Fine Bubble Tube Air Diffuser Micro Aerators For Oxygen Transfer
Product Description
The fine bubble tube diffuser is a new type of oxygenation aerator
and the core equipment of A/O process (activated sludge
biochemistry technology). It can be applied to every position of
the sewage pool. It is featured by easy and convenient installation
and maintenance, even oxygenation and low energy consumption.

Product Feature
The tube aerator has the advantages of simple structure, high
oxygen utilization rate, reliable performance, non-clogging of
stomata, non-reverse irrigation of sewage, uniform circumferential
stress, convenient installation and maintenance, and low system
price.
It has good chemical stability, can maintain elasticity for a long
time, acid and alkali resistance, no hardening, no embrittlement,
no aging.
The self-closed pore structure is adopted, and the micropores are
not blocked. Easy installation and disassembly, reducing energy
consumption.
Product Application
Municipal and industrial waste water treatment;
Clean water treatment;
Sludge stabilization;
Wastewater ozone diffusion.
Product Maintance
1. The operator should always check the aeration status of the
aeration system. If the resistance of the aeration system increases
in the head or the shape of the bubbles changes, the aerator needs
to clean up such as carbonates, iron salts, aluminum salts and
biological sludge Such as sedimentation, scaling on the rubber
membrane of the aerator will lead to a reduction in the air output,
the oxygen utilization law of the aeration system will decrease,
and the head loss will increase.
2. Periodic drainage cleaning is the ideal maintenance method, and
the length of the period depends on the nature of the treated
water, the treatment process and other factors.
3. Pay attention not to let the sediment on the surface of the
rubber film dry and agglomerate during the drainage cleaning and
maintenance, and it needs to be cleaned immediately. The dry
agglomerates of the deposits will make cleaning work difficult,
thereby affecting the performance of the aerator.
4. Biological sludge can be removed by physical methods. Use a
brush to clean the surface of the rubber membrane or rinse it with
a high-pressure water gun. When cleaning with a high-pressure water
gun, keep the nozzle of the water gun at a distance of
approximately 500 mm from the surface of the rubber film to prevent
damage to the rubber film.
5. Scales such as carbonates should be removed chemically. A
certain amount of formic acid enters the aeration system with air.
The proportion of formic acid added depends on the degree of
scaling. It is not necessary to empty the water in the aeration
tank when cleaning. . Generally, it is cleaned once or twice a
year.
6. When the microporous aerator is damaged or the performance
requirements are not met after cleaning and maintenance, the rubber
diaphragm or the entire aerator can be replaced. The replacement
method is the same as the installation method.
