This slide presentation presents information on 10 lessons: adverse impacts of enhanced coagulation are not usually that bad; costs at the treatment plant are usually not unbearable; utilities usually anticipate problems and take preventative measures; concrete standards, materials and installation practice are important; the role of water quality in concrete degradation is poorly understood; free chlorine is highly corrosive; metallic infrastructure (pumps and pipes) bear close monitoring; coagulation can change corrosion in the distribution system; inhibitors used in the treatment plant must be compatible with coagulation goals; and, expect the unexpected.
