Alternate hydrophilic and hydrophobic fiber filters are used to remove particulate matter and oil from aqueous animal processing wastes, such as those from cannery operations, poultry processing plants and packing plants. The fiber used to make the filters is preferably a low-lignin content, cellulosic fiber that is digestible by ruminating animals. The adsorbed oil in the hydrophobic filter may be removed and the filter reused. The hydrophilic fiber filter containing particulate matter may be dewatered and converted to animal feed or fertilizer.
