Fault Possible cause Rectification
The treatment performance of
the plant is unsatisfactory.
Most of the above given defects
can lead to a reduction in
treatment performance.
In addition, there can be many
reasons given for unsatisfactory
discharge values, such as:
• insufficient oxygen supply
• Faulty position of the
submersible aerator
• leaking of the tank
• discharge of large
quantities of detergents or
disinfectants as well as
other non-permitted
substances
• (paints, solvents, etc.)
• sludge disposal not carried
out
• faulty settings of the
population figures
• plant disconnected from the
power supply for longer
period
In the interests of the
environment you should get in
contact with your service
operation in order to achieve an
improvement in the discharge
values.
