2. Notes

2.1 Safety

Observe the national accident prevention regulations during all work. Particularly for inspecting the tanks,
a second person is required for safety reasons.

Furthermore, observe the valid national regulations and standards during installation, assembly, mainte­nance and repair work, etc.

During all work on the system or parts thereof, always shut down the entire system and secure it against
unauthorised re-start.

Always keep the tank cover closed, except when working in the tank. Otherwise, there is a high risk of an
accident occurring. Only genuine GRAF covers or covers that GRAF has approved in writing must be
used.

GRAF offers an extensive range of accessories, which are all coordinated to one another and can be
expanded to form complete systems. The use of accessories that have not been approved by GRAF re­sults in the exclusion of the warranty/guarantee.

2.2 Ventilation and bleeding

All tanks must be ventilated and bled. Additional ventilation lines or ventilation openings must be ordered
if necessary. Ventilation lines should be ordered to guarantee natural ventilation (chimney effect).

Bleeding with a free outflow Bleeding with percolation or an obstructed outflow

3. Construction and functional principle

3. Construction and functional principle

The small wastewater treatment system is fully biological and works according to the retention process
with long-term aeration. The system is made up of an aerobic stage. A scum board is used to split this
stage into a coarse substance chamber and an activation chamber. The chambers are connected to one
another in the bottom section. During this process, therefore, all domestic sewage is immediately exposed
to aerobic wastewater treatment. The entire system is aerated due to compressed air being blown in and
the sludge activated as a result of this biologically cleans the wastewater.
