Fine Bubble Disc Diffuser – 12-Inch Size for High-Efficiency Aeration

The 12-inch Fine Bubble Disc Diffuser is an advanced aeration device designed to deliver high oxygen transfer efficiency, optimal bubble distribution, and energy-saving performance in wastewater treatment and industrial aeration systems. With a larger surface area than the standard 9-inch model, the 12-inch diffuser offers enhanced airflow capacity, making it ideal for medium to large-scale treatment applications.

Built to meet the demands of modern water treatment technologies, this diffuser produces fine micro-bubbles that rise slowly through water, significantly increasing contact time and surface area for oxygen transfer. The result is superior oxygen transfer efficiency (OTE), which supports the effective breakdown of organic matter in aerobic treatment processes while minimizing energy consumption.

Design & Construction

The diffuser consists of a durable EPDM or silicone membrane, precision-perforated with micro-holes that generate consistent, ultra-fine air bubbles. This flexible membrane is mounted onto a reinforced PP or ABS disc base, offering excellent structural stability and chemical resistance.

The 12-inch diameter allows for broader air diffusion, making it a perfect fit for high-load systems that require reliable and even aeration over a wide area. It can be easily installed on PVC, HDPE, or stainless steel piping using standard threaded or customized connections.
