Jet aerators have been used in tanks with 13 to 65 ft (4 to 20 meters) liquid depth. In deep tanks, due to the hydrostatic pressure of the bubbles, the initial and average bubble size is smaller than in shallow tanks. Smaller bubbles result in high mass transfer due to the following reasons:

  • Higher surface area in the tank volume.
  • The bubble stays in the tank longer due to the lower velocity of the rise.
  • Higher pressure in the bubbles produce a greater driving force for oxygen transfer.

Mixing in deep tanks is provided from the bottom of the tank to the top. For this reason, jet aerators are not limited to just shallow tanks. The jet aerators provide maximum mixing near the bottom of the tank.

All aeration and mixing occur below the surface so there is no mist or spray problems. In addition, no icing problems occur because the aeration and mixing units eliminate thermal stratification, thus preventing freezing.

A jet aeration system by Mixing Systems, Inc. consists of quality components that have an established reputation for reliability.

  • Materials of construction are durable and resistant to abrasion, corrosion, and ultraviolet light.
  • The jet nozzles used by Mixing Systems, Inc. have no moving parts that can wear out and no small passages to clog.
  • Pumps and blowers are normally placed outside the tanks where they can be easily serviced.

In addition, the system is designed and manufactured to minimize field installation labor. Jet assemblies and piping are typically fiberglass which is lightweight, adaptable and easily installed.
