Pre-Assembled Diffusers – PODS™

PRE-ASSEMBLED AERATION DIFFUSERS — OVERVIEW AND SPECIFICATIONS

Factory-assembled PODs™ diffusers come pre-mounted on lateral pipes. The assembler then connects the units as specified to create a wastewater aeration system. PODs™ size specifications include:

• Piping compatibility: Ø 3-inch, Ø 4-inch
• Retaining nut: Ø 10.7-inch
• Membrane: Ø 9-inch
• Hole size on pipe: Ø 0.67-inch
• Design airflow range: 1.5 to 3.0 SCFM
• Active surface area: 0.41 feet squared

In addition to a polypropylene retaining nut and base plate, a PODs™ system has membranes that SSI manufactures from one of four materials:

• EPDM: As SSI’s standard membrane material, EPDM offers reliability and consistency at a reasonable price point. Manufacturers use compression molding that involves vacuum technology and individual thermocouples.
• PTFE: A PTFE coating can extend the life of an EPDM membrane and increase its effectiveness. PTFE has better fouling resistance, less plasticizer loss and reduced creep.
• fEPDM™: When solvents can pose a risk to PTFE coatings, fEPDM™ membranes offer the required chemical resistance. The fEPDM™ manufacturing process also protects the membrane’s inner slits.
• Viton®: Viton® from DuPont has high resistance to most chemicals and foulants. It suits high-intensity applications in which the client doesn’t consider cost an issue.

The versatility and simplicity of PODs™ make them an excellent choice for a variety of applications.

BENEFITS OF SSI AERATION, INC. DISC DIFFUSERS

Disc diffusers from SSI serve as the foundation of PODs™ systems. SSI has extensive experience working with plasticizer to create dependable rubber membranes. A compression molding technique promotes uniformity in materials for even tear resistance. SSI disc diffusers feature advanced plastics and engineering for top-quality results.
