How Water Treatment Works: A Step-by-Step Process Flowchart #223035 (License: Personal Use)

The diagram shows water entering from homes, offices, and industry, passing through a bar screen and grit tank (Stage 1), then moving to sedimentation (Stage 2) and clarification (Stage 3). It continues through aeration, settling, digestion, and finally disinfection using chlorine or UV before being returned to the environment or reused. Arrows indicate flow direction and recycling loops for sludge and treated water.
