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.
