Tube Diffusers

What Makes SSI’s Tube Diffusers a Global Choice?

SSI tube diffusers are ideal in wastewater aeration applications. Each design offers a unique way to produce bubbles that optimize the oxygen transfer rate so more microbes can grow during activated sludge treatment.

Tube diffusers produce small bubbles with substantial active surface areas. Smaller, more active bubbles take longer to rise, and many sink to the bottom of the tank. The result is thorough aeration above and below the air source.

SSI’s designs reduce labor costs and manufacturing timelines, facilitating competitive prices and lead times. Additionally, SSI is able to produce various types of tube diffusers at different sizes. Custom designs are available as well. There is a tube diffuser for any aeration tank, and SSI helps clients choose the best option.

Types of Tube Diffusers

Tube diffusers install inside aeration tanks and deliver oxygen through a thin nozzle, causing bubbles to form. The bubbles facilitate the growth of microorganisms that consume organic material during the activated sludge treatment process. There are various types of tube diffusers featuring different materials and configurations.

SSI Tube Diffusers are available in  (PTFE)and a variety of other membrane materials all designed to resist clogging and fouling. These diffusers are affordable due to cost-efficient production methods and materials. They are easy to install with Snappy Saddle™ or standard nipple mounts.

Fine Bubble Tube Diffusers

SSI’s fine bubble tube diffusers feature advanced membrane materials that yield high standard oxygen transfer efficiency (SOTE). Materials include (PTFE) coated ethylene propylene diene terpolymer (EPDM), standard EPDM, silicone and polyurethane (PE).

SSI’s fine bubble tubes feature a patented channel-pipe support that provides an unobstructed pathway to the end of the diffuser when the membrane is inflated, enabling uniform bubble production.

Snappy Saddle™ Diffusers

SSI’s Snappy Saddle diffusers offer simple installation and advanced efficiency. The single-seal design expedites installation and reduces the risk of leakage by 50%. It only takes one technician to install a Snappy Saddle diffuser.

Nipple Tube Diffusers

SSI’s nipple type tube diffusers feature a single narrow orifice which is ideal in low-pressure systems. Using a narrow end increases pressure as air passes through, allowing the system to produce smaller bubbles without increasing energy consumption.

ECT Diffusers

An ECT tube diffuser will provide high SOTE with minimal pressure loss. SSI develops ECT diffusers by molding the plastic housing around the membrane rather than shaping, clamping or gluing the device together. This manufacturing choice produces competitive quality at a 75% lower cost. Membrane material options include EPDM, PTFE and silicone.
