    FUCHS CENTROX AERATOR WITH FOAM CONTROL


 

1. General

FUCHS Centrox aerators are mainly used to transfer oxygen in equalization tanks and plants for the aerobic treatment of sewage sludge or liquid manure. In addition to a fine bubble aeration, they also circulate and then mix the substrate which is to be treated. Foam arising from aeration can flow back into the intake cone. Thus the foam level is controlled.

The Centrox aerator with foam reduction conception is simple and robust, it operates with optimal reliability and is practically maintenance-free.

2. Description

FUCHS Centrox aerator with foam reduction consists in : an air-cooled vertically mounted motor an intake cone coaxial to the drive shaft an impeller at the immersed end The electric motor and the intake cone are mounted to the framework of the flotation. They are a structural unit. For fixed installation, the electric motor and the intake cone are mounted to the same base plate. On request, the electric motor is provided with a protective housing.

 

 3. Principle

The rotating impeller sucks-in the liquid from underneath and air or foam through the intake cone from above, swirls these components and then centrifuges the mixture radially to all sides. The aeration takes place with fine bubbles and high oxygen utilisation, i.e. problems with sprayed or splashed water, cooling-off during wintertime or odours are, in all probability, avoided.

 

4. Installation
  in ring, square basins in the middle of the basin
