Disc Diffuser features a unique spilt pattern and slit shapes, which can disperse arr 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 shutdown for air-on/air-off applications. The membrane disc diffuser can be operated over a wide range of airflows with minimum maintenance for long term performance.
Epdm can resist heat, light, oxygen, expecially ozone. Epdm is essentially non-polarity, polarity solution and chemical resistant and chemical resistant, bibulous rate is low, It has good insulating properties.
Insoluble in water any solvent, non-toxic and tastlesss, chemical properties stable, except strong alkali, hydrofluoric acid not react with any material.
