The DDI retrievable aeration grid system is designed with the diffusers mounted on structural frames which can be lifted out of the basin for waste inspection and maintenance without having to disrupt the wastewater treatment process.

The removable grid system is a cost-efficient alternative to constructing a parallel treatment train plus many wastewater treatment plants cannot meet their effluent regulation requirements with a tank temporarily out of service.

Our systems can be designed for either crane or winch liftable and are suited for either Disc or Tube diffusers.
