In the activated sludge process, the selection of aeration devices is crucial. Currently, various types of aeration devices have their own advantages and disadvantages. In response to the tendency of wastewater from papermaking, chemical industries, etc., to cause blockages, our company has launched the CZ-130 Spiral Aerator. This aerator has been introduced from Japan and has been proven effective in preventing blockages through extensive experiments and engineering practice.
CZ-130 Turbulent Aerator Introduction
1) Features of CZ-130 Turbulent Aerator:
High dissolved oxygen rate, with consistent performance without degradation throughout the year.
② No need for bottom fixing during installation, as there is no blockage, cleaning operations do not require drainage.
③Low airway resistance, saving on electricity consumption.
④Easy installation and maintenance-free
⑤ Water-resistant during installation, easy to assemble.
⑥ High oxygen dissolution efficiency;
Large service area, with each aeration head serving an area of 4-16 m³/set.
⑧ 10-year lifespan.
The working principle of the CZ-130 Turbulent Aerator: The gas emitted by the CZ Turbulent Aerator is mixed with sludge water vigorously due to strong centrifugal and impact forces, achieving the effect of oxygen being forcibly dissolved.
The working principle of the CZ-130 Turbulent Aerator's dissolved oxygen:
1) Air is discharged through a 20mm large aperture, and the air, which has a much lower density than water, will rise in the water with great momentum.
2) Due to the negative pressure inside the aeration device, approximately 1.3 times the air volume of the activated sludge water will be drawn into the aeration device.
3) The intense vortices generated by the cross plate effectively mix mud and air.
4) Air-mud is crushed into a fine particle cloud by the contactor, and oxygen is forced to dissolve into the water.
5) Water and air rise at an extremely fast speed of 1.8 meters per second, achieving uniform mixing within the trough.
CZ-130 Turbulent Aerator Installation
The CZ-130 Turbulent Aerator does not require entry into the aeration tank for operation. It can be lifted and installed as a whole, simply placed into the tank and connected to the main pipe. The release of gas, with strong momentum, rises rapidly at 1.8 m/s. The reactive force of the air flow presses the aerator against the bottom of the pool, eliminating the need for drainage and anchoring.
The installation of the CZ-130 type swirl aeration unit offers the following advantages:
1) Low number of aeration blowers
2) Few pipe joints required;
3) Low construction costs;
4) Short construction period
