Question

What is treitary treatment?

Answer 1

Tertiary treatment is the final cleaning process that improves wastewater quality before it is reused, recycled or discharged to the environment.

The treatment removes remaining inorganic compounds, and substances, such as the nitrogen and phosphorus.

Bacteria, viruses and parasites, which are harmful to public health, are also removed at this stage.

Wastewater flows from the biological reactor and IDAL to a pumping station and meet in the flash mixer.

Alum is used to help remove additional phosphorus particles and group the remaining solids together for easy removal in the filters.
