The reliable disk diffuser system is one of the world’s most widely-installed fine-bubble aeration systems, available in four alternative diffuser models. Preassembled diffuser elements enable fast and easy installation. Retrofits are available to increase aeration efficiency.

Main benefits
Reliable and long-lasting
Low pressure drops and therefore higher efficiency
Possibility of future increase in aeration capacity
Quick and easy installation
Flexible layout design
High temperature endurance
Suitable for aggressive wastewater

Main applications
Aeration of municipal wastewater
Aeration of industrial wastewater, with some restrictions

All diffusers have a built-in non-return valve which provides additional safety to the treatment process by preventing sludge infiltration into the aeration piping system when the air flow is interrupted. The KKI215, and PRK/PIK300 diffusers are interchangeable for retrofits, offering high flexibility.

Diffusers with EPDM rubber membrane discs:

PIK300 fine-bubble

Polypropylene main body and an antifriction ring to protect the membrane
Suitable for both continuous and non-continuous aeration processes

PRK300 fine-bubble

Strong main body, making it suitable for SBR, MBR, and MBBR processes
Antifriction ring protects the membrane
PRF300 retrofit for upgrading 215 mm diffusers to more efficient systems

KKI215 fine-bubble

Suitable for both continuous and non-continuous aeration processes
Special support for use in deep basin applications, in water up to 15 m deep

Sucoflow DS 20 fine-bubble

Ideal for high-density and retrievable aeration systems
Easy-to-fit thread connection
