Product Q&A

Q:What is the main function of the aeration disc?

It provides oxygenation by dissolving air into water for aerobic microorganisms and mixes sludge, wastewater, and air thoroughly to ensure uniform contact.

Q:What is the lifespan of an aeration disc?

Under normal urban wastewater conditions, EPDM membranes last 5-8 years. Lifespan depends on water quality, operating time, maintenance, and air quality.

Q:What are the differences between EPDM and silicone membranes?

EPDM is cost-effective and resists municipal wastewater chemicals but not oils. Silicone resists oils/hydrocarbons, is more flexible, and lasts longer but is more expensive, suitable for industrial wastewater.

Q:How does the diffuser prevent hole blockage?

The micro-holes automatically expand when air flows in and close when air supply stops, which prevents the holes from being blocked by sludge or debris.

Q:Is the product customizable?

Yes, customization is available for Material (EPDM/Silicone), Color (Black/Blue), Membrane Thickness, and Service Life based on specific project needs.
