Table 1: Characteristics of the water before and after each treatment (volume refers to treated water; time refers to minutes to complete the experiment). These values represent only one measurement each. The characteristics of the water for the three different groups of DBP are presented together when the volume of water was sufficient to take samples for all the studied DBP at once.
