Smell
Symptoms Corrections
Smell escaping from
the covers on the
plant
If venting is via the inlet pipework, ensure that the outlet T-
vent is closed and the inlet T-vent is open. If venting is via
the outlet pipework, ensure that the inlet T-vent is closed
and the outlet T-vent is open. Also check the seals around
the covers and reposition as necessary.
Smell escaping from
the kiosk
Check that any ducts to the plant (holding tank or pump
chamber if installed) are sealed with expanding foam.
Plant smells Check that grease has not entered the treatment plant. Do
all the 'Annual Checks'.
POOR AIR DISTRIBUTION OVER THE FILTER SECTION
Cause Correction
Blocked air Diffusers
(NOT relevant to
the T3HP Hire
Unit)
VALVE
TOP
UNION
TO
DIFFUSER
LEG
Turn off all but one of the air diffusers at the valves. Then
proceed to check the one that is on for the position of bubbles.
The increased pressure should clear any blockage in the
diffuser. If not the diffuser can be removed by switching the air
supply (blower) off and disconnecting the diffuser tube at the
top of valve, turning through 90o and lifting up through the
diffuser access slot. On early units the diffuser is screwed into
the fitting on the end of the tube and can be removed for
cleaning or replacement. Later units have a cap with a 5mm
hole in the end. In addition there are also some cross holes on
some of the horizontal pipe. Clear all holes.
UNSCREW
DIFFUSER LEG
Repeat as required for any other suspect blocked diffusers, and
then move the air diffusers by angling the tube as required to
improve air distribution.
Filter media partially
blocked by excessive
biomass
This indicates that the plant is overloaded, check design
loading and contact WCSEE for advice.
Filter media partially
blocked with sludge
This indicates carry over from primary tank, check sludge
levels and de-sludge if required. Also check for excessive flow
possibly due to ground water ingress into foul sewer.
