PURPOSE: A ballast water processing method and a ballast water processing unit for cleaning cohesive floc separated from ballast water are provided to naturally remove the air from the magnetic floc and disappear microorganism and the bacteria contained in the magnetism. CONSTITUTION: A ballast water processing method comprises next steps. The magnetism floc which contains microorganism and bacteria adds the magnetic pigment in the ballast water(S100). The magnetism floc is collected from the ballast water. The thermal death point of the bacteria and the microorganism which predetermines the magnetism floc collected. The magnetism floc is penetrated in the conduit line. The conduit line inserting and penetrates the magnetism floc is heated. The pressure within the conduit line is measured. The state of the conduit line is examined.
