1. coagulation (change liquid into a thickened mass): removal of dirt and other
particles suspended in water. aluminum sulfate and other chemicals added to water
form tiny, sticky particles called "floc" which attract dirt particles. 2. sedimentation:
heavy particles settle to bottom of sedimentation tank and the clear water moves to
filtration. 3. filtration: water passes through filters made of sand, gravel, and charcoal
that help remove smaller particles. 4. disinfection: small amount of chlorine added to
kill any bacteria or microorganisms in the water. 5. storage: water is placed in a closed
