This storm holding tank at a plant in Ohio makes use of a jet mixer which creates a vacuum that entrains additional liquid between the inner and outer nozzles. The flow at the end of the flange shows the liquid being entrained between the inner and outer nozzles.
We made a video animation about entrainment:https://youtu.be/vfHPFcXnOWg
This flow equalization tank holds storm water at a plant in Ohio and is mixed with no air. You can distinctly see the jet plumes that mix the tank and keep solids in suspension. The liquid level varies from 5 to 25 feet.
This video demonstrates the process of mixing a holding tank in Ohio that collects wastewater during storm season. These tanks have sloped bottoms with jet mixers installed four feet from the bottom, with nozzles pointing downwards.
The system is designed to mix the tanks without air, but it has the capability to provide aeration in case issues arise with the odor in the tank (over the last twenty years, there has been no need to aerate the tank).
This 5 million gallon flow equalization tank at a plant in Ohio is designed to treat storm wastewater. The tank has a sloped bottom and uses one submersible pump on the exterior of the tank. The jet mixer has four arms which are all supplied by one 90-HP pump.
The system can be operated with the liquid below the nozzles or up to the top liquid level of the tank, as long as the liquid level above the pump is greater than 3 feet. The system shows equal liquid level distribution throughout the tank.
