Our FlexAir Disc, Tube, and Panel diffusers are available with the appropriate system configuration for optimized functionality.
EDI has engineered several effective configurations to fit the specific needs of our customers. Some examples of common configurations are detailed below.
FIXED GRID
When you know the right answer, you don’t need multiple choice. That’s the philosophy behind EDI Aeration fixed grid configurations: engineer the best answer once, make it easy to implement, and count on your aeration for life™.
MODULAIR
Floating retrieval lines enable the self-contained assemblies to be craned out for inspection and maintenance. Dedicated supply lines and ballasts are built right into the assemblies, as is the pipe on which diffusers are directly mounted.
STREAMLINE™
StreamLine™ is EDI’s ‘Patented’ configuration with unmatched system simplicity; results: up to 33% reduction in system installation time compared to competing panel systems. Plus, membrane replacement can be completed in the field.
FEATURES
- Superior energy savings
- Improved system reliability
- Ease of installation & maintenance
INDUSTRIAL CONFIGURATIONS
- We know you can’t just take a municipal solution and use it in all industrial applications. Industrial wastewater treatment must be specific to the wastewater effluent quality for each application. For this reason we conduct and participate in industrial testing programs and studies. This leads to the innovations in configurations and material type. Use our 45+ years of experience to your advantage and save time and money.
FIXED GRID
A fixed grid may be a common configuration, but open-heart surgery is common, too
TRUST YOUR SURGERIES TO SURGEONS…
and your fixed grid configuration to EDI’s specialized engineers who can tailor it to your specific application.
EDI fixed grid configurations are floor-mounted and ideal for concrete basins and steel tanks. Because they don’t move, they can support the highest-density applications in both municipal and industrial systems.
FIXED GRID CONFIGURATION
Advantages:

- Horizontal projected diffuser area for maximum OTE performance. System geometry supports high-density installations of over 65% (up to 80%) floor coverage
- Non-buoyant & cantilever design for reduced stress on mounting connections and for water cooling
MODULEAIR RETRIEVABLE CONFIGURATIONS
O&M made easy.
Diffusers that can be maintained when they need it make for
SYSTEMS THAT WORK EVEN AMIDST THE TOUGHEST CONDITIONS.
When accessibility for inspection and maintenance is the priority and reactors cannot be drained, the ModuleAir™ retrievable diffuser system is the solution.
Floating retrieval lines enable the self-contained assemblies to be craned out for inspection and maintenance. Dedicated supply lines and ballasts are built right into the assemblies, as is the pipe on which diffusers are directly mounted.

WHAT MODULEAIR DOES
ModuleAir makes installation into (or maintenance in) an online reactor a reality.
Where online system reliability and operating performance are mandatory, EDI ModuleAir configurations are ideal for applications. The system allows individual grids to be installed, accessed, or removed without draining or taking the reactor out of service.
This system is available in varying diameters and lengths depending on application needs. Systems up to 60 ft (18 m) and air capacities up to 2000 scfm (3400 sm3/h) have been supplied.
For tank applications, the EDI ModuleAir system rests directly on the reactor floor. The assembly is typically lifted and dropped into position with an overhead crane.
For lagoon applications, EDI ModuleAir configurations are provided with adjustable base plates. The system is typically floated and lowered into position. Adjustable base plates allow the system to be leveled from the water surface.
EDI ModuleAir is ideal for single-reactor applications where online installation and maintenance is required. The aeration system could be pullet out for maintenance without having to drain the basin. Applications requiring supplemental oxygen supply, mixing, or energy upgrades are also suitable.
Standard material of construction is stainless steel. This provides the required structural performance to support large grids. Alternate materials of construction, including galvanized steel and non-metal materials, are also available.
WHAT MODULEAIR DELIVERS
ModuleAir Systems with Lift-In/Lift-Out Diffuser Option
- Available with all EDI fine bubble diffusers.
- Accommodates variable water level and nonuniform floor conditions.
- Self-contained assembly; dedicated airline and ballasted assembly rests on reactor floor.
- Stainless steel construction standard; alternate materials of construction available.
- Retrievable modules for high rate aeration applications where the reactor cannot be drained for system maintenance.
- Modules can span 5 feet (1.5 m) up to 50 feet (15 m) depending on application.
- Typical stainless steel construction.
STREAMLINE®
The EDI-exclusive system that brings together your membrane, diffuser, and configuration for unmatched system simplicity.
STREAMLINE IS AERATION, SIMPLIFIED.
StreamLine® is EDI’s patented configuration with unmatched system simplicity; results: up to 33% reduction in system installation time compared to competing panel systems. Plus, membrane replacement can be completed in the field.
1. Minimize in-basin components
StreamLine’s proven design elevates the industry’s standard practice by minimizing in-basin aeration piping and attached diffuser components. The self-contained FlexAir® membrane panels and the inline support system reduce stress points and potential material fatigue. In short, StreamLine delivers a new level of performance, simplicity and service life.
2. Widest Application
StreamLine can be configured for any industrial or municipal application, tank size or geometry Efficient: StreamLine’s geometry supports low flux rate resulting in ultra-high OTE performance. Precision die-cut NanoPore and MicroPore perforation for meeting air handling, OTE and pressure objectives.
3. Reliable
Engineered materials for maximum chemical, temperature and UV resistance and advanced PTFE impregnated membranes for reduced fouling and optimum performance.
4. Adjustable
StreamLine provides full solids suspension both above and below the diffuser grid. Elevation of the diffuser is adjustable to match blower performance.
Unique StreamLine features and benefits:
Has a profiled top surface and no side edges, preventing coarse solids from settling on the diffuser
