Small Sewage Treatment Equipment Fine Bubble Disc Diffuser For Waste Water Treatment Plant 

Features:

High Oxygen Transmission Efficiency (OTE)

The pores on the EPDM membrane are almost 100% even, tinyair bubbles of 1-3mm are formed (the air bubbles are petty and even with good flow velocity and fluid condition), and the contact area with the sewage water is increased, so the oxygen transmission efficiency is high. Under the best ventilation capacity, the average oxygen transmission efficiency for every meter of water depth is up to more than 6%.

Good effect on saving in power, and low operating cost
Because of the high oxygen transmission efficiency, low powered blower can satisfy the oxygen volume required by aeration process. As a result, power is saved, operating cost is decreased, and the cost is reduced.

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.

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.

Moisture purge system:

The temperature of the air will become very high after compressed by the blower of the blast aeration system (usually up to 50- 90), and the water vapor and oil component in the hot air will condense and cumulate in the aerator pipeline. The water removal system can discharge the condensed water in the aerator pipeline and the waste water that has entered the pipeline through aerator when the blower shuts down, and avoid blockage of micro-pores.
