Stainless Steel Fine Bubble Disc Diffuser – High-Durability Aeration Solution

In wastewater treatment and advanced aeration systems, the Stainless Steel Fine Bubble Disc Diffuser is a premium, high-performance solution designed for efficient oxygen transfer and long-lasting operation. Engineered for heavy-duty applications, this diffuser is widely used in municipal sewage treatment plants, industrial effluent treatment facilities, aquaculture systems, and other biological treatment processes where consistent aeration is critical for promoting aerobic microbial activity.

Design & Construction

The diffuser features a robust stainless steel body paired with a durable EPDM or silicone membrane engineered with precision micro-perforations. These perforations release ultra-fine bubbles, significantly enhancing oxygen transfer efficiency (OTE) compared to conventional diffusers. The slower ascent of micro-bubbles ensures better oxygen dissolution and promotes energy-efficient aeration.

With its compact disc design, typically available in 9-inch and 12-inch sizes, the diffuser offers an optimal balance between airflow capacity, surface area, and easy installation. The stainless steel base provides exceptional mechanical strength, corrosion resistance, and the ability to withstand harsh operating environments, making it an ideal choice for long-term industrial and municipal applications.
