Anoxic suspended growth reactors The suspended growth reactor is simply a tank in which nitrified wastewater is mixed with a “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.

For the treatment of wastewater it is useful to distinguish between two oxygen-free treatment systems, the anaerobic tank where organic carbon is removed, and From Wikipedia, the free encyclopedia Anoxic waters are areas of sea water, fresh water, or groundwater that are depleted of dissolved oxygen and are a more severe condition of hypoxia. The US Geological Survey defines anoxic groundwater as those with dissolved oxygen concentration of less than 0.5 milligrams per litre. Anoxic Tank • High Dissolved Oxygen in Mixed Liquor May Inhibit Denitrification • Higher Level of Nitrification in the Aeration Zone and Insufficient Nitrogen Removals in the Preceding Anoxic and Aerobic Stages Can Overwhelm the Second Anoxic Tank and Cause Nitrates to Leak into Anoxic tanks are just tanks with mixers. Thats it, assuming you have an activated sludge process, you would recycle your water from your aeration zone to your anoxic zone. If you don't have an activated sludge process, there are some other options including denitrifying sand filters.
