MAINTENANCE
Special attention should be given to the maintenance of the oil separator to ensure
effective operation throughout the life span of the system. The need for maintenance
depends on the location and purpose of the system. If the separator system is used to
process waste waters produced at vehicle washing sites or for other purposes where the
separator system is exposed to a degree of solid matter load, its operation should be
monitored and maintenance procedures performed more often than e.g. in systems
which process rain waters gathered from aspha lted areas.
4.1
Emptying the oil storage space
1.
The oil alarm unit SET/Omega 112 will switch on a signal light when the oil storage
space is full.
2.
Drain off the oil layer as the full storage volume is reached, or at least after every six
months. The oil is drained manually through the oil skimming pipe of the separator.
If there are two maintenance shafts in the separator system, the skimming pipe is in
the second shaft. When skimming the oil layer or draining the tank, be careful not to
damage the coalescing units.
3.
Set the suction hose of the container truck to the skimming pipe and begin to suck
off the oil layer that has gathered on the surface of the separator. Stop sucking when
the surface of the separator sinks to the lower level of the suction grooves or the
pump starts taking in air.
Note!
The layer gathered on the surface of the separator is
hazardous waste.
4.
The alarm probes must always be cleaned, when oil waste is drained. If necessary,
wash the probes with mild detergent (e.g. dish washing liquid) and set them back in
their places. Also check the operation of the alarm unit and probes, as described in
the installation and operating instruction of the alarm unit.
4.2
Maintenance of the filters
The coalescing 3D filters should be regularly cleaned, at least once in two years, to
prevent their blockage and decrease of the effluent quality. However, if a blocking
alarm is signalled by the SET/Omega 112, cleaning must be done immediately.
1.
Start the cleaning by draining the separator completely. Lift the filters straight up
through the maintenance shaft with a hoist or crane. Take out the filters, one at a
time.
2.
Clean the filters with tap water using a high pressure washer so that the washing
water flows into the separator. Alternatively, clean the units in a place where the
washing water can be directed to a place where it is processed. Also clean the dirt
from the separator walls. Drain the washing water completely from the separator by
using the suction hose of the container truck before mounting the coalescing units
back.
3.
For a more thorough cleaning, the filter may be disassembled into parts. The filter
consists of several slices which are connected by bars inside the centre cavity. The
bars are connected with each other and their upper ends are fixed to the filter lid. On
the lid, there is also a handle for lifting the filter.
4.
Open the fixing nuts from the filter lid, disassemble the filter into parts and clean
the parts with a pressure washer. Do not aim a strong dot spray at the filter. Lead the
