    CENTROX AERATOR FUCHS METHOD

 

 

Applications
FUCHS Centrox aerators are used to introduce oxygen into aerated lagoons, equilization basins, activated sludge plants and aerobic digestors. In addition to a fine bubble aeration, they also provide for the circulation and thorough mixing of the substrate to be treated.
They operate with optimal reliability and require practically no maintenance.

 



1. Technical description :

FUCHS Centrox aerator consists in : an air-cooled, vertically mounted motor a suction pipe coaxial to the drive shaft the impeller at the immersed end a diffuser on request, the electric motor is provided with a protective housing
Advantages :
calm water surface no water spray no odours no or few putting in suspension of the decanted matters
Principle :
the rotating hollow agitator sucks in the liquid from underneath and the air through the suction pipe from above, swirls both components and then centrifuges the mixture along the diffuser radially to all sides. The aeration takes place with fine bubbles with a high transfer efficiency and a calm surface water. As there is no sprayed or splashed water, there are no problems with odour and cooling-off during wintertime. Besides the noise level of CENTROX aerators is so low that they can be installed close to residential areas.

2. Installation
In circular or square basins, CENTROX aerators have to be installed in the middle. In case of large or rectangular basins, a higher quantity of such machines has to be arranged equidistantly on the surface. With constant water level they can be mounted with brackets to walkways.

If very deep basins have to be aerated and mixed, an additional draft tube has to be placed under the machine.
On lagoons or in equalizing basins, the CENTROX aerators have to be mounted on flotations, which consist in a frame with flotation tanks, supports and mounting fittings. The frame is a hot-dip galvanized, welded steel construction. The flotation tanks are made of GRP and filled with polyurethane foam. The supports are made in stainless steel like all immersed or small parts.

3. Technical data

The Centrox aerator exists in 11 versions from 0,75 kW to 18,5 kW.
