Water suppliers use a variety of treatment processes to remove contaminants from drinking water. These individual processes may be arranged in a “treatment train” to remove undesirable contaminants from the water. The most commonly used processes include filtration, flocculation, sedimentation, and disinfection. Some treatment trains also include ion exchange and adsorption. A typical water treatment plant would have only the combination of processes needed to treat the contaminants in the source water used by the facility.
