The AEROSTRIP® Advantage

The AEROSTRIP® fine bubble diffuser was created with the aim of achieving the lowest energy demand. The reference list covers over 20 years, including municipal and industrial wastewater treatment plants all over the globe.

Premium quality material, tried and tested design, and research-based engineering all combine to create the AEROSTRIP® fine bubble diffuser, resulting in a highly efficient product. The low profile allows the extremely durable membranes to be installed directly on the floor of an aerated tank, resulting in unbeatable full blow-in depth.

30 Years of Research & Development

The use of a 100% polyurethane membrane in combination with the strip-shaped diffuser was a revolution in aeration technique. This pioneering event was the cornerstone for the global success story of the AEROSTRIP® fine bubble diffuser family.

The advanced perforation style allows for pores of varying shape and size, which directly influence the diffuser's pressure loss. This ensures that every single membrane has the same resistance (pressure drop) to the airflow. The advantage: the membrane properties can be adapted to the specific on-site requirements.

Key Features and Benefits

  • Highest Efficiency: 400,000 pores per m² of membrane surface generate an ultra-fine bubble pattern, with an average bubble size of 1 mm. This leads to lower energy costs and optimal oxygen transfer.
  • Longevity: The unique polyurethane membrane has exceptional mechanical strength, surpassing EPDM or silicone, giving it a lifespan of up to 20 years.
  • Low Maintenance: The design prevents clogging and fouling, reducing maintenance efforts and costs.
  • Proven Performance: With over 2,500 installations worldwide, AEROSTRIP® has a proven track record of reliability and efficiency. Independent studies have confirmed its superior performance even after many years of operation.
  • Flexible Applications: The modular design allows for various layouts and configurations, suitable for different tank shapes and process requirements, including MBBR/IFAS systems.

Versatile Applications & Configurations

The AEROSTRIP® aeration system is designed for flexibility and can be adapted to a wide range of wastewater treatment scenarios.

Full Floor Coverage

For applications requiring maximum oxygen input and mixing, a full-floor coverage layout ensures even air distribution throughout the entire basin.

Grid Layout

A grid layout provides a cost-effective solution for many applications, balancing performance with capital investment. It can be tailored for various oxygen demands in different zones.

Interlinked Layout

An interlinked or 'race track' layout increases operational range and reliability, making it suitable for specific process requirements like biological nutrient removal.
