The health of a treatment plant depends on the , which is the amount of incoming waste (food) relative to the amount of bacteria available to process it.
Bacteria secrete a "slime layer" that allows them to clump together into flocs . These flocs are heavy enough to settle to the bottom of tanks, effectively separating solids from the purified water. Wastewater Bacteria (Wastewater Microbiology)
In a wastewater treatment plant, microorganisms function as a "biological engine," transforming hazardous waste into clean water. Bacteria are the most critical of these organisms, making up roughly in a typical treatment system. Core Microbial Roles The health of a treatment plant depends on
