About AIR TUBE DIFFUSER

Tubular diffusers are designed to handle high volumetric air discharge ease.

Diffuser membranes are perforated to provide higher oxygen transfer efficiently.

Simultaneously, it also helps in preventing back flow.

Efficient Fine Bubble Aeration

With a 1 mm slit membrane and optimized open area ratio (28%-35%), this diffuser ensures uniform distribution of fine bubbles (<2 mm diameter), greatly enhancing oxygen transfer rates in water. This fine bubble formation is ideal for biological treatment processes in wastewater and enhances the health of aquatic environments.

Reliable Performance and Longevity

Constructed from durable EPDM rubber and ABS, the diffuser resists acids, alkalis, and wastewater contaminants. The specified service life ranges from 5 to 8 years under recommended operating conditions and cleaning protocols, making it a stable and low-maintenance choice for aeration systems.

Easy Installation and Maintenance

Designed for versatility, the diffuser supports both side and end air inlet options. Installation is straightforward-mount submerged, either horizontally or vertically, and connect via the standard 3/4" BSP male thread. Periodic backflushing and chemical cleaning maintain optimal performance and prolong operational life.

FAQ's of AIR TUBE DIFFUSER:

Q: How does the Air Tube Diffuser achieve fine bubble aeration?

A: The diffuser membrane features 1 mm slits that generate fine bubbles measuring less than 2 mm in diameter. This fine bubble formation maximizes surface area for oxygen transfer, improving aeration efficiency in water treatment and aquaculture systems.

Q: What maintenance steps are required to ensure optimal performance?

A: Regular maintenance involves periodic backflushing to clear any accumulated debris and occasional chemical cleaning to prevent fouling and maintain the anti-clogging properties of the EPDM membrane. Following these simple procedures helps sustain high performance and prolongs the unit's service life.

Q: When should I consider replacing the diffuser tube?

A: Under normal operating conditions and with proper maintenance, the diffuser typically lasts between 5 to 8 years. Replacement is recommended if you observe reduced bubble output, persistent clogging despite cleaning, or physical damage to the membrane.

Q: Where can this diffuser be installed, and in what configurations?

A: The air tube diffuser is suitable for use in sewage treatment plants, fish farming tanks, aquaculture setups, and effluent treatment plants. It is designed for submersible installation and supports both horizontal and vertical orientation for flexibility in various systems.

Q: What are the main benefits of using this aeration diffuser in water treatment applications?

A: Key benefits include high oxygen transfer efficiency, anti-clogging membrane, low energy consumption, and stable operation under challenging chemical environments. These attributes make it ideal for improving water quality and supporting biological treatment processes.

Q: How is the air supplied to the diffuser, and what is the recommended operating pressure?

A: Air is delivered via an external supply (such as an air blower) through the standard 3/4" BSP male thread connector. For optimal performance, the recommended working pressure is in the range of 0.02-0.05 MPa, with a maximum differential pressure of 0.6 bar.
