9. Operational failures and resolving them
Premier Tech 54 / 64 Solido SMART
DOKK5110E 15.04.2020
Not enough
oxygen (O 2)
in the SBR
reactor, possibly
followed by odour
build-up/ poor
purification
efficiency, etc.
The aeration is
not working or is
insufficient because the
tube diffuser is installed
incorrectly
The function of the tube diffuser
can be checked by switching it
on in manual mode.
Check the position of the tube
diffuser (horizontal,
approximately in the centre of
the container floor?).
a. The tube diffuser is
not receiving enough
compressed air
Check:
Whether the compressor is
performing optimally during
other functions such as
feeding (check filters if
necessary).
Whether the white hose is
damaged or bent.
Whether hose
connections/nozzles are
damaged, including in the
capsule.
The valve is either defective
or not activated correctly by
the controller.
Increase the aeration period
on the control unit
b. Tube diffuser pressure
loss is too high
(calcification, silting,
etc.)
c. The aeration/
deaeration for the
overall plant is not
functioning correctly
Measure the tube diffuser
counter-pressure using the
pressure gauge, record the
water level, replace the tube
diffuser if necessary (contact
Premier Tech)
Ensure there is sufficient
aeration/deaeration
(unhindered circulation)
