The device as recited in claim 1, wherein said filter rack is attached to the top of said container. 3. The device as recited in claim 1, wherein said filter rack has a dewatering connection and said device further comprises a pipe, said pipe connecting said dewatering pump to said filter rack via said dewatering connection, said pipe passing through said opening of said container. 4. The device as recited in claim 1, wherein said filter rack has a dewatering connection and said device further comprises a pipe, said pipe connecting said dewatering pump to said filter rack via said dewatering connection, said pipe passing through the wall of said container. 5. The device as recited in claim 1, wherein said moving means is a winch having cables that are attached to said filter rack. 6. The device as recited in claim 5, wherein said filter rack includes lifting lugs to which said cables of said winch are attached. 7. The device as recited in claim 1, wherein said filter rack further includes: a pipe header defining a plane; and pipe branches extending from said pipe header. 8. The device as recited in claim 7, wherein said cylindrical filter elements are connected to said pipe header and said pipe branches, and wherein said cylindrical filter elements, said pipe header, and said pipe branches are in fluid communication with said dewatering pump. 9. The device as recited in claim 8, wherein said filter elements have axes, and wherein said cylindrical filter elements are vertically oriented so that said axes of said cylindrical filter elements are perpendicular to said plane defined by said pipe header. 10. A device for dewatering wastes, comprising: a container having an opening; a filter rack carried within said container said filter rack having cylindrical filter elements carried thereon; means contained within and attached to said container for moving said filter rack; and a dewatering pump external to said container and that is in fluid communication to said filter rack. 11. The device as recited in claim 10, wherein said filter rack has a dewatering connection and said device further comprises a pipe, said pipe connecting said dewatering pump to said filter rack via said dewatering connection, said pipe passing through said opening of said container. 12. The device as recited in claim 10, wherein said filter rack has a dewatering connection and said device further comprises a pipe, said pipe connecting said dewatering pump to said filter rack via said dewatering connection, said pipe passing through the wall of said container. 13. The device as recited in claim 10, wherein said moving means is a winch having cables that are attached to said filter rack. 14. The device as recited in claim 13, wherein said filter rack includes lifting lugs to which said cables of said winch are attached. 15. The device as recited in claim 10, wherein said filter rack includes: a pipe header defining a plane; and pipe branches spaced evenly along said pipe header and that extend from said pipe header, wherein said cylindrical filter elements are connected to said pipe header and said pipe branches. 16. The device as recited in claim 15, wherein said pipe header, said pipe branches, and said cylindrical filter elements are in fluid communication with said dewatering pump. 17. The device as recited in claim 16, wherein said cylindrical filter elements have axes, and wherein said filter elements are vertically oriented so that said axes of said filter elements are perpendicular to said plane defined by said pipe header. 18. The device as recited in claim 15, wherein said pipe header of said filter rack has attached wheels that guide said pipe header as it is being moved in said container, and wherein said pipe header, said
