Abstract: Disclosed herein is an ultraviolet sterilizer having a vibration-proof function. The ultraviolet sterilizer includes an ultraviolet sterilization unit. The ultraviolet sterilization unit has an inlet through which ballast water is drawn thereinto, an outlet through which the ballast water is discharged therefrom, and an ultraviolet lamp located between the inlet and the outlet. The ultraviolet lamp applies ultraviolet rays to the ballast water. The ultraviolet sterilizer further includes a cap which supports each of the opposite ends of the ultraviolet sterilization unit, and a shock absorption unit which is elastically compressed at a first end thereof by the cap while a second end thereof compresses an end of the ultraviolet lamp. Thereby, even if the ultraviolet sterilization unit vibrates, the sleeve pipe or the ultraviolet lamp can be prevented from being damaged, and explosive gas which may cause the ultraviolet sterilizer to explode is also prevented from entering the cap.

Abstract: Disclosed herein are a ballast water treatment system having a back-pressure formation unit and a control method thereof. Back pressure in a filtering unit is checked and formed during a back washing operation for a filter of a filtering unit, thus enabling efficient back washing operation. Both a method of physically filtering ballast water using the filter and a method of sterilizing ballast water using ultraviolet rays are used to treat ballast water, thus preventing secondary contamination due to byproducts, and preventing the contamination of a ballast tank. A flow rate of ballast water introduced into an ultraviolet treatment unit is controlled such that the efficiency of the ultraviolet treatment unit is not reduced, while back pressure is formed in the filtering unit, thus increasing the overall treatment efficiency of the ballast water treatment system. Further, the filtering unit or the ultraviolet treatment unit may be automatically washed.

Abstract: Disclosed herein is an apparatus having a double wiper structure for sterilizing ballast water. Each wiper for use in removing foreign substances from an ultraviolet lamp has a double structure including a main wiper part and auxiliary wiper parts. The auxiliary wiper parts are disposed on opposite sides of the main wiper part so that when the wiper body is moved forward or backward, the corresponding auxiliary wiper part primarily removes foreign substances before the main wiper part wipes the ultraviolet lamp unit. Each auxiliary wiper part includes an inclined protrusion and a pointed part so that friction between the surface of the ultraviolet lamp and the auxiliary wiper part can be minimized. The main wiper part includes a first blade and a second blade that are respectively disposed on opposite sides of a depression formed in an inner circumferential surface of the main wiper part.
