
Step 1 - Preliminary
 Screening


Step 4 – Disinfection (sometimes last)
 Chlorine/Ultraviolet light
 Kills microorganisms

Step 5 – Advanced Treatment
 Removal of phosphorous & nitrogen
 Then returned to rivers/lakes
Wastewater Treatment Plant
Septic System
Rural setting
 Personal treatment “plant”

 Sewage pumped to tank
 Bacteria breaks down
○ Sludge
○ Scum
○ Effluent
 Sludge settles
 Scum floats
 Effluent runs to distribution box
 Box sends effluent to field
