WASTEWATER TREATMENT 

PLANT MODEL AT6 - AT50

Important points of control:
Solids bag

 – cannot be clogged. Remove non-degradable materials.

Operation of airlift 1

 – mixing in the solids bag. The flow should not be too strong or too weak. 

The flow generated by airlift must be sufficient for efficient agitation.

Aeration work

 – air bubbles appearing on the surface of the aeration chamber during blower 

operation must be fine.

Operation of airlift 2

 – this airlift pumps the settled sludge from the secondary settler into the 

non-aerated and aeration chamber. Pumping of the sludge mixture must always take place dur

-

ing the operation of the blower.

Operation of airlift 3

 – internal recirculation in the non-aerated (anaerobic) chamber. Pumping 

of the sludge mixture must always take place during the operation of the blower.

• OPERATION AND MAINTENANCE INSTRUCTIONS

Launching the Unit:

• Setting the BASIC controller 
• Connecting the blower
• Adjusting the air distribution manifold valves 
•  Filling  activated  sludge  (0.25  m3-4  m3,  depending  on  sewage  treatment  plant  model  and 
sludge concentration)

Unit shutdown:

The Unit is turned off upon disconnecting the controller. Make sure to pump out the contents of 
the Unit, wash and fill it up with clean water.

The list of necessary maintenance tasks:

The Unit operates automatically and requires no continuous maintenance, but the owner should 
periodically perform the inspection and maintenance.
