260mm Plate Type EPDM Membrane Disc Aerator Diffuser In Black
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.
EPDM membrane is suitable for municipal sewage, industrial
wastewater from animal slaughtering, food processing and beverage
production; silicone membrane is suitable for industrial wastewater
from pulp and paper industry, petrochemical industry, refining and
processing, etc.
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
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
