RECOMMENDED METHODS FOR COLLECTING EFFLUENT SAMPLES*
ALARM PANEL & BLOWER INSPECTION AND MAINTENANCE
1. Listen for any loud rattling sounds. The blower should hum softly.
If a rattle is heard, ensure that all four legs securely contact the
ground or base medium.
2. Inspect the filter once the power has been disconnected by
removing the filter retention screw. Then, remove the cover by
snapping the filter cover off the top of the blower. Clean the
filter by knocking the dust out or by rinsing with water to remove
accumulated particles. Be sure the filter is dry before reinstalling.
Proper effluent sample collection technique is essential for obtaining
an accurate assessment of treatment efficiency. To accurately interpret
treatment efficiency, influent as well as effluent samples should be
collected. In the event of reduced efficiency, influent composition can
be useful in determining system owner practices. Depending upon
configuration, effluent samples can be collected at:
1. Disposal pump tank downstream of the Fusion ®
2. Fusion ® discharge chamber
3. Distribution Box downstream of the Fusion ®
Samples should be obtained in clean, one liter bottles. Bottles should be
labeled appropriately to denote the sample’s original location and kept
on ice during transport. Samples should be collected to approximate
daily residential sewage flow. When opening the Fusion ® lid during
sampling, try not to disturb the unit. Also, do not collect the effluent
sample from the wall of the tank.
For further information, reference procedure identification number
SOP-F-103, Clarus Environmental, 1-800-928-7867.
* Consult local rules and regulations to determine jurisdictional effluent
sampling requirements.
Inspect the alarm panel for signs of water or odors inside. Toggle the
test switch on the side of the box to check that both the alarm horn and
the alarm beacon light are operational.
Inspect the blower and switching valve for proper operation. If the
blower is not functioning, refer to the troubleshooting section near the
end of this guide.
TROUBLESHOOTING
1. Odor
Offensive odors are often the result of insufficient or inappropriate
bacterial growth. Causes may include a young or unestablished
system, insufficient air introduction, or the addition of detrimental
chemicals or poisons into the system. Ensure the blower and
air delivery systems are functioning. Check with the homeowner
regarding chemical use and disinfection habits. Check all risers
and lids to ensure an airtight seal.
2. Foam Formation
Foam formation is observed in the following situations:
a) In the early stage of operation when the
aerobic bacteria colony is establishing itself,
b) when an excess amount of air is supplied for aeration,
c) when the difference between ambient
temperature and water temperature is great, and
d) when an excessive amount of detergent is
introduced.
In most cases, foam will disappear with proper operation. When
excessive amounts of detergent have been introduced to the
system, remind the homeowner to use appropriate amounts of
detergent.
3. Cloudy Treated Water
• Check the amount of scum and sludge: If too much scum or
sludge is observed, transfer them to the first chamber and adjust
recirculation flow rate, frequency and duration. (See backwash
flow adjustment, pg. 10)
• Check the aeration situation:
If uneven bubble generation is observed, adjust valve (1). If
aeration is weak, flush the aeration pipe with air or water.
• Check the recirculation flow rate:
If the recirculation flow rate has increased
after the last inspection the aeration pipe may
be clogged. Flush the aeration pipe with air or
water. If the recirculation flow rate has decreased after the
last inspection, the airlift pump or recirculation pipe may be
clogged. Clean them with a brush and running water.
4. Blower
Blower Motor Does Not Run, with Power Connected:
• Check the electric supply to the panel, ensuring 120 volt
to blower power.
• Check that all breakers and fuses in the panels are on or intact.
Little or No Aeration:
• Check the blower motor is running.
• Check the air line piping connectons at the blower and
switching valve.
• Check the air filter and clean or replace if necessary.
• Check the diaphragms and replace if necessary.
• Check the air piping for leaks, clogs, or dislocations and fix
accordingly.
• Verify check valves (if installed) in supply lines are installed
correctly.
