Microporous Membrane Diffuser Disc uses ABS engineering plastics as the main body and is covered with special rubber EPDM or silicone, which is anti-adhesion because of special processing. The CNC cutter imported from Germany ensures the quality and precision of the holes. When the disc is filled with air, four air supply slots ensure the incoming air to be directly sent to the central aerator with low resistance. The membrane is specially assembled to ensure never fall-off.
The micro holes will automatically expand while the air incomes and close while no air comes, which avoids the blocking of the holes. A check valve is specially installed to prevent the mixture from entering the pipe and blocking the pipe. The incoming air does not need special filtration and intermittent supply of air does not block the holes and pipes. The Diffuser Disc could diffuse air evenly with high efficiency
Applicable to biological waste water treatment and conventional industrial waste water treatment, the working temperature could reach 176 ℃.
The working temperature range could be -65℃ to 232 ℃, which is suitable for waste water such as pulp and paper industry, petrochemical and refining process.
