Versatile organisms that can switch between aerobic and anaerobic survival depending on the environment. The "Food-to-Microorganism" (F/M) Balance
Require oxygen, which is often added mechanically in aeration tanks. They are highly efficient at breaking down organic pollutants into CO2cap C cap O sub 2 and water. Wastewater Bacteria (Wastewater Microbiology)
Rapid growth where bacteria multiply but may not form heavy flocs, leading to poor settling. Versatile organisms that can switch between aerobic and
Specialized bacteria remove nitrogen (nitrification/denitrification) and phosphorus to prevent eutrophication in the environment. Key Types of Bacteria Bacteria are primarily classified by how they use oxygen: Rapid growth where bacteria multiply but may not
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.
Bacteria consume biodegradable organic compounds (food waste, oils, proteins), converting them into energy, new biomass, and gases like CO2cap C cap O sub 2
Thrive in oxygen-free environments, such as sludge digesters. They break down complex waste into biogas (methane), which can be harvested as an energy source.
