Abstract:
1. A method of controlling a ballast water treatment system having a back-pressure formation unit, the method comprising the steps of: (A) filtering ballast water using a filtering unit, comprised of: (B) sterilizing the filtered ballast water using an ultraviolet treatment unit that receives the flow of filtered ballast water from the filtering unit and that includes a temperature sensor and an ultraviolet lamp for sterilizing the filtered ballast water using ultraviolet rays to provide a flow of sterilized ballast water; (C) checking and forming an amount of back-pressure in the filtering unit meeting a reference value to enable a back washing operation to be smoothly performed while maintaining the efficiency of the ultraviolet treatment unit by maintaining the flow of filtered ballast water to the ultraviolet treatment unit, using a back-pressure formation unit comprised of:
