Functional description PUROO®
The wastewater treatment plant functions according to the activated sludge principle in the
impounding process (SBR process). With this the pollutants are taken out of the wastewater by
floating micro-organisms (activated sludge) and converted into biomass.
The wastewater first reaches the coarse interceptor, which is connected with the biological stage
through an opening in the dividing wall. The undissolved matter settles in the coarse interceptor
before the pretreated water reaches the aeration stage through an overflow baffle. The opening in
the dividing wall causes the water level in the complete plant to be set at the same level. Thus the
complete surface area of the plant is used as buffer.
The cyclic treatment process of the plant is controlled by water level. With an average water
consumption, 1-3 cycles per day take place. A floating valve placed in the aeration stage directs
the air either to the aeration facility (membrane tube aerators are at the bottom of the tank) or to
the higher located compressed air elevator.
With low water level, the aeration stage is stirred and aerated by the input air. Following
appropriate water inflow the valve switches with a defined water level HWmax to the compressed air
elevator for the conveyance of the water. The compressed air elevator is connected to a
combination vessel (recirculation, sampling).
The switching of the valve is registered by a level switch, through which the settling phase is
initiated. The first flush with the conveyance is retained by the combination vessel and is fed into
the primary treatment as sludge return feed.
During the 60 minute settling phase further conveyance surges for sludge recirculation can take
place depending on the system.
Following the ending of the settling phase the compressed air elevator is again cleaned through
several short conveying surges using treated wastewater before the actual clean water removal is
applied. With the removal of clean water, the water level is lowered to the minimum water level

HWmin defined via the floating valve, and the float valve is switched again to aeration. This is again
registered by the level switch.
In case the minimum water level cannot be achieved within a preset time, an alarm is activated and
the program changes into emergency operation in which, within ca. 1 hour, a shortened program
sequence takes place.
The pretreated wastewater which is transferred to the biological stage during the clean water
removal is fed into the lower area of the tank in which the sedimented activated sludge is located.
There, at this point in time, treatment processes are already taking place under anoxic conditions.
Through the special arrangement of the overflow baffle a situation is achieved whereby the
wastewater flowing in has no influence on the quality of the treated water in the clean water zone.
Regulation can be adjusted to the respective requirement. With commissioning the plant is set to
the maximum number of connected persons. A change of this setting is not necessary with short-
term over- or underloading.
If no or only so little water flows in over a period of more than 48 hours following a removal of
clean water that the plant remains below the maximum water level, the plant goes into economic
mode. The aeration time is reduced such that the micro-organisms have sufficient oxygen
available to survive. With renewed rise of the water level to the maximum water level the plant to
normal operation following removal of the clean water.

Functional description PUROO®Complete
The wastewater treatment plant functions according to the activated sludge principle in the
impounding process (SBR process). With this the pollutants are taken out of the wastewater by
floating micro-organisms (activated sludge) and converted into biomass.
The wastewater reaches the first of at least two chambers. The chambers are connected by
openings in the dividing wall. This ensures that the water level is the same throughout the plant.
The total surface of the plant is used as a buffer. All chambers are aerated.
The cyclic treatment process of the plant is controlled by water level. With an average water
consumption, 1-3 cycles per day take place. A floating valve placed in the aeration stage directs
the air either to the aeration facility (membrane tube aerators are at the bottom of the tank) or to
the higher located compressed air elevator.

During the clear water discharge, treated waste water flows from the front area of the tank into the
last chamber and on to the suction area of the compressed air elevator. Any sludge contained will
settle again on the way to the suction area of the air lifter and has no influence on the discharge
quality.
With the removal of clean water, the water level is lowered to the minimum water level HWmin
defined via the floating valve, and the float valve is switched again to aeration. This is again
registered by the level switch. In case the minimum water level cannot be achieved within a preset

returns to normal operation after clear water discharge.

General notes on operation
The operation of the control unit takes place via three short-stroke keys. By pressing a key the
display lighting is switched on (lapses if no key is actuated within 5 minutes).
Key functions:
↑↓ Scroll up and down / menu selection
OK Switch the cursor to the figure, which is to be changed / input value is saved / select menu
point / menu setback.
With temperatures below 0°C severely limited function of the LC displays is to be reckoned with.
Assembly of the atbControl®1 control unit
The control unit is already assembled prefabricated in the control cabinet for wall-mounting or in
the open-air cabinet.
Only the power plug has to be plugged into a prepared isolated ground receptacle (wall mounting)
or the feeder connected to the designated isolated ground receptacle in the open-air cabinet.
Plug in the power plug of the compressor and of the float switch into the appropriate sockets on the
control unit.
CAUTION! Before opening the control unit this must be disconnected from the
mains supply. Work on opened equipment may be carried out exclusively by
qualified skilled electricians!
As one is concerned with electrical plant it is essential that a separate B16
fuse and a (separate) 30 mA upstream earth leakage circuit breaker (ELCB)
are provided!
Attention is to be paid to the correct laying of the protective earth conductor up to
the earthing of the building.

Commissioning
Basic settings are carried with the first commissioning. With the input of plant values all important
parameters are preset. However, we recommend to check the parameters und Settings once again
following commissioning.
Select the desired language for the menu management display using the OK
and ↑↓ keys and confirm with OK. The following languages are available:
German, English, French, Spanish, Swedish and Dutch.
Through the input of an access code it is ensured that the commissioning is
carried out by a specialist.
Enter the six-figure code number using OK and ↑↓ and confirm with OK.
Enter the date (Indicator = DD.MM.YY) and time (Indicator =
HH:MM:SS) using OK and ↑↓ and confirm with OK. Important for
the correct inputs in the logbook.
Select the PUROO®plant type using OK and ↑↓ keys.
Select the plant values using OK and ↑↓ and confirm with OK
(important for the selection of preset parameters)! The
parameters for 20 and 24 PT are to be taken from the table on
Page 16 and are to be entered manually.
Using OK and ↑↓ enter the serial number which can be found on the
PUROO®(not that of the control unit!) and confirm each number with OK.
Please note that the serial number is to be entered right-aligned.
Have you made an incorrect input? Commissioning can be repeated by
selecting NO and OK.
If the inputs are correct confirm with YES and OK.
Changeover to the info indicator follows. Displayed are the selected PT
number, the software version, time and serial number of the PUROO®.
With this the commissioning is completed and the PUROO®can start working. Should, in the

Should a power failure occur in the supply line, e.g. through the activation of the earth leakage
circuit breaker (ELCB) or a fuse, an acoustic alarm is initiated. Once activated the impulse tone,
depending on the charge condition of the accumulator, continues for up to 24 hours. You
acknowledge the alarm by pressing the OK key (signal tone) for ca. 3 secs. If the voltage is re-
established the signal deactivates automatically.

1) For standard conditions. These values can vary in practice by +/- 10%.
2) Depending on the frequency of desludging (see page 20 Aeration settings).
Setting of the control system takes place according to the above details. The tables are saved in
the control unit, a manual input of the individual values is not necessary and at these points serves
only as control.
