摘要： The present disclosure relates to a method and control unit for controlling a ballast water treatment system. In the method a prevailing operational condition value (PCV) relating to the filter unit and/or the treatment unit is determined by means of a sensing means. Based on the determined prevailing condition value, a modifying action is performed. The method further comprises, when the steps and/or are repeated during a determined time interval, tracking a trend for the development of the prevailing operational condition values and/or a frequency for the modifying actions. Based on the tracked trend, a moment in time where a critical value for the prevailing operational condition value is reached is predicted-According to the invention the ballast water treatment system is controlled by initiating the performing of the modifying action based on the prediction and/or the value for the determined prevailing condition, which ever value reaches its reference value (RVT; RV, RR) first.
