Venturi-Aerators aeration systems

The ‘bank-mounted’ Venturi-Aerators are designed to minimise risks associated with the aeration of ponds and lagoons without reducing performance.

During maintenance and servicing, surface-mounted aerators need to be accessed via floating walkways or some kind of vessel, which require operators to work over water. Alternatively, the aeration devices may need to be lifted out by the use of cranes or other lifting apparatus.

Venturi-Aerators are powered by Gorman-Rupp self-priming centrifugal pumps, so they can be mounted on the banks of the lagoons. This means that operators can perform all required servicing and maintenance without having to work over water, work at heights or work with heavy swinging weights.

The bank-mounted aerators have been tested to produce as much as 1.86 kg/kW of oxygen transferred per kW per hour.

Maintenance of the units is simple and convenient so minor issues can be addressed before they become problems. With no moving parts in the aerator, one operator can safely adjust clearances in minutes and check and adjust seal and bearing oil levels quickly and easily.
