We recommend evaluating the following factors before finalizing the membrane material:

Wastewater composition and chemical exposure.
Expected operating temperature.
Continuous or intermittent aeration requirements.
Membrane flexibility and fatigue resistance.
Cleaning chemicals and cleaning procedures.
Expected maintenance intervals.
Replacement availability and lifecycle cost.
A manufacturer should provide material details and application-specific recommendations rather than relying only on general material descriptions.

Fine Bubble Diffuser Technical Specification Table

The following table provides a practical checklist for evaluating diffuser products. The numerical dimensions are illustrative examples of commonly encountered configurations, not universal requirements or specifications for a particular Titan Aeration model.

Parameter
Typical information to review
Diffuser type
Disc, tube, panel, or specialized membrane design
Nominal diameter
Common disc formats include approximately 200 mm and 270 mm
Tube length
Model-specific; confirm active membrane length
Membrane material
EPDM, silicone, or another compatible elastomer
Support material
Polymer, engineered plastic, or corrosion-resistant material
Airflow capacity
Manufacturer-defined minimum, preferred, and maximum rates
Pressure loss
Manufacturer-tested value at a stated airflow
Connection size
Confirm the actual fitting and thread specification
Bubble characteristics
Test data or manufacturer-defined performance description
Oxygen transfer
SOTR and SOTE under specified test conditions
Operating temperature
Manufacturer-defined material and operating limits
Chemical compatibility
Confirm against the wastewater and cleaning chemicals
Installation method
Approved mounting arrangement and orientation
Maintenance
Inspection, cleaning, and membrane replacement requirements
Service life
Application-dependent estimate supported by operating conditions
For procurement, the final specification should include actual model numbers, dimensional drawings, tested performance curves, connection details, and the manufacturer’s installation requirements.
