The micro-perforated disc diffuser is a membrane-type aeration device that uses ethylene propylene diene monomer (epdm) rubber as its core material. Disc diffuser efficiently oxygenates by releasing fine bubbles through micro-perforations. The base and support structure are typically made from abs or pp engineering plastics, offering both corrosion resistance and mechanical strength. Epdm rubber provides excellent aging resistance and acid-base durability, making disc diffuser suitable for long-term operation in complex water conditions.
Application of Aeration Diffuser
Municipal wastewater treatment plants:
Suitable for activated sludge processes, sbr technology, and more, meeting nitrogen and phosphorus removal requirements in urban wastewater treatment.
Industrial wastewater treatment:
Ldeal for treating high-concentration organic wastewater in industries such as chemical, pharmaceutical, and food processing, with strong resistance to acidic and alkaline corrosion.
Ecological restoration projects:
Used for river and lake water purification, working alongside biofilm technology to restore oxygen levels in water bodies.
Core Components of Aeration Diffuser
Micro fine bubble diffusers:
Tubular or disc-shaped, commonly made of epdm or silicone rubber (corrosion-resistant, anti-clogging).
Support and fixing devices:
Ensure the even distribution of diffusers at the bottom of the tank.
Control system: Flow meters, pressure gauges, valves, etc., used to adjust aeration intensity.
Blower:
Provides a stable air source, needs to match the system's airflow and pressure requirements.
Air distribution piping:
Upvc or stainless steel pipes, designed with corrosion-resistant properties.
