7.3 Trouble Shooting
The JetFlex Tube Diffuser TD 63/2 requires very little maintenance for long term operations because
of the use of high-performance materials. Gummi-Jaeger GmbH Aeration Components recommends
a periodical visual inspection of the diffuser system, especially for the occurrence of deposits and the
pressure drop. This should allow the operator to determine if the aeration system is performing at
optimum levels.
Below one can find indications of disturbances and procedures for repair.
1. Indication:
Large volume of air in localized area
Possible cause:
Leakage in lateral piping
Procedure:
Drain basin to access area in question, maintain medium air flow, check
connectors and pipes for evidence of breakage, repair or exchange
Possible cause:
Diffuser membrane is damaged or missing
Procedure:
Drain basin to access area in question, maintain medium air flow, inspect
visually diffuser, exchange membrane or complete diffuser
2. Indication:
Non uniform bubble pattern
Possible cause:
Insufficient blower capacity
Procedure:
Confirm blower operations, switch on additional blowers
Possible cause:
Check valve of drop lines closed or not open enough
Procedure:
Inspect position of check valve
Possible cause:
Incomplete air distribution to diffusers
Procedure:
Drain basin to access area in question, check diffuser horizontal levelling,
level within tolerance of ± 0,6 cm / ± 1/4”, inspect piping and joints for inter-
nal clogging from debris, air purge or water flush cleaning
Possible cause:
Deposits on diffuser membrane
Procedure:
Inspect diffuser membranes for deposits and encrustation, clean or exchange
membrane or exchange diffuser
3. Indication: Decreasing of dissolved oxygen level, increase of system pressure
drop
Possible cause:
Deposits on diffuser membrane
Procedure:
Inspect diffuser membranes for deposits and encrustation, clean or exchange
membrane or exchange diffuser
4. Indication:
Non uniform dissolved oxygen profile throughout basin
Possible cause:
Insufficient air volume
Procedure:
Confirm blower operations, switch on additional blowers, check equipment
and operation conditions, see 1-3
Depending on type of waste, individual constructions and operation conditions other causes can lead
to disturbances. If necessary contact the contractor or engineering office.
