- Starting the process with coagulation. The coagulation step mixes certain coagulants, like aluminum sulfate, with the water to change the charge of the particles of undesirable elements in the water. This change in charge causes them to clump together into larger groups called flocs.
- Flocculation makes things bigger yet. The next step of treatment agitates the flocs so they run into one another and stick, making even bigger
