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. |
