In recent years, water treatment plants have been designed to provide for prechlorination and postchlorination in conjunction with a variety of intermediate points of application; that is, ahead of filters and sometimes ahead of sedimentation units (postflocculation). This type of design is based largely upon a consensus that postchlorination is a must for disinfection, that prechlorination will aid taste and odor control and prevention of algae growths in sedimentation basins, and that the intermediate points will remedy any unforeseen problems that may arise. This article discusses whether all these points of chlorination are necessary considering the time and expense of additional hardware necessary to meter and transport the chlorine solution.
