In animal agriculture in the United States and elsewhere antibiotics are provided to swine for therapeutic reasons as well as for growth promotion. Many antibiotics that are fed to or injected into swine may pass through the swine unmetabolized and therefore end up in the swine manure that is passed into the treatment system. Accordingly it is of considerable interest that an economical and effective means of treating these antibiotics prevent or minimize their introduction into the environment during their field application Figure . 331 2008 by Taylor Francis Group LLC 332 Fate of Pharmaceuticals in the Environment and in Water Treatment Systems FIGURE Sludge pump used to transfer lagoon slurry from lagoon to adjacent fields.
