Worms And Wood Shavings Filter Wastewater At Fresno State's Dairy

Worms and wood shavings are filtering dairy wastewater at the Fresno State dairy.{} It's an experimental project being conducted by Biofiltro USA. The company is trying to show that treatment can turn wastewater into a reusable resource.

Sanjar Taromi is the chief marketing officer for Biofiltro USA{}and one of the leaders of the experimental project at Fresno State.{} "The water is moving through that thick worm casting layer and it's full of micro-floral beneficial micro-organisms that are further cleaning and scrubbing out the organic and nutrient contaminants."

So the worm manure is the key ingredient that filters the water. In the end the water looks like tea or an amber beer.{} Taromi says it takes{}roughly four hours after the sprinkling on top to become a finished product.

As the worms do their thing they are also creating by-products.{} Taromi says the worm population doubles in sixty days plus the worm casting is the most expensive and beneficial soil amendment in California right now.{} Both can be sold for profit.

Right now the experimental project can filter 3000 gallons of water a day.{} But Taromi says when it comes to size the sky's the{}limit.{} All it takes is more worms and wood shavings.{}{}
