<p>A fluid treatment device (1) includes at least one fluid purification assembly (7) for purifying fluid flowing through the fluid purification assembly (7) to an outlet (10) of the fluid treatment device (1), the fluid purification assembly (7) switchable from and to an operative state in which it is powered to provide a purifying effect; and at least one flow adjustment device (4, 6) for adjusting a rate of flow of fluid through the fluid purification assembly (7). A method of operating the fluid treatment device includes, after a switch of the fluid purification assembly (7) to the operative state, setting the flow adjustment device(s) (4, 6) to establish at a first point in time (t3,t9) a rate of flow at a first value, the first value corresponding to a maximum over an interval from the switch of the fluid purification assembly (7) to the operative state to a point in time (t4) at which the flow of fluid to the outlet (10) is cut off. After the switch of the fluid purification assembly (7) to the operative state, at least if subsequent to the fluid purification assembly (7)'s having been in a state other than the operative state for at least a certain period (Deltat1), settings of at least one of the flow adjustment devices (4, 6)are caused to adjust over a range of values to provide a rate of flow increasing from zero to the first value over a time interval preceding the first point in time.</p> |
