Tertiary Treatment

Advanced wastewater treatment methods focused on removing nutrients like nitrogen and phosphorus.

Chemical Oxygen Demand (COD)

A measure of the amount of oxygen that can be consumed by chemical reactions in a water sample.

Algal Growth

The increase of algae in water bodies that can result from excess nutrients, particularly nitrogen and phosphorus.
