16.3 Production of sludge:
Important
The de-sludging of the Tricel
Duos system is the responsibility of the homeowner
De-sludging should never be carried out alone.
Do not allow equipment drive over the plant. Maintain a distance of at least 4 meters away from the covers
on the Tricel Duos plant.
The access cover should never be left off an unattended plant
The Tricel Duos plant must be desludged periodically but a maximum every 3 years. The two chambers
either side of the aeration chamber must be emptied and refilled with water. De-sludging is done with a
vacuum tanker (we recommend the use of a licensed company).
16.3.1 De-sludging (emptying the solid waste from the chambers either side of the aeration
chamber):
•
Remove the access cover(s)
•
Empty the Tricel Duos plant using the vacuum tanker. Ensure the solids are removed with the
liquid.
Care must be taken not to damage the Tricel Duos plant with the hose of the vacuum tanker.
•
Replace the de-sludging access cover securely
