Both of such treatments are often delivered in prefabricated metal tanks identified as offer crops. Oxygen aeration units mix pure oxygen with activated sludge. A richer focus of oxygen lets the aeration time and energy to be shortened from six to two hrs, minimizing the necessary tank volume.
In the event the time period "wastewater treatment" is confusing to you, you might think of it as "sewage treatment."
