High Efficiency Fine Bubble Disc Diffuser Strengthened PP Glass Fiber Support
New design fine bubble disc diffuser with high efficiency
High oxygen nano bubble diffuser features a unique split pattern and slit shapes, which can disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency.
A much highly effective and integrated check valve enables the aeration zones to be easily shut down for air-on/air-off applications.

Features
Standard Membrane Materials
We provide disc diffusers that are specially designed for a plethora of applications.
The special low plasticizer EPDM is aimed at beverage production, and food and animal processing. The silicone membrane diffuser is specifically created for refining processes, petrochemicals, and the paper industry.
Anti-fouling Surface for Membrane Materials
Relatively based on the latest nano technology, the surface of the membrane materials are meant to prevent the accumulation of both biological and solid encrustations.
Reinforced Polypropylene Support Dish and Ring
We provide disc diffusers with rings and support dishes that are strengthened and well-protected by glass fibers for optimum chemical resistance. With this sturdy support dish, it can endure varying temperatures and resist harmful UV rays.
All disc diffusers come with built-in non-return valves to ensure safety and security of the water treatment process. This valve controls the build-up of sludge and prevents its infiltration into the aeration system, especially when the airflow is sporadic.
