The purpose of tertiary treatment is to provide a final treatment stage to further improve the effluent quality before it is discharged to the receiving environment (sea, river, lake, wet lands, ground, etc.).
More than one tertiary treatment process may be used at any treatment plant.
If disinfection is practised, it is always the final process.
It is also called "effluent polishing".
