Nitrogen removal / stripping tanks (anoxic treatment)

Introducing nitrogen-eating bacteria into the wastewater is the usual method for denitrification. Another method is to introduce a neutrally buoyant media in the tank to which the bacteria anchors itself while consuming the nitrogen. Pulsair mixing systems maintain the activated sludge, which encourages the right biological communities to form resulting in an anoxic condition suitable for denitrification. Whether the goal is to keep bacteria mixed throughout the water without increasing dissolved oxygen, or to mix activated sludge, Pulsair is well suited for either application.

Benefits of Pulsair's wastewater mixing systems for nitrogen stripping tanks:

• Thoroughly mixes bacteria without increasing dissolved oxygen
• Avoids over mixing
• Energy savings - by harnessing gravity our systems use less energy
• Programmable Operations - Programmable control options allow a facility to manage mixing functions in multiple tanks from a single point if necessary
• No moving parts inside the tank - Eliminate in-tank labor costs commonly associated with mechanical mixers
• No pumps or motors to maintain
• Simple installation - no baffles are required, and in some cases, tanks can be retrofitted without taking the tank(s) out of service
• Reduces overall operational and maintenance costs
