What is activated sludge?
Activated sludge: The activated sludge process uses an aeration tank with aerators or diffusers. As the organic material in the waste breaks down, it forms large bacteria-containing chunks known as flocs. The flocs then settle to the bottom of the tank, where they are easy to remove.
What happens to anaerobic wastewater?
During anaerobic wastewater treatment processes, microorganisms break down waste matter in the absence of oxygen. These processes often occur in an airtight, enclosed bioreactor filled with sludge. The sludge contains anaerobic bacteria and other beneficial microbes. In the bioreactor, the microorganisms digest the organic matter in the wastewater.
How does wastewater settle in lagoons?
In the lagoons, wastewater settles into different layers, with liquid layered over the sludge to prevent oxygen from reach ing it during microbial digestion. Sludge blanket reactors: Anaerobic sludge blanket reactors send wastewater through a floating blanket-like layer of sludge.
What is an anoxic environment?
Anoxic conditions involve environments in which molecular or free oxygen (O 2) is absent, though bound oxygen may be present. “Anoxic” refers to the state of the environment rather than microorganisms and their processes. In wastewater treatment, anoxic conditions differ from anaerobic conditions based on the presence or absence of nitrogen. ...
Why do wastewater treatment plants use anaerobic treatment?
For this reason, treatment plants often use anaerobic treatment first to remove a significant part of the wastewater’s organic matter before sending it on for further aerobic treatment . The two methods are also useful independently.
What is the solution to wastewater?
An alternative treatment solution is CO2. When injected directly into wastewater, CO2 causes the formation of carbonic acid, which naturally adjusts the pH to a suitable level. This treatment method is easy to control, and the byproducts it creates are harmless. None of the CO2 is released into the environment.
