Anoxic Mixers. Anoxic Mixers are used in de-nitrification basins in waste water treatment plants. The process involves the de-nitrification of waste streams through the use of bacteria which breaks down the nitrate in the waste to use as an oxygen source (energy source).

An anoxic zone is a basin, or portion of, which is mixed but not aerated. The dissolved oxygen levels must be less than 1.0 mg/L but never reach 0.0 mg/L. In an anoxic zone the bug’s oxygen source is derived from the nitrate (NO3) compounds. Nitrification and denitrification are two terms that are commonly misunderstood.

Activated sludge systems are often designed with long, narrow aeration tanks to approximate plug flow within the tank. An existing AST tank is proposed to be modified by turning the aerators off along a length of the aeration tank.

The reaction basin consisted of a steel tank with a volume of 43 m divided into influent flow, Qa =anoxic sludge recycle flow as a percentage of influent flow. This anoxic layer of sludge also plays host to unwanted anaerobic bacteria that produce hydrogen sulfide.
