AM - SUBMERSIBLE AERATOR (MIXER)

Aerator - schéma Aerator

APPLICATION:

Aerator-mixer SIGMA is destined for effective aeration with simultaneous mixing of water, namely:

-     in aeration tanks of sewage treatment plants

-     in fish-breeding facilities – ponds, lakes, dams, basins, fish-ponds, and so on.

It is a mechanical aeration system offering both effective aeration and effective mixing. Aeration with simultaneous mixing process increase air transfer into water, disallows anaerobic processes and sedimentation of sewage at a tank bottom.


DESIGN:

This aggregate – monoblock consists of a submersible electric motor and hydraulic part, being separated from a motor unit by an oil pool and according to the aerator model, either by a mechanical seal with a shaft lip seal, or a pair of mechanical seals. Hydraulic part sucks air and even water by means of suction pipeline to reach scattering of fine-bubble dispersion of water-air in atmosphere – tanks, ponds, lakes, dams, pools ... with the aid of an impeller and a diffuser rim.


INSTALLATION:

Very fast and simple. According to the model and weight it is possible to lower the corresponding aerator-mixer and attach it to the bottom of an aeration tank with the aid of:

-       human operator by means of a lowering rope or a chain

-       lowering device (with a possibility to choose depth of submersion of the aerator-mixer)

-       manipulating mechanism (a crane)
