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 AQUA
max
®
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 AQUA
max
®
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 AQUA
max
®
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.
