Ech2oStorm® Venturi Aerator

What is it and how does it work?

The Ech2oStorm is a static venturi aeration device installed in-line on the discharge side of a Gorman-Rupp centrifugal pump that introduces dissolved oxygen into the liquid being pumped. As the liquid moves through an internal nozzle, a drop in pressure is created known as the Venturi Effect. The Venturi Effect creates a vacuum and ambient air is drawn into the body of the EchoStorm. The air then mixes with the pumped liquid and is discharged, oxygenating the liquid.

System Benefits

With no moving parts, the Ech2oStorm is an extremely reliable device, with only routine maintenance of the Gorman-Rupp pump required. Unlike other methods of aeration, the Echo Storm is mounted on the bank of the basin, tank or lagoon allowing for easy maintenance and maneuvering of the system. The simplicity of the EchoStorm, when paired with a Gorman-Rupp pump, allows the entire system to be competitively priced compared to other aeration systems.

When offered as part of a factory-designed,-assembled and -tested ReliaSource® packaged system, the EchoStorm comes standard with a 60-month warranty* offering guaranteed reliable performance.

Municipal, Industrial and Agricultural Wastewater Treatment

Maintaining sufficient dissolved oxygen content in wastewater is key in minimizing odors and corrosion. Odors and corrosion are usually caused by a lack of dissolved oxygen in the wet well of a lift station or collection system. The available oxygen in the environment is rapidly consumed by aerobic bacteria. As a result, wastewater becomes septic and produces corrosive and odorous sulfide gases.

Gorman-Rupp's Ech2oStorm can be installed in virtually any location throughout a treatment system, and often at a lower cost to other odor and corrosion control methods. Multiple installations throughout a system promote aerobic activity from start to finish.

When installed at the headworks of a treatment plant, the EchoStorm adds oxygen to the influent, preconditioning the wastewater with dissolved oxygen, minimizing odors and corrosion throughout the remainder of the plant. Implementing a Ech2oStorm system allows grease particles to quickly rise to the surface for skimming and solids to settle to the bottom, improving primary clarifier operation.

When local regulations require a specific dissolved oxygen content within the effluent leaving the plant, a pump and Ech2oStorm can be installed at the tail end of treatment facility to ensure the discharged effluent is safe for the environment.

Gorman-Rupp's Ech2oStorm is a valuable addition to pumps and pumping stations. It is a simple, economical solution that
can be incorporated throughout the various processes of municipal wastewater treatment.

Utilizing the same municipal wastewater treatment principles, the Ech2oStorm is a cost-effective solution for adding oxygen into liquids and wastewater in a variety of industrial and agricultural applications such aerating landfill leachate and livestock wastewater lagoon systems.
