Methods for treating animal waste, particularly liquid fractions separated from manure, with high purity oxygen are provided to increase the dissolved oxygen content of the wastewater and minimize stripping of volatile gases. In particular, methods of the invention for treating animal waste comprise separating animal waste into a liquid fraction and a solid fraction, and aerating at least a portion of the liquid fraction with oxygen having a purity greater than 90% until the dissolved oxygen (DO) level of the liquid fraction is between about 2.0 mg/L and about 9.0 mg/L. |
