This positive charged is connected with negatively charged in order to neutralize all dissolved particles and dirt. After this chemicals bind to particles and form larger particle, called floc. The next step in the process is sedimentation where the floc settles down to the bottom of the water. The third step is filtration which is one of the most important because dissolved particles such as various chemicals, viruses, bacteria, and dust are removed when the water passes through filters.
