Tertiary Treatment
- Tertiary Treatment is next wastewater treatment process after secondary treatment. This step removes stubborn contaminants that secondary treatment was not able to clean up; waste water effluent becomes even clear in this treatment process through the use of stronger and more advance treatment systems.
- Treatment levels beyond secondary are called advance or tertiary treatment.
- Tertiary treatment technologies can be extension of conventional secondary biological treatment to further stabilize oxygen-demanding substances in the wastewater.
- Tertiary treatment may also involve physical-chemical separation techniques such as media sand filters, carbon adsorption, and flocculation/precipitation, membranes for advance filtration, dechlorination and reverse osmosis.
