Fine Bubble Diffusers

Fine bubble diffuser membranes come in various materials to meet wastewater treatment system needs. SSI Aeration offers the following diffuser membrane types.

PTFE-Coated Membranes

PTFE surfaces protect diffuser membranes from substances that can damage conventional membrane elastomers and shorten their lifespans. SSI’s PTFE membranes are made of synthetic rubbers that are highly resistant to solvents, chemicals, grease and fats.

PTFE membranes are resistant to fouling and require less frequent cleaning than other membranes. PTFE surfaces serve as barriers that prevent shrinking, hardening, plasticizer extraction and swelling. The benefits of PTFE significantly reduce long-term power costs and increase the diffuser’s ability to distribute air evenly across the system’s floor.

EPDM Rubber

EPDM rubber’s low plasticizer content extends its life span — EPDM membranes last longer before breaking, hardening or shrinking. Their elongation at break and tensile strength are much higher than industry standards, making them significantly resistant to tearing. It can stretch up to 700% of its resting span, which prevents it from deforming over time.

SSI creates its EPDM membranes by using high-quality injection molding machines. These membranes produce outstanding results, including:

• Superior longevity and oxygen transfer efficiency.
• Reliable performance with minimal shrinkage.
• Head loss mitigation to enhance productivity and efficiency.
• Anti-static properties for the production of very fine bubbles and increased fouling resistance.
• Cost-effective membranes that help lower costs.

FEPDM™ Membranes

SSI Aeration’s EPDM™ membranes are highly resistant to chemicals. A FEPDM™ membrane’s high chemical resistance protects it from intensive solvents present in some wastewater. FEPDM™ protects a membrane’s entire outer surface area and inner slits, comprehensively boosting the membrane’s resilience when faced with intensive solvents.

Viton® Material Membranes

Viton® is one of the most resistant membrane materials — like SSI’s FEPDM™ membranes, it has a high resistance to most chemicals and foulants. A Viton® material membrane is an excellent choice for wastewater plants with a high budget.

Silicone Membranes

Silicone-coated membranes are ideal for wastewater treatment systems with ozone issues, high temperatures or a preference for inorganic membrane materials. Silicone membranes can withstand temperatures up to 315 degrees Celsius.

Polyurethane Membranes

SSI Aeration, Inc.’s high-strength polyurethane membranes’ robust characteristics make them useful for various industrial applications where durability and longevity are necessary.

SSI Aeration offers bubble diffusers in various sizes:

• 7-inch fine bubble disc diffuser: SSI’s 7-inch fine bubble disc diffuser can fit PVC, PP, CPVC and stainless steel pipes.
• 9-inch fine bubble disc diffuser: The 9-inch fine bubble disc diffusers are highly efficient and durable. They can fit PVC and stainless steel and attach using pre-assembled PODS, grommets or saddles.
• 12-inch fine bubble disc diffuser: 12-inch fine bubble disc diffusers are larger to accommodate larger active surface areas.
• 20-inch fine bubble disc diffuser: The 20-inch fine bubble disc diffusers can meet the needs of wastewater treatment systems with larger loads and demands.
• 2-inch tube diffuser: SSI’s 2-inch tube diffuser is 62 millimeters and comes in either nipple type or snappy saddle varieties.
• 3-inch tube diffuser: The 3-inch variety of tube diffusers are 91 millimeters and also available as a snappy saddle or nipple type.

Bubble diffusers are made with different materials and function in different ways. The different types of bubble diffusers include fine bubble plate diffusers, fine bubble disc diffusers and fine bubble tube diffusers.

The primary wastewater treatment phase uses physical processes to remove solid waste from wastewater. The secondary wastewater treatment phase is a biological process that uses beneficial microorganisms to break down more solid wastewater impurities. Aeration is a crucial part of the secondary water treatment phase, feeding microorganisms the oxygen that allows them to metabolize organic matter in the water.

During the secondary wastewater treatment phase, aeration tanks push oxygen into diffusers with small openings on their surface. These openings create small bubbles as they come into contact with the water in the aeration tank. The bubbles that a diffuser produces feed oxygen to microorganisms in the tank. Feeding the bacteria in the tank helps them produce enzymes to break down organic matter faster.

Adding oxygen to the tank also mixes the wastewater and keeps solids suspended, preventing excess sludge buildup. After the waste breaks down, it settles into the secondary clarifiers or a settling tank. As the biosolids combine, they create a sludge that the wastewater treatment plant can then pump back into the aeration tank to introduce new microorganisms that can break down more waste.

Since the aeration process can account for anywhere from 30% to 70% of a plant’s total energy consumption, it’s crucial to have the right equipment for wastewater treatment. Having the right aeration equipment can reduce energy consumption and lower costs. Fine bubble aeration diffusers deliver more oxygen to microorganisms while using less power, making them an energy-efficient option.

Industries worldwide prefer SSI Aeration Inc.’s fine bubble diffusers because of their:

• Durability: SSI’s filter membranes avoid leaks at startup thanks to their patented single-molding technology. Fewer leaks provide a prolonged membrane life to ensure the facility’s system works according to its demands and schedule.
• Efficiency: SSI’s fine bubble diffusers feature a uniform bubble pattern from side to side and end to end. This pattern creates an environment with high oxygen-transfer efficiency that more evenly breaks down waste.
• Sizing: Finding the right product size is crucial for a wastewater facility’s needs. SSI’s fine bubble diffusers are small enough to avoid breakage from extreme cantilever and large enough to save money on installation and piping.
• Affordability: The durability, efficiency and accurate sizing of SSI Aeration, Inc.’s fine bubble diffusers combine to create an affordable solution. They allow facilities to spend less on repairs and replacements, avoid the need for extra piping pieces and reduce operating costs over time from increased efficiency.
• Quality: SSI’s high-quality fine bubble diffusers provide peace of mind. They reliably provide the desired results, even when working as part of an existing system.
• SSI Aeration, Inc.’s services: Buying SSI Aeration, Inc.’s fine bubble diffusers gives clients more than a durable, efficient and affordable product. They also receive specialty services that increase the value of their fine bubble diffusers, like pre-sale system design services that ensure the most satisfactory results. They also receive support and service after the sale, providing long-lasting peace of mind and quality assurance.
