Maintenance, Repair and Operation
The system must always be turned on.
As the operator of a small wastewater treatment plant, you
must
ensure trouble-free operation of the plant. Almost all operating faults result in a deterioration of the
treatment performance of the plant. These must therefore be detected early and eliminated by you or by
a qualified service technician.
Fall Hazard
When working near the open cover of the septic tank, there is a hazard of
tripping and falling!
The open tank must be secured by appropriate measures. Operators and/or third
parties could fall into the tank! Children are particularly at risk!
Due to biodegradation processes in small wastewater treatment plants,
formation of (possibly toxic) gases can be expected. For this reason an entry into
the plant must always be secured by a second person. Under no circumstances
must an unconscious person be followed. Instead request help as soon as
possible.
High Voltage
For activities other than the operation of the control, the maintenance switch
must be turned to the "0" position or the plug of the cabinet must be pulled!
Work such as maintenance and repairs to the cabinet equipment must be
performed by a service engineer or an electrician!
7.1. Sludge Evacuation
There are different types of sludge in a small wastewater treatment plant. Only the faecal sludge, which
accumulates in the first chamber, is evacuated. It consists of sedimented residues of the wastewater
treatment. In small wastewater treatment plants, the faecal sludge or treatment sludge consists of dead
microorganisms of the biological treatment stage and the settled solids from the pre-treatment. The
amount of accumulated sludge in the sludge storage is measured by the service technician using a
sludge lancing lifter. The system is designed so that the sludge storage space is sufficient for permanent
full-load operation and compliance with the operating and maintenance requirements for at least 12
months. At a lower load, this period is extended accordingly. Timely sludge disposal is necessary to
