Submersible Mixers Wastewater

Frequently Asked Questions

Will the introduction of large bubbles increase the dissolved oxygen level?

Answer:  No, the large pulses of compressed air are too big and pass through the liquid too fast for any meaningful transfer of oxygen to take place.  See the attached report from the New York City Department of Environmental Services NYC SS anoxic performance report summary


How many pulse points or accumulator plates do I need in my tank?

Answer:  The number of accumulator plates or pulse points is determined based on the tank geometry and the type of liquids in the wastewater treatment process being mixed.


Can I retrofit an existing tank basin?

Answer: Yes, Pulsair mixing systems can be installed in new construction or in existing tank basins.  Once the system is installed, there is zero in-tank maintenance.  This is a huge advantage to wastewater treatment operators and allow them to maximize tank utilization, eliminate tank downtime and help streamline the entire wastewater treatment process


How does it compare to submersible impeller mixers?

Answer: Pulsair is in a sense a submersible mixer in itself but drastically differs from mechanical impeller mixers because the mixing process starts on bottom of the tank to push and pull solids to the surface and create immediate vertical circulation pattern in the tank.  Submersible impeller blade mixers only push liquids inefficiently and laterally across the tank floor resulting in accumulated solids building up.


What are the advantages of this mixing process over traditional mixing methods?

Answer: The main advantages of the Pulsair large bubble mixing process for wastewater treatment are but not limited to:

  1. Zero in-tank maintenance
  2. 100% homogeneous mixing at any liquid level
  3. Faster mixer than mechanical mixers
  4. Adjustable speed & power setting to maximize energy efficiency
  5. Suspend solids and sludge to keep tank floors clean
  6. Custom engineered for any size
