6.4 Disposal
Evacuation intervals:
Unless otherwise specified, the following evacuation inter-
vals apply to the sewage sludge (from the preliminary sedi-
mentation chamber):
At 70% of the intake capacity of the small sewage treatment
plant, which corresponds to approx. 80 cm, the content of
the sludge sump must be disposed off by a waste disposal
contractor (measurement see 6.2 self-inspection of the ope-
rator or by maintenance firm).
Caution: A correct function can only be guaranteed if
the plant content is disposed of in good time.
For this reason, a disposal contract should be concluded
with an expert company.
Performing the disposal
Sewage sludge collects in the preliminary sedimentation
chamber. This sludge must be disposed of.
For taking off and replacing the duct cover use the lifting
key included in the supply.
• Take off the duct cover.
• Use the suction hose of the sewage disposal vehicle to
evacuate the sludge sump or the preliminary sedimentati-
on chamber at least until a rest of 20 cm.
• Clean the tank walls with clear water.
• Fill tank with clear water up to a height of 1.2 m.
• Clean cover bearing ring.
• Put on the duct cover.
Important information:
When disposing of the sludge trap or the preclarifying cham-
ber (in particular in the case of plant that tends to be opera-
ted below capacity), KESSEL recommends leaving about
25 to 30 cm of residual sludge in the system so that enough
nutrients can be fed to the activated sludge during the pe-
riod after disposal. If it is all disposed of, the quantity of ac-
tivated sludge will decrease due to a lack of nutrients and
the cleaning performance of the system will suffer.
We also recommend ensuring that all disposal work is car-
ried out during the summer months if possible. The drop in
the number of bacteria cultures caused by the disposal pro-
cess will reproduce more quickly during the warm summer
months than in the winter.
6. Operation and disposal
The sludge sump, the contents of which must be disposed of at regular intervals, is located on the inlet side of the tank.

Outlet
CAUTION:
The aeration chamber is located below the pipeline, which drains the sewage from the plant (outlet). The activated sludge
inside the chamber may on no account be disposed of! Pay attention that no mounting parts are damaged during the dis-
posal.
