DN350mm EPDM Membrane Disc Aerator Diffuser With Fine Bubble
Product Description
350mm Disc Aerator Diffuser has 6 stiffeners plus circular stiffeners, the product is solid and durable. The device has small aeration bubble, large gas-liquid area, uniform bubble diffusion, no hole blockage and strong corrosion resistance. When the aerator is aerated with oxygen, several air supply tanks are designed on the main panel, so that the incoming air can be buffered by the check valve and then directly sent to the center of the aerator head to ensure that the diaphragm can be opened easily at one time with low resistance.
The diaphragm is mechanically assembled with rib anti lock to ensure that the diaphragm is not easy to fall off. During air intake, the micropores on the air distribution membrane expand by themselves to ensure air passing through. When the aeration is stopped, the variable micropores on the gas distribution membrane are closed. Because the variable micropores on the gas distribution membrane expand and contract by themselves, the micropores passing through the aerator are not blocked. Secondly, the bottom plate of the aerator is provided with a check valve device to prevent the mixed liquid from entering the gas distribution branch pipe when the gas supply of the pipeline system is stopped, so as to prevent the mixed liquid from entering the branch pipe and being blocked. The air entering does not need special filtration, and the intermittent aeration is not blocked. A great technical improvement has been made to the phenomenon that the air distribution membrane is easy to blow and tear, and the membrane cannot be opened or blocked.
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. Low diaphragm resistance, easy to open, low power loss
2. Smooth surface, sludge easy to fall off
3. Large aeration service area
4. The diaphragm has sufficient extension
5. Mechanical assembly, good sealing performance
6. Solid overall strength, long service life
