Pre-Assembled Diffusers – PODS™

PODs™ pre-assembled aeration diffusers save time and have a low margin of error. They suit situations that require a fast installation or collaboration with a contractor. Learn more about SSI’s exclusive PODs™ diffuser systems and their benefits.

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.
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.
