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.

Inspect the filter once the power has been disconnected

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.

SOP-F-103, Zoeller Pump Company, 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
