Fetzer Vineyards to install BioFiltro BIDA System at Mendocino winery in US


Fetzer Vineyards has plans to install BioFiltro BIDA System at its Mendocino winery, thereby becoming the first American winery to use the closed-loop biological wastewater treatment system to process 100% of its winery wastewater.

The BIDA System, powered by billions of earthworms working rapidly together with beneficial microbes, will begin processing Fetzer Vineyards' wastewater during the 2016 harvest season.

This will enable energy savings up to 85% over current wastewater treatment technologies and optimize water conservation measures in support of the fight against climate change.

Fetzer Vineyards CEO Giancarlo Bianchetti said: "It's essential that we constantly ask ourselves if there is a better, more efficient and more regenerative way to approach our business, including the way we work with water.

"BioFiltro offers a compelling process that aligns with our business goals as well as our overarching objective to leave the world a better place than we found it."

BioFiltro's BIDA System is a passive aerobic bioreactor that catalyses the digestive power of microbes and selected species of red earthworms to naturally remove up to 99% of contaminants from Fetzer Vineyards' wastewater, in just four hours.

The chemical-free system consumes less electricity than traditional wastewater treatment technologies such as aeration ponds, which require constant electricity to pump and circulate water.

Further, the BIDA System works efficiently year-round in spite of seasonal fluctuations in wastewater flow like those seen in the wine industry, and generates compost-enhancing castings from worm digestion, thereby returning nutrients to the soil.
