7 inch 8 inch 9 inch epdm silicon bubble diffuser membrane disc air
fine bubble aeration diffuser
Fine bubble diffuser, which is used to transfer air and with that
oxygen into sewage or industrial wastewater. Oxygen is required by
microorganisms in the water to break down the pollutants. Fine
bubble disc diffuser series combines effective design, low
installation costs, reliability and high performance in
intermittent and continuous aeration processes.Special designed the
slits cut opining, patterns and spacing between the slits for high
oxygen transfer and longtime operation.

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 dish 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 air flow is sporadic.
♦ Quick and Easy Installation
We offer disc diffusers that include pre-fabricated components for
easy and fast installation process. In case replacement or
maintenance is necessary, the materials can also be removed easily.
♦ Flexible Design
The disc diffuser has an adjustable pipe support system for easy
leveling during the installation process. It also fits onto any
type of material, which includes ABS, PVC, etc.
♦ Full Pipework System
For minimal issues on the installation and removal process, the
disc diffuser boasts fully operational pipework system for
enhancing growth and expansion in the long run.
