Conventional Method

Chlorination

Primary disinfection of water

Coagulation

Quick mixing of water with chemicals (alum)

Flocculation

Encourages forming of solids (flocc)

Sedimentation

Water slows down→ flocc settles out

Dual media filtration

Filtered by gravity through filter

GAC Filter

Water filtered by carbon pores in filter

fluoridation

Safe amounts of chlorine & fluoride added

Ozone, BACC, & Membrane Filtration

Ozone

Breaks down organic particles

BACC

Filtration through carbon bed

Membrane filtration

Ultra-filtration removes microorganisms

Storage

Reservoirs (e.g. Hanlan Reservoir)

Distribution

  • Storage reservoir → high lift pumps
  • Freedermains (transport water from reservoir)
