Original Operating Manual for KLARO Small Wastewater Treatment Plant V.15.07
Observation
Possible Cause
Corrective Action
•
The air hose to the drain lifter is
leaky,
•
Flooding in the receiving water
doesn't allow water to drain from
plant.
•
Controller is defective.
and clean lifter
•
Have SBR reactor pumped out
and seal hose connections
•
Wait until flooding subsides,
•
Contact maintenance company
The plant emits
odours, the treated
wastewater is cloudy
or discoloured
•
Too little air is supplied to the plant
•
One-sided aeration due to defective
membrane unit
•
Have aeration time increased by
service company
•
Verify aeration diagram, contact
maintenance company
Aeration diagram is
one-sided and large,
isolated bubbles are
rising
•
Membrane unit defective
•
Leaky seal on aeration bar
•
Contact maintenance company
•
Contact maintenance company
Solenoid valves are
unusually loud when
switching
•
Valve seat of the solenoid valve is
dirty
•
Unscrew and clean the solenoid
valve
8.3.
Possible failures of solenoid valves
Observation
Possible Cause
Anchor does not pick up.
•
Supply voltage is interrupted or insufficient.
•
Magnet coil defective.
•
Anchor blocked in polluted tube space. If the anchor does not reach
the stroke end and the AC coil is powered, this will result in failure
of the coil after a short time (thermal overload)
•
Nominal voltage doesn't match coil voltage.
Valve does not close.
•
Anchor blocked!
•
Nominal voltage is still present.
Valve does not open.
•
Nominal voltage is not present,
•
Magnet coil defective.
•
Nominal voltage doesn't match coil voltage.
