This biological wastewater treatment process uses aeration and a biological floc composed of bacteria and protozoa to treat sewage or industrial wastewaters. The process involves oxidizing organic pollutants, producing a waste sludge, and separating it from the clear treated water. This is a common secondary treatment method where oxygen is pumped into the aeration tank to foster the growth of bacteria that break down organic matter.

Secondary Clarifiers: Separating Clarity from Complexity
Secondary clarifiers play a pivotal role in wastewater treatment systems, particularly after the biochemical oxidation stage. Their mission? To further purify treated wastewater by allowing microorganisms and fine particles to settle.
