The excess sludge removal takes place in the series PROFESSIONAL G during the
treatment phase and in the series PROFESSIONAL XL after the follow-up time or after the
clear water evacuation.
With activated run-in phase - no sludge removal takes place (factory setting for
PROFESSIONAL G 180 days and PROFESSIONAL XL 0 days).
High-water operation
(only possible with 4 float switches, not valid for XLn)
If so much water runs into the sewage treatment plant that the maximum useful volume of
the buffer and the SBR tank is exceeded (SW2 and SW4 are closed), the alarm message
"high-water" appears and an immediate settling operation reduced to half takes place.
Economy mode
If after the last denitrification phase before settling the lower float switch in the SBR [SW1]
has not floated up, the system switches to economy mode. Here, the air supply - and thus
the energy consumption -is throttled (factory setting aeration time reduced to half).
Phosphate precipitation, UV irradiation, clear water discharge , follow-up time and sludge
removal do not take place in the eco-mode!
A settling phase is, however, carried out in the AQUA

PROFESSIONAL series.
Charging continues to take place at the set intervals even in eco-mode.
The position of the float switch [SW1] is queried in each case after the end of denitrification.
The economy mode ends with the

point where the cycle has been interrupted.
After a power failure > 30 minutes or after rebooting the control starts the cycle with the last
denitrification phase (exception with the XLA cycle; here the restart begins with the central
charging phase (i.e. with charging 5/10 with factory setting of 10 charges). Depending on the
water level in the buffer tank [SW3] with this one charging takes place.
Flushing pulses
To keep pumps free from sludge and to have a short operation during longer downtimes, the
charging, clear water, and sludge pumps are automatically switched on for the time of the
flushing pulse. This takes place in the middle of the settling phase or with each feeding
phase (independent of the position of the float switch [SW3]).
