Introduction

Fine bubble air disc diffuser, which is used to transfer air with that oxygen into sewage or industrial waste water, can disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency. 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.

Disc diffuser components

Fine bubble disc diffuser includes EPDM/Silicone membrane, ABS plastic gland, ABS supported plate,rubber O-ring and check valve.

Membrane material selection

We have EPDM/Silicone membrane to choose from.

Comparison between EPDM/Silicon:

1. Price:The raw material cost of EPDM is lower than that of Silicon membrane.
2. Temperature:Silicone rubber has better temperature resistance. EPDM rubber has a temperature resistance of 150 °C, and silicone rubber has a temperature resistance of 200 °C;
3. Weather resistance:EPDM rubber has better weather resistance, and the rubber itself is environmentally friendly, also in a humid environment, EPDM rubber is less likely to breed bacteria;
4. Tear and puncture resistance:EPDM rubber is better.
5. Other:EPDM rubber has good ozone resistance and high strength; high hardness, but poor low temperature brittleness; while silicon has good elasticity and low temperature resistance; but the ozone resistance is general and the strength is low.

Suggestion:

EPDM rubber membrane

Applicable to municipal sewage, animal slaughter processing, food processing, beverage production, industrial wastewater.

Silicone membrane:

Suitable for waste water from pulp and paper industry, petrochemical and refining processing.
