Turning Cow Manure into Drinking Water

| 8/4/2009 10:43:17 AM

Cow ButtA Wisconsin farmer has figured out a way to turn cow manure into water that “tastes just like the kind you get at the grocery store.” John Vrieze and his son  have developed an innovative four-part filtration system that effectively converts the manure from his 1,200 cows to potable drinking water and highly enriched fertilizer. Vrieze’s son tells Wisconsin People & Ideas that although the technology is not new (it’s typically used in food processing and water treatment plants), “its use in a dairy farm is unprecedented.” The downside? The equipment requires an awful lot of fuel. With rising fuel costs the economy in shambles, Vrieze has been forced to revert to “conventional manure management” for the moment.
