General and Safety Information
With the AQUAmax
®
one is concerned with a technical system which, in combination with a multichamber 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.
