MAINTENANCE
Every sewage treatment plant needs regular maintenance as does the upkeep of drainage fields and drains.
This is the responsibility of the owner/user.
We recommend that plants are maintained by qualified service personnel, however some self help and an
awareness of normal operation is helpful in identification of a larger problem.
If the plant appears not to be operating correctly, refer to the Fault Finding section of this manual.
MAINTENANCE SCHEDULE
DAILY
Check the operation of the compressor. It should be possible to hear it running by standing close to the unit.
MONTHLY
Check the operation of the compressors (bubbles should be rising in the reactors and media should be seen slowly
rotating).
Visually check that the inlet and outlet zones are clear of debris.
Visually check the biomass growth on the filter media. The biomass colours should vary from light brown colour,
(not white or grey.) to rich brown. Odour from the plant should be 'earthy' and hydrogen sulphide odours
('rotten eggs') should not be present.
Visually check the final effluent. If cloudy or containing many suspended particles, then the humus and or
primary tank is likely to require desludging.
THREE MONTHLY
Assess the depth of the thickness of the floating sludge in the primary and final zones.
Check the blower filter, and replace if necessary. Note. The filter will collect dirt particles from the air and the
location of blower/inlet will influence the frequency of filter change.
ANNUALLY
The unit is designed to be emptied of sludge every 12 months
