Working Principle of Diffuser Disc

Working Principle of Diffuser Disc

The diffuser disc is a highly efficient aeration device specifically designed for water treatment applications. Typically composed of a body, membrane, and connection interface, it operates by dispersing air supplied through blowers into the water via micro-perforated membranes. These micro-pores break the air into extremely fine bubbles, dramatically increasing the surface area for oxygen transfer and enhancing its dissolution into the water.
This uniform oxygen distribution creates an optimal environment for microorganisms. In wastewater treatment, diffuser discs significantly boost the activity of aerobic bacteria, accelerating the degradation of organic matter.

Application Fields

1. Municipal Wastewater Treatment:
Diffuser discs are integral to biological treatment units such as aeration and secondary sedimentation tanks in municipal wastewater plants. Their high oxygen transfer efficiency helps reduce operational costs while meeting stringent discharge standards.

2. Industrial Effluent Treatment:
In industries like chemicals, food processing, and electroplating, diffuser discs facilitate the degradation of toxic substances by providing ample oxygen, ensuring effective downstream treatment.

3. Aquaculture:
In fish and shrimp farming, maintaining dissolved oxygen levels is critical for water quality and stocking density. Diffuser discs help stabilize oxygen levels in the water, minimizing risks associated with oxygen depletion.

4. Ecological Restoration Projects:
Diffuser discs are employed in lake and river rehabilitation projects to improve oxygen levels in the water, suppress eutrophication, and restore polluted ecosystems effectively.

Future Trends

With advancements in environmental technologies, diffuser disc designs are evolving towards higher efficiency and energy savings. For instance, the adoption of advanced composite materials enhances corrosion resistance and lifespan. Additionally, smart control technologies are enabling precise adjustment of aeration rates, optimizing operations for better resource management.
