Safe water supply is fundamental to public health, preventing the transmission of waterborne pathogens.
Purification & Disinfection Steps
- 1. Storage/Sedimentation: Suspended solids settle down, reducing bacterial load.
- 2. Filtration: Sand filters remove fine particulates and microorganisms.
- 3. Disinfection: Chlorination kills pathogens. Orthotolidine test measures free residual chlorine.
