4. Clearwater extraction
and sludge return
1. Charging phase
• Wastewater flows into the
1. chamber
• In portions into SBR tank
(2. chamber)
• Activation of the micro-
organisms
• Settlement of the sludge
at the bottom
• Outflow of the cleaned water
• Returning of the sludge into
the 1. chamber

2. Settle phase
3. Discharge phase
1. Aeration phase
• Raw sewage enters pre
treatment phase
• Directly undergoes aerobic
purification
• Activated sludge settles to
the bottom
• Clear water zone forms in
the upper part
• Incoming raw sewege is
retained by the dividing wall
• Purified water is removed
by means of a
compressed air lift
