ABS Disc Diffuser System

A reliable solution for efficient oxygen transfer

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

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

PRK300 fine-bubble

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

KKI215 fine-bubble

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

Sucoflow DS 20 fine-bubble

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