What are the 7 stages of water filtration?

While specific systems vary, a comprehensive municipal or whole-house water filtration process often involves seven key stages: 1) Screening, where large debris like leaves and sticks are removed. 2) Coagulation and Flocculation, where chemicals are added to make tiny particles stick together into larger clumps called floc. 3) Sedimentation, where the heavy floc settles to the bottom of tanks. 4) Filtration, where water passes through layers of sand, gravel, and charcoal to remove smaller particles, parasites, and bacteria. 5) Disinfection, where chlorine or UV light is used to kill any remaining viruses and bacteria. 6) pH Adjustment, where chemicals are added to balance acidity and prevent pipe corrosion. 7) Storage and Distribution, where treated water is stored in clean reservoirs before being pumped to homes. Some advanced home systems might include additional steps like reverse osmosis or activated carbon polishing, but these seven stages represent the standard framework for ensuring safe, clean drinking water on a large scale.
