13 Inch Plate Type EPDM Membrane Fine Bubble Disc Diffuser In Black
Product Description
350mm Disc Aerator Diffuser is 40% lower than that of fixed spiral aerator, diffused aerator
and perforated pipe aerator, or the sewage treatment capacity is
increased by 40%. It is especially 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.
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
Product Features
1. Structure for preventing reflux
When the air is closed, the center of the membrane falls on the
orifice of the membrane tray, and the non-perforated area can cover
the air release orifice, similar to a check valve, to prevent
liquid from flowing back into the aeration system. In addition,
according to the characteristics of sewage treatment process, an
independent check valve has been developed, which can be used in
combination with diaphragm check
2. Special punching technology
Mechanical punching technology, there’re over 5,500 perforations in
Dn200 aerator, over 6,300 perforations in Dn215 aerator, over 9,000
perforations in Dn260 aerator,over 10,000 perforations in Dn330
aerator. Air deflector diameter is 0.5cm, the contact space with
the membrane is 0.15cm, which make the opening rate of the membrane
can reach 99.9% .At the same time, it can improve oxygenation
capacity and oxygen utilization rate and reduce ventilation
resistance.
3. Compact structure and uniform gas distribution
A folded-concave structure with better sealing performance is
adopted between the membrane and the bottom plate, which solves the
disadvantage that the aeration membrane is easy to fall off when
the air flow is too large. At the same time, a guide ring and six
air guide grooves are added to the chassis support. Compared with
other existing aeration devices, under the same operating load, the
required aeration volume is greatly reduced, and the aeration is
evenly distributed throughout the tank.
4. High pressure injection molding machine injection molding
The professional machine is shaped by many processes, refined and
cast, controlling every process and creating the perfect product.
5. The rubber content of our membrane is higher.So it has stronger
tear resistance .In addition,its support frame is made of
reinforced pp.So it has a longer service life.
