PRODUCT SPECIFICATION SHEET EDI Nautilus® Floatable Aeration Module “Float-In / Float – Out” aeration modules offer installation and maintenance flexibility without draining the reactor*. • Economical solution where retrievable aeration components are desired • Supports high density diffuser designs for maximum operating efficiency and aeration capacity. • Ideal for large reactors, single basin systems, or when inadequate access is available • Configurable with fine or coarse bubble diffusers • Simple access and inspection; single valve activates integral buoyancy chamber and raises the assembly to the water surface • Nautilus II configuration provides full access to the diffuser assemblies allowing maintenance to be completed in place • Simple maintenance; relocate floating assembly to reactor perimeter for removal or maintain in place with Nautilus II configuration *All aeration systems regardless of type need to be designed with access in mind. EDI Nautilus system is an economical solution when; operating a single reactor system, components cannot be accessed due to large reactor size, restricted access around perimeter of reactor, when the facility is near or at capacity, or basin cannot be drained for any reason. • Configurable with fine or coarse bubble diffusers www.wastewater.com Environmental Dynamics Inc.

PRODUCT SPECIFICATION SHEET Draining reactor basins to access, inspect or maintain aeration systems is a significant outage and results in a disruption in service. EDI Nautilus® “float-in / float-out” aeration module allows aeration components to be accessed and removed from the reactor with no interruption in service or requirement to drain the reactor basin. Individual modules are self-ballasted and are independently retrievable. Single valve activates an integral buoyancy chamber and lifts the assembly to the water surface. The floating assembly is easily relocated to the reactor perimeter...
