Title: Ship ballast water sterilization method and system
Inventor: BRODIE PAUL F
IPC: B63B17/00
Filed: 2001-03-16
Abstract: A method and system for continuously treating ship ballast water enroute to reduce or eliminate harmful microorganisms therefrom, before discharge of the ballast water into coastal waters. During the ships voyage, and before the ballast water is discharged, the ballast water is continually passed through an interconnected UV sterilization system for treatment by ultraviolet radiation. One or more dispensing pumps are provided to transport the ballast water through the length of the UV system, which includes one or more UV units to process and sterilize the ballast water. In cases where large volumes of water need to be processed or where individual ship design is limiting, secondary piping to divert the flow of ballast water from the main piping system through placement of diverter valves, may be added to incorporate additional UV units or pumps. Flow jets secured to the inside of a ballast tank or hold may also be used to ensure proper circulation and mixing of the ballast water to be treated.

Abstract: A lighting device is provided. The lighting device has LED lamps and so forth with high directivity as light source. The lighting device of the present invention is capable of lighting more uniformly. Few labor for maintenance and inspection is necessary. Rich durability is provided therewith and it can be manufactured in low cost. The lighting device is constituted in such a way that a light source body such as LED lamp and so forth is disposed at an end portion of a cylindrical light transmitting member whose degree of transparency is transparent or translucent.      The constitution causes the light to travel in the axial direction of the light transmitting member. Transparent or translucent island formation body is provided on the inside of internal surface of the light transmitting member. Islands of the island formation body are made to protrude perpendicular to the axial line of the cylindrical light transmitting member. The light emitted from the light source body is irregularly reflected while striking to these islands.
