As soon as a sufficient amount of water is available in the
preliminary sedimentation chamber so that the floater is swit-
ched on during the subsequent feeding, the plant will auto-
matically switch back to the normal phase.
This adaptation to different sewage quantities is automati-
cally controlled by the control unit. The corresponding phase
is indicated on the control unit. A general overview of the per-
tinent phases and cycles is provided in chapter 2.5.
Heeding the following recommendations will help you avoid
unnecessary costs of repair and increase your plant's servi-
ce life:
• The plant must remain switched on all the time, even if you
are away on holiday.
• External water, such as rain, ground, swimming pool or fish
tank water may not be discharged into the plant.
• In the case of household detergents please pay attention
that these do not exhibit any acidic or alkaline reactions. We
recommend the use of biodegradable detergents and was-
hing agents.
• It must be possible to open the plant's covers.
• Ensure that the plant is regularly serviced by a specialised
firm.
• It is only necessary to have the preliminary sedimentation
desludged regularly (approx. every 12-24 months) by a
waste disposal contractor! After consultation with the res-
ponsible water authorities and conclusion of a maintenan-
ce contract, this can however possibly also take place in
line with demand.
Note: If the plant is taken out of operation, it must be en-
sured that it continues to remain filled.
It is imperative to note the following:
You can continue to use any detergent and washing
agent, but please adhere to the manufacturers' dosing in-
structions!
It is also possible to use various drain cleaners, provided
the dosing according to manufacturers' specifications is
adhered to.
However, every time these detergents are discharged into
the plant, a number of bacteria die off. If possible, please
make use of biodegradable detergents and dispense with
the use of drain cleaners (see 6.3).

6.2 Self-inspection by the operator

As operator of the sewage treatment plant it is your obligati-
on vis-à-vis the water authority to ensure a smooth operati-
on of the plant. Malfunctions on small biological sewage tre-
atment plants have a negative effect on the drainage quality
of the purified water. These must therefore be detected with-
out delay and rectified by yourself or by a qualified mainten-
ance firm. So as to keep a record of your self-inspections you
are obliged to keep an operations diary. At the end of this ma-
nual, you will find a master copy that contains all the neces-
sary specifications.
6. Operation and disposal
The water authority may demand to look at this operations
diary. In detail, you are requested to regularly carry out the
following inspections:
Monthly inspections
• At the control: Carrying forward the operating times on the
display into the operations diary
• At the preliminary sedimentation: inspection of the floating
sludge on the water surface. If necessary, this must be
drawn off or broken up with clear water. No sludge may
enter the aeration chamber in an uncontrolled manner. At
the latest when reaching 70% of the absorption capacity of
the sludge trap volume (= 80 cm sludge thickness) of the
sludge must be discarded. Measuring the thickness of the
sludge layer is carried out similar to measuring the oil level
on motorcars. Use the transparent sludge level measure-
ment tube. This is immersed in the pretreatment chamber
to the vessel bottom. This is plunged into the preliminary se-
dimentation chamber down to the bottom of the tank. The
measuring tool is then removed from the tank and the slud-
ge layer can be measured. An exact measurement can be
carried out by qualified personnel.
• At the aeration chamber: visual inspection of the draining
water for clearness
• Visual inspection of the mixing process and the input of air
bubbles
Six-monthly inspections
Maintenance by a specialised firm. In the process, the res-
ponsible authorities' specifications must be observed. Ap-
prox. 70% of the intake capacity has been reached at a slud-
ge height of 80 cm from the tank bottom.
