BioFiltro’s BIDA System is a closed-loop biological wastewater treatment system. The worm-and-bacteria powered process can remove up to 99 percent of Biological Oxygen Demand (BOD) and Total Suspended Solids (TSS) and 70-90 percent removal of nitrogen, oil and grease in four hours, according to BioFiltro’s regional manager Mai Ann Healy.
Healy told EcoWatch that “most other treatment systems require days, if not weeks, to achieve these results.”
BioFiltro currently has 129 facilities installed in six countries. They process the wastewater from the Chilean Air Force Base on Antarctica as well as the Atacama Desert, which is the driest desert in the world. The company is currently constructing plants in California to serve the needs of food processors, wineries, waste haulers and sanitary waste, Healy said.
