Wastewater is taken into account clean up immediately after secondary treatment, but tertiary treatment returns it to a good increased high-quality for launch in safeguarded waters.
Both of those of these treatments are usually presented in prefabricated metal tanks called package deal plants. Oxygen aeration systems combine pure oxygen with activated sludge.
