Question

Quizplus · Accepted Answer

The treatment process described—horizontal flow in an agitated aeration tank—is characteristic of the activated sludge treatment method. This method involves the continuous aeration of wastewater mixed with microorganisms (sludge) to promote biological degradation and settling of solids. Lagooning refers to the treatment of wastewater in large, shallow ponds, while trickling filter processing involves passing wastewater through a bed of fixed media to which microorganisms attach and treat the water. Endogenous respiration is a natural process where microorganisms break down organic matter in the absence of external electron acceptors.
