Production of sludge
Important
•
The desludging of the Tricel Vitae is the responsibility of the homeowner.
•
There is the potential danger of falling into the tanks during desludging when
manholes may be open – take all necessary safety precautions when
desludging.
•
Do not allow machinery/traffic drive over the Tricel Vitae. Maintain a distance of
at least 4 metres away from the manhole covers on the Tricel Vitae.
•
The manhole covers should never be left off an unattended Tricel Vitae.
When the sludge is occupying 50% of the volume of the primary chamber desludging is
required. This activity is necessary when the sludge is 700mm deep. View the desludging
periods in the table in section 3.1 ‘Dimensions,’ these periods depend on the occupancy of the
dwelling. The Tricel Vitae has a separate desludging access point. Desludging is carried out with
a vacuum tanker (Tricel recommend the use of a licensed company).

Desludging (emptying the solid waste from the primary
chamber)
•
Qualified personnel must perform the desludging.
•
Please remove all floating and settled sludge from the primary chamber. All compartments
within the primary chamber must be desludged (please refer to section 3.2 ‘Tank Drawing’).
The primary chamber is identifiable by the fact that there is no aeration done in this
chamber. Therefore, there will be no air bubbles in these chambers during the aeration
function.
•
Once the primary chamber has been desludged, fill it with fresh water. When loading the
primary chamber with fresh water, place the hose into the primary compartment and
position it closest to the aeration chamber. By doing this, it will reduce the risk of floating
solids blocking the airlifts.
