Hogs have a reputation for not being the cleanest of animals, and as it turns out, neither is their waste.  But USDA scientists in South carolina have adapted a new technology from Japan that may soon enable large hog farms to more cheaply and effectively treat all that suey sewage.  Hog waste contains high levels of ammonia, but with this new technology, bacteria are incased in polymer gel pellets, acclimated to the high levels of ammonia, and then set to work breaking it down into nitrite, and then nitrate, which can be turned into harmless nitrogen gas.  With tests showing the pellets removing 97% of ammonia in wastewater, farmers could soon be going hog wild over this new hog waste technology.
