Aeration disc ECD270 was installed in Wuhan Zhucheng on June 15, 2024

2024-06-18

This project uses 1580 ECD270-E

The ECD270 consists of a membrane, a support disc, and a saddle connecting part. When oxygenation

and aeration, compressed air is diffused into the water through the microporous air cloth layer to achieve

the purpose of oxygenation and aeration.

EPDM is a synthetic rubber product developed according to the customer's usage requirements. Due to its unique compound composition and compression moulding process, the membrane retains its physical properties for long periods of time under minimal water pressure, resists tearing, and retains its shape after years of cyclic operation, producing fine air bubbles. Our EPDM membrane products have been tried and tested in a variety of municipal and industrial wastewater treatment applications with excellent results. However,

standard EPDM is not recommended for applications where solvents, grease, or oils are present, as well as high concentrations of metal salts. Manufactured using a compression moulding process with uniform specific gravity and thickness. Resistant to pulling in various directions and to changes in the properties of the diaphragm material. High coefficient of elasticity, proper taper can reduce unit pressure, low pressure loss, high dissolved oxygen efficiency, long service life. The centre area of the diaphragm is non-porous and the diaphragm will fall back to the base and seal when the aeration system is shut down. The entire diaphragm surface allows good air passage. Membrane resists clogging and is at least 70% hydrophilic. Tear elongation of up to 700% is suitable for processes with cyclic opening and closing operations and retains its shape over long periods of time, producing fine air bubbles. The diaphragm material is high quality EPDM rubber with less than 12% oil content. The characteristics are as follows (attached table):
