General and Safety Information
With the AQUAmax®one is concerned with a technical system which, in combination with a multi-
chamber tank, is employed as small wastewater treatment plant for the aerobic biological treatment
of domestic and comparable wastewater of up to 75 PE from single or several buildings.
Dimensioning, design and operation are to take place up to 50 PE in accordance with EN 12566-3.
With employment in accordance with regulations no hazards whatsoever emanate from the plant. If
the AQUAmax®is used for other purposes without the explicit approval of ATB WATER GmbH
and/or the following safety information is ignored, this can lead to the hazarding or injury of
persons and to malfunctions or defects in the plant. In this case any liability is excluded,
Modifications to the plant or unauthorized conversion is not permitted.
The AQUAmax®and accessories are not intended to be used by persons (including children) with
limited physical, sensory or mental capabilities or due to a lack of experience and/or knowledge,
unless they are supervised by or receive instruction from a person responsible for their safety, as
to how the AQUAmax®and accessories are to be used. Children are to be supervised in order to
ensure that they do not play with them.
Before use the AQUAmax®is to be installed correctly and in agreement with the installation
instructions. Installation instructions, operating and maintenance instructions are to be read
thoroughly and the instructions included therein are to be followed implicitly.
With assembly and installation, commissioning and operation as well as, if required,
decommissioning, national standard specifications and regulations are to be complied with. All
tasks may be carried out by trained and qualified specialists with appropriate certificate of technical
qualification. The operator is to be instructed by the fitter.
With the connection of the control system the national applicable regulations and the details on the
type plate are to be complied with (mains voltage, frequency etc.). The equipment is to be operated
on a network which includes a protective earth conductor (PE). Attention is to be paid to correct
phase connection (even with plug-in design)! The connection to the mains must take place by
means of separate fusing and residual current protective circuit breaker. Before commissioning,
the correct function of the electrical protective measures must be checked!
The installation work is to be carried out by qualified electricians only. With work on the equipment
fundamentally the mains plug is to be disconnected. A separation or extension of the cable is not
permitted. The electrical connection data is to be taken from the type plate on the equipment.
Operate no equipment which has a damaged connector/connection cable or plug, which indicates
a malfunction, has been dropped or has been damaged in any way.
With all maintenance and repair work the plant is to be disconnected from the mains. The
AQUAmax®can be removed easily from the tank. If the plant is to be climbed into, this may take
place only with the presence of a second person (this is fundamental!). Particular care is to be
taken. The applicable accident prevention regulations and rules of technology are to be complied
with.
In the versions with submersible aerator the AQUAmax®feeds the required air to the wastewater
through a rapidly rotating propeller. Never work in the vicinity of the aerator as long as the
AQUAmax®is connected with the mains. Danger of injury!
The correct function can only be guaranteed with the employment of original spare parts or spare
parts approved by ATB. Before commissioning, all points of the operating instructions are to be
checked. Keep these instructions readily to hand at all times!

Functional Description
The wastewater treatment plant works according to the activated sludge principle using the
retention process (single tank or SBR plant). With this, the contaminants from the wastewater are
taken up by suspended micro-organisms (activated sludge) and converted into biomass.
The wastewater first reaches the coarse interceptor. Every 2 hours – according to the principle of a
communicating pipe and with the aid of an excess sludge pump – the retained wastewater is fed
into the aeration stage. The aeration takes place intermittently via a submersible motor aerator or
with a compressor and membrane tube diffusers on the tank bottom (CLASSIC ZB).
After 6 hours the aeration phase ends and the settling phase begins.
After 2 hours settling time the treated wastewater is pumped out using the clarified water pump.
The switch-off point is determined via a float switch. If, as a result of a pump defect, this minimum
water level is not achieved an alarm is triggered. After ca. 8 hours, with the end of the clarified
water removal, the cycle is ended and a new one begins.
The control unit can be matched to the respective requirement case. With commissioning the plant
is set to the maximum number of persons connected. A modification of this setting is not required
with short-term over or underloading.
The plant achieves its full treatment performance after a run-up period of ca. one month. With more
extreme underloading or temperatures under 12° C it can also take longer until the biology has
developed completely. In this case it is recommended to seed using activated sludge in order to
accelerate matters.
With the AQUAmax®BASIC charging, removal of excess sludge and the drawing off of clarified
water take place using only one pump. The water streams with this are fed into the individual areas
using a patented hydraulic system.

Holiday / energy-saving operation
If, over a period of more than 4 hours, no wastewater flows into the plant, then the system switches
automatically into the energy-saving holiday operation. The aeration time is reduced to the point
that the micro-organisms just have sufficient oxygen available. With normal loading the plant
switches back into the operating mode set.
Sampling
As the pumping out process is of a short duration only, the treated water is collected into a suitable
container in the filtering tank (accessory: 1.5 l sampling bottle). The container is mounted in the
vicinity of the cover and is thus easily accessible from above.
Alternatively a container can be deployed in a separate sampling shaft.
Installation and dimensioning
Dimensioning and statutory installation conditions are described in more detail in the German
National General Technical Approval.
Operation and maintenance
Small wastewater treatment plants must be checked by the operator at certain intervals as well as
being serviced twice a year by a specialist. Both are important for a correct operation of the plant.
The sludge removal of the primary settling stage takes place, depending on utilisation, once a year
or as required.
Further details on this can be taken from the corresponding chapter.
Application possibilities
The AQUAmax®is conceived for the treatment of domestic wastewater. The following may not be
fed to the small wastewater treatment: commercial/trade wastewater (insofar as it is not
comparable with domestic), infiltration water (e.g. drainage water), cooling water, runoff water from
swimming pools, precipitation water.
Technical data
The AQUAmax®consists of the following electrical units:
•1 (BASIC) or 2 submersible pump(s)
•1 or 2 submersible motor aerator(s)
or compressor(s)
•1 float switch (BASIC and CLASSIC 1-16
integrated)
•1 control unit
The units are designed for 230V, 50 Hz.
In addition, the AQUAmax®consists of a carrier frame, pipelines and hoses.
The electrical components are subjected to systematic wear. In individual cases these components
must be exchanged after 2 years. The service life of the units, from experience, lies between 5 and
10 years.
Treatment performance
The AQUAmax®meets the following limiting values (with standard conditions and correct
operation):
•BOD5: 20 mg/l
•COD: 90 mg/l
•NH4N (>12°C): 10 mg/l
•N
tot: 25 mg/l (>12°C)

Test run
In test run operation the current float level and the current power input are
indicated. Pressing OK carries out the test run.
With this make absolutely sure that no one is working in the danger area of the
running submerged aerator!
The individual units are taken into operation for 4 seconds and are checked for overload and/or
underload. If the minimum permitted value is undercut or the maximum permitted value is
exceeded a warning signal results.
By manual switching of the float switch (BASIC / CLASSIC: submerging in or removing from the
water) the test run can be repeated and concluded.
AQUAmax®BASIC and CLASSIC are equipped with the AQUAswitch©. With this you are
concerned with a reed contact switch, which is integrated in the air intake line. The actual
float body cannot be seen from outside. For switching, the AQUAmax®has to be

Error Messages
"Current min" The minimum permitted current of the respective unit is undercut for
longer than 5 seconds following switching OFF of the unit. The
value of the current, which is measured, is saved as environmental
condition.
"Current max" The maximum permitted current of the respective unit is exceeded
for longer than 5 seconds following switching ON of the Unit. The
value of the current, which is measured, is saved as environmental
condition.
"Flooding" A flooding alarm is identified as, despite the maximum, activation
time of the clarified water pump, no change of the float has been
identified.
"Float supply" For the measurement of the float level, the float is supplied with a
separate voltage, which is used for diagnosis. An error “Float
supply” leads to the generation of a default value “Float up”, i.e. the
processes run in normal mode with cyclical flooding alarm as
pseudo error.
UVS®(Under Voltage Signalling / Voltage failure detection)
The UVS®simplifies the safeguarding of an efficient operation. If there is a power failure (supply
voltage < 100 V), e.g. through the activation of the residual current circuit breaker (RCCB) or a
fuse, an acoustic alarm is initiated. The pulse tone continues, depending on the charged status of
the accumulator, for up to 24 hrs. The signal is deactivated by pressing any key or as soon as a
sufficiently high voltage is generated. Adjustments do not have to be undertaken. A power failure is
recorded in the logbook.

USB Connection
You have the possibility of reading the logbook data via the USB connection (e.g. using USB stick).
For this, open the control unit and insert the USB stick in the socket provided.
ATTENTION! Voltage carrying component. Implementation by qualified personnel
only!
If the unit is ready there is an acoustic signal. The info window must be visible in the display.
Press the ▲and OK keys simultaneously. A renewed acoustic signal
indicates the successful transfer of data. The data can be read subsequently
as an Excel file.
Fuses
The control system has three socketed insert fuses of the TR5 type. The fuses can be exchange
using needle-nosed pliers.
Should an exchange of fuses be necessary the control unit MUST be disconnected
from the mains beforehand!
