TROUBLE SHOOTING GUIDE FOR BIODISC UNITS
SYMPTOM CAUSE ACTION
Strong odour Excessive build up of
sludge and scum
Desludge the unit.
Grease (white/cream
crust in primary tank
and/or thick, smooth
biomass
1
)
De-sludge unit. If necessary hose off discs. Avoid
excessive use of fats and oils. Please note removal of
Biomass will reduce treatment until new Biomass
establishes.
Chemicals in the system
(very sparse or no
biomass
1
)
In most instances, units will recover naturally from toxic
inhibition events. See general guidance on use of domestic
chemicals.
Excessive laundry use
(thick, stringy whitish
biomass
1
on first section)
Spread out laundry operations. Avoid biological powders
where possible and use the minimum possible amounts of
detergent. .
Unit overloaded
(thick/grey biomass
1
) over
most of rotor
Check section for the process capability of the unit. If in
doubt, contact Klargester.
Rotor stopped See rotor stopped section below.
Drains inadequately
ventilated
Check that there is an open high level vent at the head of
the drains (not tile vent or “Durgo” valve).
Rotor stopped Switched off Check that the motor switch on the panel is in the “on”
position. Re-set if necessary.
Power failure Check the fuse/trip at the supply board. Replace/re-set as
necessary. If the problem persists, contact Klargester.
Wiring fault Have the wiring to control panel checked by a competent
electrician. If the supply wiring is OK contact Klargester.
Drive chain broken Contact Klargester.
Drive motor faulty Contact Klargester.
Loose pulleys on rotor or
gearbox output shaft
Contact Klargester.
Rotor fails to re-
start after a
stoppage
Rotor unbalanced Consider Hosing off excess Biomass on the heavy side of
the rotor. Note removal of biomass reduces treatment.
Loss of rotation
alarm not
operational
Rotor Sensor out of
alignment with bracket
Adjust one or both
Rotor turns
intermittently
Drive motor overheating Contact Klargester.
See strong odour and rotor stopped sections.
Managed flow system
in-operative.
Check that bucket(s) are in place and discharging correctly
into the biozone second stage.
Sludge return pump
inoperative
(ND/NE/NF/NG only)
Contact Klargester.
Unit flooded Drain outlet blocked. Check drain downstream of unit , Check location, ? is unit
correctly installed and recessed
Effluent
discharge not
to required
standard
