Self-Inspection By The Operator - Kessel InnoClean PLUS Instructions De Montage

As soon as a sufficient amount of water is available in the
preliminary sedimentation chamber so that the floater is
switched on during the subsequent feeding, the plant will
automatically 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 pertinent 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 ser-
vice 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
washing 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 re-
sponsible water authorities and conclusion of a mainten-
ance 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
instructions!
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 di-
spense 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 obliga-
tion vis-à-vis the water authority to ensure a smooth opera-
tion of the plant. Malfunctions on small biological sewage
treatment plants have a negative effect on the drainage qua-
lity of the purified water. These must therefore be detected
without delay and rectified by yourself or by a qualified
maintenance firm. So as to keep a record of your self-ins-
pections you are obliged to keep an operations diary. In
chapter 13 (operations diary) of these operating instructions
you will find a master copy that contains all the necessary
6. Operation and disposal
specifications.
Checks must be carried out at the intervals specified in the
operations diary (chapter 13). Deviations must be docu-
mented and forwarded to the maintenance partner respon-
sible in order to guarantee operational safety. An explanati-
on of faults and how to eliminate these can be found in
chapter 9 of these operating instructions.
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 mea-
surement tube. This is immersed in the pretreatment
chamber to the vessel bottom. This is plunged into the
preliminary sedimentation chamber down to the bottom
of the tank. The measuring tool is then removed from the
tank and the sludge 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
sludge height of 80 cm from the tank bottom.
