Nozzle Aerator


Product Description

The nozzle aerator is a development for the oxygen supply in aeration tanks. By using this system, energy savings can be achieved because the usual membrane resistance of the current commonly used aerator is no longer incurred. Design-related advantages is another result of the permantent forced emptying of the nozzle aerator. For cleaning purposes, e.g. by feeding  , acetic acid of the nozzle holder is backwashed during operation so that calcification or clogging is permanently avoided.

Through an offset arrangement of nozzle aerators and fluid nozzle carriers, the essential circulation or inoculation of the wastewater can also be implemented in the activated sludge tank. Due to the fluid nozzle carriers, a more even mixing of the pelvic volume with reduced energy consumption can be achieved. The fluid nozzle carriers with project-related Di ≥ 1mm have a similar design and also have permantent forced emptying. Backwashing is realized via connectable hose systems.
