AEROSTRIP® Fine Bubble Diffusers
Efficient, Long-Lasting Fine Bubble Aeration
Hydroflux Epco, as a long-standing partner of AquaConsult and the exclusive Australian distributor of AEROSTRIP® Fine Bubble Diffusers, has been delivering innovative aeration technologies to Water Authorities and Councils for over a decade. Many of Australia’s largest wastewater treatment plants already benefiting from AEROSTRIP fine bubble diffusers — over 60km of AEROSTRIP Diffusers successfully operating in Australia since 2008 and more than 2,500 installations worldwide since 1995.

The two key advantages of AEROSTRIP fine bubble diffusers are substantial energy savings, thanks to their high oxygen transfer efficiency of 4.0-5.0 kgO2/kW, and the durability of their polyurethane membranes, which consistently exceed a lifespan of 12 years minimum. The AEROSTRIP Diffusers are suitable for use in conventional municipal activated sludge plants, sequential biological reactors, membrane bioreactors and virtually any aerobic wastewater treatment process.
Why AEROSTRIP Fine Bubble Diffusers Are the Ultimate Choice for Municipal Applications
AEROSTRIP is the most trusted fine bubble diffuser in Australia, favoured by all major Water Authorities and Councils. Combining premium-quality materials, a proven design, and research-based engineering, the AEROSTRIP fine bubble diffuser delivers high-efficiency performance.
Key Benefits Include:
- High Oxygen Transfer Efficiency 4.0-6.0 kgO2/kW reduces energy consumption
- Ultra-fine bubble size maximises oxygen transfer rates, achieving efficiencies of up to 60%
- Durable polyurethane membranes exceed a 12-year lifespan, significantly outlasting conventional membranes
- Non-clogging design ensures reliable operation with minimal maintenance
- Greater floor coverage with the low-profile strip design, allowing installation directly at the tank base
- Suitable for high MLSS reactors (MBR) operating at >15,000 mg/L
- Multiple lengths and configurations allow for installation in any tank shape or size
- Intermittent or continuous operation options for process flexibility
- Documented proof of efficiency and durability
Various AEROSTRIP Fine Bubble Models Available for Any Application
Materials of construction
The AEROSTRIP main body can be supplied in durable PVC or corrosion-proof stainless steel.
| Feature | Type Q | Type T |
|---|---|---|
| Body Material | PVC | Stainless Steel AISI 316 |
| Membrane Materials | Polyurethane | Polyurethane |
| Air Connection | PVC | Stainless Steel AISI 316 |
| Clips | PVC | Stainless Steel AISI 316 |
| Length | 1.0 – 4.0 m in 0.5 m steps | 1.0 – 4.0 m in 0.5 m steps |
| Height | 50 mm | 20 mm |
Perforation Options for Different Applications
The polyurethane membrane is perforated with needle holes to allow the supplied air to exit the diffuser body. The type of perforation has a significant impact on the operating range, i.e. the air flow rate of the aerator. With AEROSTRIP fine bubble diffusers you can choose between different types of perforation.
The “STANDARD” perforation has slightly smaller holes but a higher number of holes (approx. 400,000 holes/m²). It is particularly suitable for operation with low to medium-specific airflows and achieves very high values for oxygen uptake (SOTE) and oxygen yield (SAE).
The “PHOENIX” perforation has slightly larger holes but a smaller number of holes (approx. 133,000 holes/m²). This results in a lower pressure loss and allows an efficient working range with specific airflows above 40 Nm³/h per m² of membrane area.

Exceptional Quality Control
Every single AEROSTRIP membrane and diffuser undergoes rigorous testing at the factory in Austria before delivery to ourselves and our customers.
The diffusers are assembled by skilled personnel using semi-automated assembly lines and are certified to ISO 9001 standards. Each individual AEROSTRIP polyurethane membrane is thoroughly tested prior to assembly through various methods, including FTIR spectroscopy for material inspection, tensile testing to determine material constants, and stereo-microscope inspection for accurate visual checks. Additionally, all AEROSTRIP diffusers are tested under the same flux conditions to ensure they meet high standards for leakage, bubble pattern, size, and uniformity.
