To provide water that is safe for human consumption, there are a number of processes that the water treatment industry use. Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralises the negative charge of dirt and other dissolved particles in the water. When this occurs, the particles bind with the chemicals and form larger particles, called floc. To separate the floc from the water, it is allowed to settle and fall to the bottom of the water during the sedimentation process. The clear water is then passed through various filtration compositions and sizes to remove any remaining dissolved particles. Finally, the water is disinfected with further chemicals, such as chlorine, to kill any bacteria and protect the water as it is piped to homes and businesses.
