9 Inch Coarse Aerated Water Fine Bubble Disc Membrane Air Diffusers
Product Description
EPDM air bubble diffuser, which is used to transfer air and with that oxygen into sewage or
industrial wastewater. Oxygen is required by microorganisms in the water to break down the
pollutants. Fine bubble diffusers produce a plethora of very small air bubbles which rise slowly
from the floor of a wastewater treatment plant or sewage treatment plant aeration tank and
provide substantial and efficient mass transfer of oxygen to the water. The oxygen, combined
with the food source, sewage, allows the bacteria to produce enzymes which help break down
the waste so that it can settle in the secondary clarifiers or be filtered by membranes.
Features:
1. Long guaranteed life
EPDM membrane is a special elastomeric polymer with high non-deformability and anti-
tearing index. The membrane is made at even thickness with small pressure. Special
processing technology is used to overspread 6000 micro-pores on the surface of the
membrane. Under running condition the air bubbles rise with spiral whirlpool, giving self-
purification ability to the membrane. The life of the membrane under normal use is guaranteed
for 5 years, but usually it is necessary to use it together with the water removal system.
2. Unique ring seal
The aeration head tightening ring provides tight sealing effect between the aeration head base
and the membrane washer -- the higher the air pressure, the better the sealing effect.
3. Easy installation
PVC soft connector can be installed directly without any other auxiliary tools. The operation is
easy and convenient.
Finds Application In :
1. Aeration for SBR reaction basin, contact oxidation pond, and activated sludge aeration
basin in sewage disposal plant;
2. Aeration for denitrification / dephosphorization aerobic processes;
3. Aeration for excreta and animal wastewater treatment plant;
4. Aeration of deep aeration basin;
5. Aeration for high concentration wastewater aeration basin, and aeration for regulating pond
of wastewater treatment plant;
6. Aeration of fishpond and other applications.
