摘要： The present invention relates to a method for determining quality of a fluid, preferably being water. The method involves exposing the fluid to UV radiation to determine a parameter, such as absorbance of the fluid, related to the quality of the fluid and/or for disinfecting the fluid. The method may also involve determining a fouling factor. The invention also relates to a reactor adapted to expose a fluid to UV radiation, the reactor comprising an UV arrangement comprising at least two UV sources and at least one UV sensor. The two UV sources and the one UV sensor being positioned relatively to each other so that the distances (d1, d2) from UV sensor and to each of the UV sources are different from each other so as to provide two different optical path lengths.

摘要： A method of cleaning a liquid fluid filter (2) by means of a at least one cleaning process (BW), wherein said cleaning process (BW) is started after a predetermined time period of operation of the filter or a prede- termined amount of liquid filtered, characterized by detecting a first transfilter pressure value (TMP) between both sides of the filter (2) at a first point in time and detecting a second transfilter pressure value (TMP) between both sides of the filter (2) at a second point in time, calculating a difference value (ΔTMP1, ΔTMP2) of the two detected transfilter pressure values (TMP), comparing said difference value (ΔTMP1, ΔTMP2) with a limit value XX, decreasing said predetermined time period or said predetermined amount of liquid to be filtered between two starts of said cleaning process BW if said limit value XX is exceeded by said difference value (ΔTMP1, ΔTMP2).
摘要翻译：一种通过至少一个清洁过程（BW）清洁液体流体过滤器（2）的方法，其中所述清洁过程（BW）在过滤器的预定时间段或预定量的液体过滤，其特征在于在第一时间点检测过滤器（2）的两侧之间的第一传送器压力值（TMP），并且在过滤器（2）的两侧之间检测第二传送器压力值（TMP）计算两个检测到的传感器压力值（TMP）的差值（＆Dgr; TMP1，＆Dgr; TMP2），将所述差值（＆Dgr; TMP1，＆Dgr; TMP2）与极限值XX进行比较，如果所述限制值XX超过所述差值（＆Dgr; TMP1，＆Dgr; TMP2），则在所述清洁处理BW的两个开始之间预定时间段或所述预定量的待过滤的液体。
