Sewage Treatment Plant Blowers
One of the main methods of wastewater treatment is a biological approach. This method is based on the destruction of organic compounds by bacteria in aerobic conditions. The bacteria are nurtured in aeration tanks (usually rectangular).
In this reservoir, air is pumped into the wastewater. Air-saturated sewage is the ideal environment for the development of specific aerobic bacteria.
There are various means of sewage air saturation in the aeration tank. For this purpose, Bioxica uses different types of blowers such as:
- vortex,
- rotational,
- variable pressure.
Appropriate selection of blowers is the key to future savings and highly efficient production.
In each case, Bioxica selects the types and parameters of the blowers and manufacturers, based not only on the calculations, but also on professional experience.

Vortex blowers are devices of dynamic action that are designed to discharge air. In these blowers, there are no wearable parts except bearings. Vortex blowers are able to work in compression and vacuum modes. The rotor of BL series blowers is mounted directly on the motor shaft for noncontact compression. As there are no friction pairs in the working area, there is no wear. Bearings are located outside of the compression zone, and therefore they are hardly exposed to heat from the compressed air, hence their life is higher than that of models having bearings in the area exposed to excessive heat.
Air is sucked into the working area at point 1, and then passes through the working channel 2 through a helical path and leaves at point 4. Moving along the path, the air is affected by centrifugal forces and tangential forces generated by the impact of blades of the impeller.
At point 4, the air flow collides with the razor, which overlaps a half-section of the path, so the air is directed to the outlet.
All BL series blowers are equipped with an integrated silencer for outlet and inlet pipes.
Rotary blowers are used for oil-free air compression. The blowers have a two-trident rotor arranged in parallel, which rotates within the housing and acts as a piston. Rotors are connected by a synchronous transmission. Non-contact run eliminates the need for lubrication of the rotor.
Rotary blower
Rotary Blower includes 5 main parts:
- Housing;
- 2 bearing compartments;
- Two covers.
The housing is a cylinder, where the air moves under the influence of rotors, from the point of suction to the point of displacement, where it is compressed. Bearing compartments are located on both sides of the body cylinder; there is oil in the compartments which is used for lubrication of shaft axis and gearing. Special seals do not allow the oil to penetrate into the body, rotor landing slots, and synchronous transmission zone.
Depending on the depth of the aeration tank, low or high pressure blowers are used.
Low pressure blowers
Low pressure blowers are used in aeration tanks of average depth.

High pressure blowers
High-pressure blowers provide the higher pressure necessary in aeration tanks with a depth greater average, but in comparison to the low-pressure blowers, they have a smaller air volume.
