Black 13 Inch Disc Diffuser Aerator / Plate Aerator EPDM Membrane Material

Product Specification

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.
