The typical steps in a conventional wastewater treatment follows the sequence is
Screening – Sedimentation – Aerobic oxidation – Disinfection – Discharge
The four processes of wastewater treatment are:
  1. Preliminary Treatment
    Screening (screeners, grit chambers, and skimming tanks)
  2. Primary Treatment
    Sedimentation (basically involves the process of sedimentation or settling),
    Chemical-aided Sedimentation
  3. Secondary or Biological Treatment
    Activated sludge process
    Aerated lagoons         
    Sequencing batch reactor
    Aerobic digestion
    Trickling filters
    Rotating biological contractors
  4. Tertiary or Advanced Treatment
    Solids removal
    Biological nitrogen removal
    Biological phosphorus removal
    Disinfection.
