Description of functions
The wastewater treatment plant works based on the activated sludge principle in the
backwater procedure (SBR plant). In this procedure the pollutants are removed from the
wastewater by floating microorganisms, the activated sludge, collected and converted into
biomass.
The water then enters the preliminary treatment stage/coarse trap. From the preliminary
treatment stage the backwater is fed into the activation stage every 2 hours by means of a
filling tube (communicating tubes). The pump only runs for a few seconds for this process.
Aeration is provided intermittently by a submerged aerator. Part of the air is collected in the
air collection tray affixed under the clear water pump and fed into the filling tube.
This interrupts the communicating tubes.
The surplus sludge is returned by filling pulses of the sludge pump at the beginning of the
aeration phase. The duration of the filling pulses is dependent on the values saved in the
control. Once the aeration phase is complete, the resting phase begins.
After the resting phase, the treated water is fed out through the clear water pump. There is
also the option of routing the treated water through a sampling unit. The cut-out point for
the clear water pump is determined by the float switch. If this minimum water level cannot
be reached, a high water alarm will be triggered. The complete cycle takes 8 hours.
Then a new cycle begins.
The plant is controlled electronically and can be adjusted to suit the requirements of the
situation at hand. The motors' runtimes are shown in the display and documented in the
control's memory. During commissioning the plant is set to the maximum connected
population total. It is not necessary to change the setting for temporary overloads
/ underloads.
If no wastewater enters the plant for a longer period of time, the system switches itself to
eco-mode automatically. The aeration time is reduced to the point where the microorganisms
have sufficient oxygen.
When normal loads return, the plant switches back to the previously set operating mode.
Cleaning capacity
When operated correctly and in optimal conditions the AQUATO wastewater treatment plant
can produce results below the legal limits.
Effluent class “D” package
The control has an expanded programme module.
The additional package offers the possibility of increasing the cleaning capacity.
An additional anoxic treatment phase, so-called denitrification, can reduce N to a
total
value of less than 25 mg/l (>12°C).
Sampling
As the pumping-out procedure only lasts a short time, part of the treated wastewater is
collected in a suitable recipient (accessories: 1.5 l sampling bottle). The recipient should be
positioned in the area of the cover and be easily accessible from above. Alternatively, it is
also possible to attach a separate sampling shaft.

Preparation for assembly
Separating wall between sludge storage and activation basin
Emergency
spillway
Tank preparation using a 3-chamber tank with two quarter-
chambers for the preliminary treatment (sludge storage and buffer)
and one half chamber for activation (biology) as an example.
- All dimensions must be verified at the installation site.
- The accident prevention regulations must be observed.
- The tank must be installed at the correct height and be waterproof. It is must be subjected
to and successfully pass a leakage test in accordance with DIN 4261.
- The tank should contain no wastewater and be clean. All of the tank's chambers must be
accessible for persons (opening min. 60 cm).
- The lid of the tank must have aeration holes and a separate aeration tube must be
installed. The tank must be sufficiently ventilated.
st
- The inlet must lead into the 1 quarter-chamber.
- Both quarter-chambers should be connected together below the water level.
- The separating wall between the half-chamber and both quarter-chambers must be
waterproof.
- An emergency spillway must be created in the area of the separating wall between the two
quarter-chambers and the half-chamber (e.g., by means of a notch).
- In two-chamber tanks, a scum board must be placed in front of the emergency spillway in
pre-treatment phase (e.g., made of PE). This prevents scum from entering the activation
phase.
- The discharge tube is connected to the shaft and extends around 15 cm into the shaft
(do not cut off at the level of the shaft).
- An empty conduit of at least DN 100 mm must be laid between the location of the control
and the tank. It must not contain include any bends > 30°. A pulling wire should be
planned into the empty conduit. The cable conduit must later be sealed off to prevent
odours from escaping.
- The location of the control device is supplied with electricity at 230 V and the following
individual fuse protection: B 16 A and residual current circuit breaker 25 A / 30 mA.
- The maximal cable length between the control and the treatment plant must not exceed
35 m.

Installation instructions
Preparation of the AQUATO
Before inserting the AQUATO into the treatment tank, take the required minimum water
level in the SBR basin for the planned population total from the “General technical
approval”.
Determine the exact height of the separating wall. Subtract the measurement of the
minimum water level from this height. The remaining measurement is the setting for the
AQUATO.
If the setting is correct, the cut-off point for the float switch is now exactly the same as the
minimal water level .
Unit for chain installation
Here the dividing wall bracket is not
applicable. The threaded bar - inserted top
horizontaly into the guide - is provided with an
ring lug on both ends. By means of shackles,
hooks and chains - 2 x 1.5 m long – the unit
is suspended at a appropriate height.
Minimum waterlevel is the bottom edge of the
pump carrier (see picture above)

Unit for dividing wall installation
The dividing wall bracket with carrier tube is innitely adjustable in the pump carrier
with low effort. You can position the required setting dimension exactly (lower seating
edge dividing wall bracket to lower edge of pump carrier, see picture). With narrow
dividing walls (up to 75mm), take the small contact surface as a base, with wider divi-
ding walls (up to 125mm), take the large contact surface as a base. As an additional
alignment against torsion, a vertical line runs along the tube, which has to be aligned
to the V-groove of the metal plate.
On the back of the pump carrier, 3 self-
cutting screws are pre-bolted. (In transport
position, the middle screw is tightened,
please loosen for extraction / twisting).
These 3 screws are now onward screwed
into the side wall of the carrying tube and
x the plastic carrying tube in the carrying
frame.
Note: Do not tighten the 3 screws with
a large lever stroke, in order to prevent
overtightening.

Installation instructions
Inserting the AQUATO
When assembling on a separating wall (tank with 2 or 3 chambers), the AQUATO is placed
on the separating wall. Caution!: The dividing wall edges have to be rounded off. When
assembling in a tank without a separating wall, the AQUATO is fastened in the upper part
of the tank, e.g., on the cone / flat lid, with screw hooks.
The submerged tube with the filling tube must be
nd
inserted in the 2 preliminary treatment stage. If
there is only one preliminary treatment stage, a
scum board (e.g., made of PE) must be placed in the
area of the submerged tube to protect against scum.
For chain systems, the filling tube must not sag (no
formation of impasses); it must curve upwards so
that an air pocket forms at its highest point, which
separates the communicating tubes.
The supplied short discharge pipe is connected to
the clear water tube with a coupling connection and
inserted approximately 50cm into the tank discharge,
where it is fixed in place to avoid it slipping out (see
also Sampling possibility). The unpressurised clear
water outflow must be guaranteed.
Affix the “WARNING BIOLOGY” sign.
- a holder, which is inserted in the tank in such a
way that it poses no hindrance to the installation /
removal of AQUATO and it is still possible to
remove the bottle easily.
- a special lid for the sampling bottle with the
possibility to connect to the 25 mm clear water
tube.
- PE wide-necked 1,500 ml bottle as a sampling
bottle.
Cable connections
Route the control cables of the AQUATO through the empty conduit to the control.
Standard cable length 15 m (optionally available from 15 m to 35 m in 5 m increments).
Insert the special plug in the control's socket and screw tightly.
The control device must not be connected to the mains yet!
The operating instructions must be observed before connecting to the mains.
Before commissioning the plant, fill the preliminary
treatment stages and the biology with water up to the
top part .
Sampling possibility
An integrated sampling possibility is foreseen. Our available model is composed of:
