Effluent Filter cleaning and replacement
The BIOROCK® effluent filter does not need to be cleaned.
We advise you to replace it when the Primary tank is emptied, or when the filter is clogged,
or after two years.
Open the cover at the PVC pipe that provides access to the Effluent Filter
Take the rod holding the Effluent Filter and lift it carefully to remove
Beware of flying particles
Emptying of the Primary Tank
The first emptying of the Primary Tank takes place, when the sludge level reaches 50% of the
Primary Tank volume, unless superseded by local regulations.
Always use a certified septic tank emptier.
Replace the Effluent Filter at least every two years.
The frequency with which the tank is emptied may be adapted according to the nature of the
operation and how many people live in the building. It must be emptied when the sludge level
reaches 50%.
The cleaning certificate, written by the certified septic tank cleaning company, must be retained
by the owner in and placed in the maintenance guide.
The septic tank emptier should pressure wash the sides of the tank and the Effluent Filter to
remove the accumulated fats and other matter.
The tanker, while emptying the Primary Tank, must not be parked any nearer than 4 meters (14’)
from the installation to ensure and maintain stability.
Refill the Primary Tank with clean water after emptying before resuming normal operation.
Further information:
The quantity of sludge produced is influenced by how the unit is used (size, frequent overloads, type of waste
water, routine maintenance). Each unit is different.
We estimate that an installation of 5 PE will produce a maximum of +/- 900 liters of sludge in the first year.
The quantity of sludge produced will reduce over the first few years: normally after the fourth or fifth year,
the residual quantities will have decreased by 40%. When emptying, the cleaner must leave a few centimeters of
sludge at the bottom of the tank; the bacteria that break down the sludge are specific and take a long time to
develop.
