Mooring options and accessories.

There’s more to mooring than meets they eye. Variations in water levels can influence wastewater treatment applications and selecting the proper mooring configuration for your operations can help increase overall efficiencies.

Aerator Solutions recommends several typical mooring options to help you gain optimum efficiencies and make the best use of your EcoJet™ High-speed aerator.

Shore Mooring is the most common mooring arrangement for wastewater treatment aerators. In this configuration, the shore-end connects to an eyebolt or embedded anchor.

Restrained Mooring is most appropriate for applications with large variations in water level. This option requires the restrained mooring frame to fit loosely around the mooring posts. Allowing the aerator to slide up and down the posts, this type of positioning easily adapts to changes in water level.

Pivotal Mooring includes arm assemblies that allow the aerator to move vertically with any change in water level. This type of accessory additionally allows convenient access for maintenance, as the pivotal mooring arms can easily be pulled to the side of the tank.
