The emptying of sedimentation tanks with the MOOS KSA-SYSTEM and
the treatment of sludge.
The KSA-System (Combined sludge
tanker and dewatering system) has been especially developed for
the rapid and effective emptying of a large number of sedimentation
The KSA-unit solves the same problems as a traditional sludge tanker.
Additionally, the contents of the sedimentation tank are dewatered
The unit can be equipped with a suction tower and a high-pressure
jetting pump etc, in order to meet customer requirements.
Advantages of emptying
sedimentation tanks with the KSA-System in comparison to ordinary
The KSA–system dewaters sludge from the sedimentation tanks
into a dry sludge mass of 15 – 25 % dry matter. This results
in a reduction of up to 90% of the sedimentation tanks contents.
After dewatering, the pH-neutral reject water is lead back to the
sedimentation tank. This ensures that the sedimentation tank is
functioning optimally immediately after emptying. Refilling of the
sedimentation tank with reject water avoids using expensive natural
The capacity of the KSA-unit is between 20-40 sedimentation tanks
each day. This provides for an effective working day and alleviates
the need for constant emptying at wastewater treatment plants, and
therefore reductions in terms of transport costs and wear on the
The dewatered sludge can be lime stabilized in a MOOS Lime-sludge
mixing plant. Due to its high contents of nitrogen and phosphor,
it can be used as valuable fertilizer in farming or be used to increase
the quantity of topsoil where this is required. This allows for
great savings in treatment costs for delivery of septic sludge at
the wastewater treatment plants.
Foreign particles in the sludge such as stones, glass etc –
are separated by the grating system of the KSA, and can be deposited
separately on a supervised waste site, or at an incineration plant.
This prevents plastics, glass, stones and metal shavings etc, being
spread together with the sludge. If desired, the dewatered sludge
can be delivered directly to a wastewater treatment plant; either
to a receiving station or pumped directly into the inlet at the
wastewater treatment plant.
