5.1

Sludge removal

Sludge removal is to be carried out at the latest when the sludge level has risen to 70 %.
5.2

Cleaning the ANAEROBIX FILTER

The ANAEROBIX filter should be checked regularly for blockages or backups. If necessary, the bags with
the carrier material are to be removed from the filter and cleaned. We recommend cleaning the carrier
material with a water hosepipe.
In accordance with DIN 4261-1 all chambers / tanks are to be aerated. If necessary, additional ventilation
lines or ventilation openings are to be arranged. The ventilation lines are to be positioned in such a way
that natural ventilation is possible (flue effect).
