One common drinking water treatment system involves the use of a carbon filter. With this drinking water treatment system, coagulation removes dirt and other particles suspended in water. Initially, alum and other chemicals are added to the water to form tiny sticky particles called floc, which attract dirt particles. The combined weight of the dirt and the alum basically the floc become heavy enough to sink to the bottom during sedimentation. While the heavy particles, or floc, settle to the bottom, the clear water moves to the filtration process where it is passed through filters with layers of sand, gravel and charcoal that help remove even smaller particles.
