Disc Micro Bubble Diffuser With High Quality For Municipal Sewage
Features:
1. 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%.
2. 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.
3. Excellent counterflow prevention function
The back stops are all equipped with valves to avoid counterflow when the air transmission is
broken off, enabling the pores to shut smoothly and applicable to intermittent operation. Its
unique and even air vents can lead the airflow effectively, and can prevent sewage water from
flowing into the aerator pipeline effectively.
Product Description
The reinforced EPDM can continuously create fine bubble from slots on the EPDM membrane
of disc type or tube type diffuser. The expected duty life may be over 5 years without tearing
or bursting. There are other material selections of self-sink silicon rubber membrane, ceramic
diffuser, air stone, and coil looking diffuser. There are also course bubble air diffuser for
application of liquid mixture. The diffuser can be used for roots blower, ring blower and linear
air pump. The diffuser also has advantage of much energy reduction.
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.
