90% of nutrients from liquid manure. “When it’s done for a long period of time or incorrectly, land application can contaminate the soil or groundwater to a point where it’s no longer viable for use,” says Mai Ann Healy, head of business development, BioFiltro. The most common wastewater treatment method is land application. We try to advance ideas that show the greatest promise in market opportunity that also promote sustainability, create new revenue streams, and create circular economies on the farm,” Day says. “This is an innovation-style challenge that invited any ag tech start-up in the manure management space to present ideas. The yearlong cohort wrapped up with a virtual pitch competition in June 2020 with each of the start-ups vying for a grand prize of $50,000 in nondiluted capital. Markets Analysis Back to Markets AnalysisĬhosen from 63 applicants, the Challenge guided eight companies through a commercialization curriculum, which included mentorship and an introduction to investors.Clean water can be discharged or reused as animal drinking water, the UF and FO concentrates are organic fertilizers. Isolation of RO membranes from the wastewater, we reduce downtime for cleaning, and extend the life of the spiral RO elements, and produce very clean water effluent. ![]() The advantage of this system is that the FO can handle high solids wastewater rich in organic matter, has a very low tendency to foul, and uses very little energy because the wastewater is pumped through it at low pressures. The brine is recycled back to the FO system for reuse. The salt solution is pumped into a (RO) system where clean water is produced along with brine. ![]() ![]() The UF permeate is processed in a forward osmosis (Fo) system water is extracted through the membrane and into a salt solution. 90% of the phosphorous and organic nitrogen are rejected by the UF. The UF system is comprised of multiple tubular UF membranes which reject suspended solids, FOG, and pathogens. We have designed, fabricated, and commissioned a manure filtration system comprised of a stainless steel ultrafiltration system and a combination of forward and reverse osmosis to turn liquid manure into organic fertilizers and clean water.
