Process failure
Process failure from oxygen starvation of the biomass:
If the biomass is starved of oxygen, the typical odours associated with anaerobic
bacterial treatment will be noticed. This is caused by insufficient air flow into the
biological zone. A blockage in the air line or blower is the most probable cause.
a) The inlet screens have been located on each end of the blower housing. If one
screen becomes blocked by debris, the opposite screen should still be sufficient.
The suggested routine preventative maintenance calls for brushing off the screen
as needed. The configuration of the inlet screens and the required maintenance
will protect the unit from oxygen starvation due to insufficient air flow.
b) The blower is equipped with an inlet air filter. If this filter becomes blocked with
debris, it could cause oxygen starvation of the biomass. The blower inlet filter
should be checked every 6 months and replaced as needed.

Visual evaluation
Wastewater backup is characterised by wastewater flowing back into the house or
slow movement of wastewater in the drains. This may indicate a problem with your
wastewater treatment system unit. Identify where the backup is occurring within your
plumbing system. If you cannot locate material blocking the drain contact your service
provider.
No use for an extended period
The Oasis Series 3000 Wastewater Treatment System will function normally even if
wastewater does not enter the system for 5 days.
The power to the system should be left on during short periods when there is no
wastewater flow to the system. If the system will not be used for several months or
longer, you should contact your service provider so the system can be checked for
proper operation and serviced if necessary. A slight odour may be detected for a few
days while the system returns to normal operation.
