Effluent Filter cleaning and replacement
The BIOROCK effluent filter should be checked annually and cleaned (rinsed) or replaced
when required.
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
The Effluent Filter should be replaced when necessary, when its condition is no longer
fit for efficient filtering of suspended solids.
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Primary Tank volume, unless superseded by local regulations.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 ask a certified septic tank emptier / licensed contractor
Check sludge level in the Primary Compartment and the Effluent Filter annually.
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, issued by the certified septic tank cleaning company, must be
retained by the owner in and kept 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.
The Primary Tank is refilled 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 project 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 m
ust leave
a few centimeters of
sludge at the bottom of the tank enabling the bacteria to continue developing
without interruption
