9 Inch EPDM Membrane Disc Aerator Diffuser With 1 - 3 mm Fine
Bubble
Product Description
Disc Aerator Diffuser is a new type of aerator developed in recent years. The aerator
has small bubble diameter, small gas-liquid interface diameter,
large gas-liquid interface area, uniform bubble diffusion, and is
not easy to produce pore blockage, strong corrosion resistance,
improved service life, convenient installation and simple use. It
is suitable for the construction and expansion of urban sewage and
large-scale factories and the reconstruction of old aeration tank,
and the aeration tank can operate intermittently.
The gas diffusion diaphragm of the flat diaphragm aerator is made
of original quality materials, which has relatively stable physical
and chemical properties, long service life, uniform drilling, even
and small pore diameter, small bubble diameter and large gas-liquid
interface area. Therefore, it has higher mass transfer efficiency
and oxygen charging efficiency. Compared with other existing
aerators, it can effectively save power consumption and reduce
power consumption Operation cost of sewage treatment. As the
diffusion film of aeration head is made of high-quality rubber, it
has excellent physical and mechanical properties. The fittings and
air pipes are made of high-quality UPVC or ABS engineering
plastics, so it is not easy to corrode, the stability of
performance is improved, and the workload of operation and
maintenance is greatly reduced.
Product Features
1. The aeration plate is equipped with deformation resistant
strengthening structure, expanded gripping structure and anti
falling sealing bar to ensure the structural stability of the
product under high strength and long-term operation conditions and
prevent the diaphragm from falling off.
2. The thickening treatment of diaphragm coil ensures the air
tightness and reliability of the product. The thickening treatment
in the center of the diaphragm together provides the extension
compensation, resists mechanical strain and increases the service
life of the diaphragm.
3. The product is equipped with a check structure to effectively
prevent the backflow of sewage. Multiple check structures can be
added according to process requirements.
4. The vulnerable parts of the support plate are strengthened and
durable; the air flow mode is optimized to reduce the resistance
loss of the extension, and the product is efficient and
energy-saving.

Process characteristics
1. Professional membrane surface treatment process, special "I"
shaped patent drilling process from inside to outside,
Ensure that the surface is smooth, the pores are small, the product
is not easy to scale, the bubbles are small, and the air
distribution is even,
It can effectively reduce the shear damage of bubbles to activated
sludge particles and improve the biochemical activity of the
system.
2. Rubber molding technology is adopted to ensure even specific
gravity of diaphragm, multi-directional tear resistance and high
tear strength.
3. The product is assembled by plastic welding process, and the
traditional adhesive method is canceled, so the product performance
is stable and reliable.
4. It is suitable for municipal wastewater and industrial
wastewater, and can be used in SBR, cast and other intermittent
aeration processes
